Global Barometric Variation – Annual Maps and Monthly Raw Data


When I published my first post on Avoiding Migraines Resulting From Changes In Barometric Pressure in 2013, I had no idea how many fellow migraineurs would read, engage, and comment.

“Hi guys, OK so this really does work. I suffered when I lived in Virginia. Moved to Georgia, no headaches, moved back to Virginia, headaches, moved to Delaware, suffered horribly. The worst ever! Found this article, moved back to Georgia, no headaches. I’m so serious, I can live now.” – Kyle

I have been touched by the gratitude shown by many of the readers, and inspired that I have been able to help others–if not with their migraines directly, then at least with a better understanding of one apparently common migraine trigger. Many were happy to see some useful data that could help them understand the barometric pressure characteristics of places where they lived or were considering moving to. Others asked me where I got my data, some wanted to see hourly variation, and many others wanted to see global variation data.

Could u be kind & send me a list of the best worst places to live in Western Europe. I am hoping your list will identify the best place to live in UK I suspect all of the UK will be bad but I am stuck until I can retire & cant move to Spain or Malta until then…Thank u God for guiding me to this site. – Harry

For those who wanted more, this post is for you.

(The Usual Disclaimer: I’m not a doctor, and am in no way qualified to give medical advice. I organized this data for myself and for the benefit of those who believe that living in a place with less barometric variation could be good for their health, so that they could see which cities have more or less barometric variation.)

Where I Got My Data

Although the original data set I used to compile my original U.S. list does not seem to be online any longer, I was able to find a global dataset at the FTP site in the National Climactic Data Center (NCDC) public area of the National Oceanic and Atmospheric Administration (NOAA), which contains barometric pressure readings for more than 11,700 weather stations around the world. Downloading all data from 2008 through March of 2016, I constructed a database of over 322 million barometric measurements, many of them taken at intervals as short as 15 minutes.  The database size weighs in at just under 10 gigabytes. There’s so much data, in fact, that my first task was to take a sample to see if hourly or every-15-minute data would prove to be more useful than 24 hour data. If I could research global barometric variation using the daily data set, it would really save on computing resources and allow me to publish results much more quickly.

Hourly Variation

I chose 13 weather stations distributed through the world which were in larger population centers (as opposed to weather rafts or remote air force bases), and which had hourly pressure data available since 2008–there were only 476 of these to choose from, the vast majority of them in the U.S. (320) or Canada (129). I then compared the percentage of days per year that experienced my standard migraine-inducing daily variation threshold (a .20 or greater change between 24 hour measurements) with a new hourly variation threshold: a .02 or greater change between any two hourly measurements). I selected the .02 hourly threshold because, like a .20 pressure change over a 24 hour period, a .02 pressure change in an hour occurs at approximately a 20% rate throughout the data set.

Here are the data on hourly variation:


Here are those data plotted for correlation:


Other than the outlier–Denver (which as a high altitude city can expect to have greater measurement error, greater true variation, or both)–it seems reasonable to conclude that daily barometric variation is an excellent proxy for understanding hourly barometric variation.

Global Variation Data

Using daily changes, I was able to construct both a master list and several maps showing the annual barometric pressure variation of the world cities.

Let’s show the maps first, because they reveal some rather amazing patterns regarding barometric pressure variation.

Note: If you want to see the maps in full screen mode, you can click on them to get a full screen slideshow. You can also right-click and then open each image in a new tab, and if you do this, on the new tab you can zoom the browser in to closely examine the a region of interest.

The World


First, you can see that there’s not much red (more than 50% of days reaching the .20 threshold variation is quite rare on this planet), so for the most part, blue means very few days of high pressure variation, green means more days of high variation, and yellowish colors mean a lot of days of high barometric pressure variation. For my migraine patterns, I would live anywhere that is colored dark blue without a moment’s hesitation, and I would not want to live anywhere green and certainly not anywhere yellow. (Anecdotally, my migraines have been at their worst the times I have lived on the U.S. East Coast, and at their best when I have lived in California).

Second, you can see that these variations are almost perfectly related to latitude, with practically zero variation in the tropics, and latitudes in the Northern Hemisphere generally showing lower variation than counterpart latitudes in the Southern Hemisphere. There are some interesting exceptions:

  • Coastal California, Portugal, Italy, and the Balkans seem to have considerably smaller pressure variation than would be expected from their latitudes. So these are likely better than expected places to live for migraineurs.
  • The United States East Coast has high variation relative to its latitude.
  • The United States Mountain Time Zone has very high variation relative to its latitude.

Next, you can review eight detailed zoom-ins on the global map.

North America

The further south, the better, except for California, which is all blue. It is worth pointing out that there is a material difference between Crescent City, in extreme Northern California (12% of days annually cross the .20 threshold) and San Diego (1% of days), just not enough to change the colors on this particular map. (Interested viewers can download the raw data spreadsheet at the bottom of this document for more details.) Also of note, some of the highest barometric variation in the world occurs in North Dakota for some reason.


Eurasia and North Africa

Europe and North Africa follow latitudes pretty closely, with the biggest surprises in the United Kingdom and Japan. Ireland has much higher barometric variation than expected for its latitude. The East Coast of Central Japan has shockingly high variation given that it’s on the same latitude as places with almost no barometric variation like Tel Aviv, Lisbon, and Islamabad. Norway also seems to be a bit worse than comparable latitudes in Sweden or Finland.


Africa and South Asia

Ah, tropical living! Except for the unexpected swath of pressure variation in Coastal South Africa, living anywhere on this map would have you pretty safe from pressure-induced migraines.



Oceania follows latitude predictions as expected. Sydney has low variation, Melbourne is moderate, and New Zealand can get extreme on its wild southern end. I have no idea why Sydney and Melbourne don’t show up on this mapping software, where instead we see Newcastle and Traralgon.


South America

Very high and narrow mountain ranges such as the Sierras and Andes seem to throw off latitude correlation. In South America, there is a line of exceptionally high variation on the Eastern edge of the Andes. This is similar to the line of exceptionally low variation on the Western edge of the Sierras in North America.


Western Europe

In Western Europe, there are very few measurements available in Germany for some reason. As mentioned earlier, Ireland and Scotland have shockingly high pressure variation, presumably related to the legendary wind and rainfall in those areas. (In addition to not be a medical doctor, I’m also not a meteorologist. I’m just a guy who gets a lot of migraines when the barometric pressure changes, and I’m happy to know that I shouldn’t ever visit Ireland in January.) I don’t understand the blue dots in the area of Northern Poland and Lithuania, but maybe migraineurs there are getting a little bit of a break. Or maybe there’s some measurement error there.


United States

I’ve written a lot about the United States in prior articles, so I just leave it at wondering this: why does central North Dakota have the highest barometric pressure variation on the planet? If you go about 500 miles due east or west, you get to Duluth/Superior or Missoula, where there’s still a decent amount of pressure variation, but nothing like the worst variation on Earth. Denver is also much, much worse than you would expect. Another case of being on the Eastern edge of a large mountain range? Or perhaps more measurement error?



Canada is really not a good place for migraine sufferers who are triggered by changes in barometric pressure. The best major cities in Canada seem to be Vancouver, Toronto, and Montreal, so at least that covers a reasonable percentage of the Canadian population. Flin Flon, Manitoba seems particularly bad. Yes, I just wanted to write the words “Flin Flon, Manitoba”.



Zero Days of .20 Variation Over 2,000 or More Measurements

For those of you who would like to visit a place that has not experienced a single day of .20+ variation since 2008, and for which we have at least 2,000 recorded pressure measurements since that time, there happen to be 245 such places on this planet. Note that many places between the tropics have certainly had zero days of .20+ variation since 2008, but do not appear on this map because we don’t have 2,000 measurements for those places. This would likely be the case with much of Africa. To get a good look at this map, you can right-click on the map and select “Open image in new tab”, and then zoom in on the image.



The Raw Data

Saving the best for last, perhaps, feel free to download this Global-Barometric-Pressure-Threshold-Variation Excel spreadsheet. It contains the threshold variation percentage for every weather station with at least 50 daily change measurements since 2008, and the spreadsheet tabs provide both annual and month-by-month data. The spreadsheet is 3.5 MB is size, and so might take a little while to download on slower internet connections.

So, for example, if you live in Cape Town, South Africa, you could go to the Annual tab of the spreadsheet, use Control-F to search for “CAPE TOWN”, and see that at the Cape Town International Airport (CAPE TOWN INTL) has 14% of its days throughout the year (51 days) experience a barometric pressure variation of .20 or higher. If .20 pressure variation triggers a migraine headache every time, then a migraineur who lives in Cape Town could expect at least 51 migraines per year while living there. If you want to see whether this varies by season, which it does in every place that I’ve examined, you could go to the January tab, use Control-F to search for “CAPE TOWN”, and see that only 4% of days in January (perhaps one day each January) experience threshold variation. So the summer in Cape Town, as with most places, is a time of much lower barometric pressure variation. Looking at the winter in South Africa, in July, shows that 23% of days in July (an average of 7 days each July) experience threshold variation in Cape Town, which would be problematic for a migraine sufferer with a barometric pressure variation trigger.

This spreadsheet is the best way to see the month-by-month variation for the weather station closest to where you live.

        TJ, I want you to know your amazingly generous work sharing this touches more than just your fellow migraine sufferers – I’ve had 13 spinal surgeries and have been loosely tracking for years the impact barometric pressure swing has on me and found a direct correlation with pain. It’s never been about the pressure on any one day, instead it’s always been about the variance. The greater the spread, the sooner, longer, and depth the pain goes: However, most interestingly it creates different pain types. I know this doesn’t sound that far fetched or maybe it’s not even surprising but here’s the deal as; lower variances only create localized pain around the damaged parts of my spine, while greater variances trigger symptoms near identical to impinged nerves needing surgical repair, including inability to even walk. I don’t know why it creates the nerve symptoms as I had imaging done early on during one such episode and no physical impingement was seen on the MRI.

        Now that I’m medically retired due to the disabilities associated, I have been unsuccessful in looking for data just like this to help me plan where to spend my retirement as I’m of course basing it on the standard deviation of barometric swings. I couldn’t find anything with the detailed level I needed for the data to be helpful until this. See, usually a large enough variance has to happen within 24-48 hours to trigger the harsher symptoms, while a gradual increase of the same amount over 7-10 days will have relatively low to no noticeable impact. Symptomatic impact can occur anywhere from 24 to 36 hours prior to, and up to a 3-5 days post deviation; variances occur of course. So please know your your data collection was the only way I was going to be able to get the information I needed to help locate a region where I have hope of being able to walk each day, which is the gift of physical freedom ~ Cheers mate!

          Robert, Thank you for the information you shared regarding spinal surgery and related pain. I too have had 30+ major surgeries from 4 major accidents and most of the surgeries were orthopedic with severe damage to the cervical, thoracic and lumbar spine. I now live in Oregon and 7 out of 12 months I suffer regularly with so much pain. I knew it had something to do with the barometric pressure change of .2 inches in a single day but always knew there was more information. Thank you so very much for this additional knowledge. I will track pain now looking more closely at the variables you have mentioned. So grateful for this site as well. I do not have migraines but have horrific body pain related to orthopedic injuries or surgeries. Most doctors do not understand even when I share this information. When I lived in Southern California I was always so happy and now I understand why as so few of the days are affected by large variations in barometric pressure. Thank you to everyone for their valuable input over the years. I share this webpage with so many medical professionals and friends. One day I hope there will be more answers as to precise causes for each type of pain and especially how we can strengthen our bodies so they are not as affected by the barometric pressure changes. Best wishes of Health to Everyone!

            One more note. I use often and customize the 10-Day forecast to show Barometric Pressure, Humidity, Precipitation and Cloud Cover. For example on June 23 2019 in Portland Oregon I was sitting at my desk with no pain and in a matter of minutes the pressure of pain began increasing in my body. At the moment the pain began to cause such difficulty it was affecting my breathing, I often look at the weather forecast. I went to to pull up the current local weather.10-Day forecast. Exactly at that moment the barometric pressure had been steeply rising for 3 hours and was currently at 30.13 haven risen from 30.04 three hours ago. Within less than a 12 hour period the Barometric Pressure went from 30.04 to 30.30, .26 inches. They have a slide ruler you can move to a certain point in time and get the exact readings for each weather element. I take print screen shots and record my pain levels and any relevant information around it. I have gotten more serious about gathering details around each episode, searching for answers and solutions.

            Due to recent injuries again, I started using a retail version of a PEMF (Pulsed ElectroMagnetic Frequency) intensity pad on my spinal column at its highest level for 10 minutes. I’ve just done this for the past month or so. PEMF recharges the red blood cells and helps micro circulation improve. That’s all I know. The result I am seeing is the area on which I use the PEMF pad feels stronger and has significantly less pain than the other areas where I have never used the PEMF pad.

            Thank you Robert for the information about the nerve pain as I also have the same experience. Again, thank you to everyone who has helped this forum move forward with valuable information.

          I am suffering from migraines, nausea, muscle tension every time a storm rolls in, which is getting more and more where I live. What gets me is even though this is helpful, I am doubting the fact that all the areas in blue are more stable. I don’t get it at all. Those areas in blue along the gulf of Mexico?? HMMM… I don’t see it, this area produces many more storms. I know because I live in metro Atlanta and the storms have gotten worse, the pressure worse, I am moving ASAP I am in agreement with you that its definitely for me the time frame, if it build up slower its not so bad if its faster its horrific for me. I would like to know where you ended up moving because the person who did this site its great but I am quite certain that if he suffers from migraines and lives in Atlanta that he is enduring them right now. Anywhere in blue would be a BAD mistake for me to move to.

      I go to global air weather then click the site aviation weather. That will open up to a page highlighted in the middle click on where it says noaa then when that opens up go near the upper left corner. There will be a box for a city near you that has an airport type in the closest city w/airport I believe you just wait and it will pop up. Mine is Santa Fe Mm. The space mine goes to has 3 options. One of them is 3 days also highlighted when I click on it gives hourly readings including barometric pressure. Hope that helps.

    We have referred to your article countless times JT Taylor. Our son is the poster child for this article. Thank you so much for this information. We recently took a vacation over spring break to test this theory. We live in northeast Indiana.

    We traveled through Indiana, Kentucky, Tennessee, Alabama, Florida and Mississippi. He never got a migraine once while we were out of the horrible state of Indiana. We were so shocked. He was a completely different kid it was insane. When you feel great you act differently.

    We are praying that we can relocate so that our son can feel great and enjoy life to the fullest. I cannot thank you enough for publishing this information.

I had noticed the weather played a huge part in the pain. Unfortunately, I too, have passed the pain onto my 2 sons. One gets them more than the other but it saddens me. I had no idea this is hereditary. Or it stands to reason, at least. My father also suffered from migraines. He lived in Illinois then in Utah.

    Living in Denver I can confirm the pressure does change as indicated. As a migraine sufferer I have become a better detection device than scientific data and instruments. I did live in Birmingham AL for a year and had a noticed difference in my migraines (I still had bad ones there), having since moved back to Denver they have become daily severe debilitating ones, I have had to take a leave from work (stress increases them also) and am currently looking for better ways to treating them (moving is not an option at this point ).
    I find your information great and validating. Thanks for doing so much research to help others.

      Diane says:

      I live in Fort Collins, Co and i have been tracking the barometric pressure for a few years. The variation here is extreme at times and seems to be getting worse with more crazy weather patterns coming through. Anyway, I experience headaches and basically all over chronic fatigue which feels like I have lead in my legs and I also experience depression and hopelessness when this happens. Hard to walk up stairs or even sit up in a chair. This only happens where there is a pressure change. On days with stable pressure, I feel totally normal. It makes me feel like I am going crazy, and its hard to explain this to anyone else. They look at me like I am making it up or its all in my head. It has been so encouraging to read that other people experience similar symptoms from barometric pressure variation. When I go to Florida I feel amazing and happy and do not have any fatigue or headaches or depression. Hoping to at least be able to spend winters there at some point.

    Nice study and presentation. When I grew up in California I never got headaches but when we were stationed in Adak, Alaska I got headaches all the time. One day I was looking at our barometer in the house and came to the conclusion that when the barometric pressure changed by a large amount I got a headache. Glad to see that there is a study done that proves that exact hypothesis.

    Thomas Feick says:

    I have a few ideas about the outliers.

    North Dakota is in the sweet spot for experiencing polar jet stream changes. This plays havoc with the weather.

    Southern California’s weather is steadied by the warm ocean.

    The same forces that created tornado alley fiddle with the barometric pressures of the Great Plains.

    Denver suffers from being on the edge of the mountains, the edge of the plains, and the edge of the Jet Stream.

    Thanks for the excellent work. Statisticians everywhere are proud of you.

  8. John Mitchell
    John Mitchell says:

    I am an Australian ( Sydney) and my son aged 21, who is non verbal and has Autism (ASD) from his MMR vaccination ( immediate adverse response) . He has an extremely sensitive brain response to variations in barometric pressure (BP) as well as radio wave towers. He has agonising migraines from BP changes exceeding 5hPa= 0.15″ Hg in 5 hours , or 10hPa = 0.3″ Hg over 48 hours. To ‘lessen’ the migraine pain, he pounds his head against the wall and with his fists. He never does this except when having a migraine. Its becoming life threatening, but almost all neurologists know NOTHING about BP induced migraines. The Australian Bureau of Meterology( ABOM) have not analysed their BP data to determine which Australian cities are the most stable BP cities ( SBPC). I can buy their data , but dont have software to analyse the data to calculate the ?? standard deviations ?? of BP variations ( daily/hourly) . Once I determine the most SBPC in Australia, we are moving there, or if we find say Hawaii USA is THE most SBPC, the we shall move there. MR JT TAYLOR, THANK YOU SOOO MUCH FOR ALL YOUR PUBLISHED ANALYSIS, ( eg Global Barometric Variation – Annual Maps and Monthly Raw Data ) . CAN YOU PLEASE TELL ME WHAT MATHEMATICAL ANALYSIS YOU USED TO ANALYSE THE BP DATA? I would publish the analysis for all the Australian cities on this blog / web site.
    Thanks . John Mitchell.
    I am in Seattle USA on medicals for my son, and today 3 to 4 April 2016, we had a 18 hPa ( 0.53 inch Mercury) continuous rise in 27 hours and my son’s response was a tonic-colonic seizure.

    • JT Taylor
      JT Taylor says:

      Hi, John. My analysis steps were:

      1) Gather all data from NOAA FTP site for all 25,000+ global weather stations, 2008-2016
      2) Eliminate stations with measurements occurring less frequently than daily
      3) After verifying very high correlation between hourly and daily data, delete all measurements after the first measurement of each day UTC time (this got the data small enough where I could run queries that would finish in 12 hours instead of 12 days)
      4) Calculate, for each day for each weather station, whether 24 hour change was at least .20″ Hg in either direction
      5) Create maps and spreadsheet based on the percentage of 24 hour measurements that differed at least .20 Hg from the prior day’s measurement

      After working with two different data sets over the last two years, I would be very surprised if the map was much different whether analyzing .15″ change over 5 hours, .20″ change over 24 hours, or .30″ change over 48 hours.

      I also have edited my post to include a map of zero-variation locations, which sound like they could be helpful for your son–this map appears towards the bottom of the post.

      Hi John,

      I’m just seeing this post now. And to me it sounds like your son doesn’t have migraines but cluster headaches. Cluster headache is more common in men than women, and banging your head or fists against the wall is a very common symptom. Normally with migraine any movement would hurt more! Injections of imigran & pure oxygen inhaled at 10liters a minute through a non-rebreather mask can abort an attack. Please find a neurologists specialised in headaches, they are out there! Also, cluster headaches can be related to air pressure – that’s why I was looking at this website 🙂 Hope this information helps you out!

      The best of luck with your son!

    Elisa says:

    This map is great for anyone who has migraines that are triggered by a specific a level of barometic pressure which stays pretty constant, but in my case it is the rapid change in pressure caused by quick passing storms that trigger my attacks. I used to live in England and rarely had migraine attacks, it wasn’t until I moved to Florida I started having problems. If sudden temporary changes in barometric pressure don’t really trigger a migraine for a sufferer then yes Florida is a great place to be as most of the time the pressure is great. However, for migraine sufferers like me it is the massive sudden changes the storms bring that triggers our migraines. In Florida Barometric pressure basically rollercoasters during our typical daily thunderstorm (which pretty much start to crank up in March and then pretty much happen daily until late October). The pressure rapidly changes and then returns back to normal within a couple of hours. In my case I need the barometric pressure to remain as constant as possible. This explains why my migraines got progressively worse when I moved to Florida, even though the pressure is ranked worse in England by the map at least it was reasonably steady. So if the average level of pressure is a trigger this map help. However, for sufferers like me, where abrupt changes in barometric pressure are the migraine trigger the map is not helpful, as the issue is more complicated.

      Susan says:

      Yes!! That is my situation exactly! I live in Georgia and between 2-3 every day from April until October, I am prone to a migraine due to rapidly changing pressure readings and “summer/afternoon showers”. It is agonizing! I also need for the pressure to remain as constant as possible…if that’s possible. Right now, I think I could be a weatherman/person myself. I hope you find relief soon. I’m very thankful for this research and for all the time and effort you have put into presenting it so well.

    Thank you for this in-depth information.

    Migraine and Meniere’s have many of the same triggers. Many people with Meniere’s disease are affected by barometric changes that trigger vertigo, ear fullness and tinnitus. Knowing good and bad location based on barometric change is very helpful to us. So many thanks for your efforts.

      I’m stunned by the response about both vertigo and migraine association. I moved from San Diego to Virginia 15 years ago Gradually allergies worsened and previously diagnosed ” sinus infections” did aas well and are now called migraines and are obviously connected with pressure variation. I was recently diagnosed with VPPD a kind of vertigo. SAN Diego looks better than ever. Just wish our house there hadn’t tripled in value. May have to go back and find a tiny healthy place. Thanks so much for your work.

    Hi JT Its Harry from UK

    Thanks Buddy, sending u a big hug from Barometric Badlands of the British Isles.
    U can visit in September its gorgeous here during that month but never visit in winter or spring. If u visit there will be a delicious pizza or fish & chips waiting for u

    JT, this is so invaluable and much dedication has clearly gone into this. I’m currently studying the affects and changes of BP with my migraines and Meniere’s as part of my daily log now and am definitely starting to see a pattern more debilitating, challenging days when the BP increases. I’m in Vancouver, Canada and I have to disagree with the notation about it being one of the more steadier BP cities. We get a lot of rain here too so that doesn’t help either.

    Thanks again for all of your work here and sharing it with us!

      The impression I meant to leave readers with about Canada was the first sentence: “Canada is really not a good place for migraine sufferers who are triggered by changes in barometric pressure”. Maybe I should have written the word “really” twice or three times. There’s just a ton of air pressure variation all throughout Canada, as you would expect given its latitude. But to me the data indicate that it’s clearly better to live in Vancouver than in Flin Flon, just as it’s clearly better to live anywhere less than 30 degrees latitude than in Vancouver.

    Dalton says:

    Thank you for this information. I suffer from joint pain when barometric pressure is low. When it’s high, my pain is nearly nonexistent. I have wondered what’s parts of the world have typically higher barometric pressure. In the tropics perhaps? Do you have general data on that? Thank you.

  14. Sara Honeycutt
    Sara Honeycutt says:

    Thank you so much – I have been compiling my own charts and barometric pressure observations on my health – there are many other health issues affected by the pressure change. I have severe Chronic Fatigue Syndrome & many brain symptoms from this, and the pressure changes in Northern New Mexicowhere we live devastate me. My family and I are planning to move to Hawaii later this year, and I’ve been tracking their barometric pressure & see that it basically almost never drops below 30. Your information is so incredibly invaluable, I would like to see it posted on other health sites as well, I believe most immune system related disorders would benefit from this information. Bless you to the fullest.

    I would also like to point to the post about Florida’s rapid daily roller coaster barometric changes during the rainy season, and emphasize this thoroughly for those looking to move to Florida. The daily thunderstorms could play complete havoc for you, as they are exactly as the poster noted, and why I am moving to Hawaii instead of Florida, where I grew up and am familiar with their weather patterns (FL).

      Monica says:

      Good call Sara! I moved to Florida 5 years ago and my migraines have increased exponentially. I am now leaving during the summer months. I am still looking for the best place that has low humidity, temperate temperature and little variation of barometric pressure. My migraines are triggered by high heat, high humidity and frequent barometric changes. As I type this reply I am in the 17th hour of a migraine.

    Hi JT, you did a great job here, thanks a million! It helped me tremendously in understanding why I have felt so much better in the past at different locations in the world.

    I’ve got a small suggestion: a map with just the contours of the countries, and the city names, or a monochrome version would let the colors of the spots stand out better.
    Anyway, it’s already great as it is, I think certain regions on the Earth can expect a big influx of migraineurs the next few years, thanks to you! (as a matter of fact; I wouldn’t mind living in a migraineurs colony somewhere; finally an end to all the explaining and misunderstanding and we can rub each others backs:-))

    I want to say thank you…. As a Retired Air Force NCO I’ve been a few places. I also suffer with chronic migraines and cluster headaches. There were places that I always felt more “comfortable” and never knew why. You research has provided me with a mountain of information to that I can make better travel decisions. I am sending this to all my fellow sufferers. Its not a cure but it
    empowers me to make more informed decisions. Right now that is such the blessing. Keep up the good work. Too bad I can “LIKE” this page or rate the information. You would get 5 Stars and 2 thumbs up from me.

      Brenda Porter says:

      Same with me. My husband is retired AF and we’ve moved around a lot as well. Georgia has been secondly worse to Charlotte, NC. I’ve lived here 9 years and cant wait to leave. NC is the worst then Ga, Montana, Utah, then Greece. The island of Crete was the best for me. NC’s jumps in temps also bother me. We are moving to Fl next month. I heard about the daily rain in the summer there but when it moves in and out quickly it doesn’t bother me. I think this is why the weather really didn’t bother me in Montana because it would come in and go before you even knew it was there. In NC and Georgia it lingers forever. The clouds, rain etc.

        How are you in FL? Where in FL did you end up? I am in Wilmington, NC which is far better than Boulder, CO but still not good. The weather here is brutal and all over the road. I wish I never would have moved here. We are looking at moving but Southern California is just too expensive and I don’t know what a better option is. We are looking into Jacksonville, Austin, and Las Vegas. In that order. I really hope I don’t get stuck in NC for another year as this past year was pretty awful.

    I was first diagnosed with meneires when living in the Missoula region along that path across Montana. It was aggressive and at it’s worst. I would eventually move to north mid section of the state and lived for 10 years with little or no problems. A year and a half ago we moved to southwest Missouri. I have had one attack, two drop attacks and 5 out of 7 days a week suffer dizziness, nausea, and have lost significant quality of life. Am visiting Montana right now and my meneires symptoms have improved greatly. Tornado Ally is not a meneires friendly place. Thanks

    Catherine Waugh says:

    Thanks so much for this data! In a previous version you listed 5 cities worldwide with the lowest pressure variation. On of those was Santiago, Chile. Is that still the case? And does time of year count? For example, we are now heading into Chile’s winter when there is more rain. Would that make a difference in terms of pressure variation?

  27. Kim
    Kim says:

    Hi JT, Thank you for all your hard work. I have a neurological disease called Trigeminal Neuralgia. I have lived in Duluth, MN for the duration of this disease. The reason for this disease can be several things. Most commonly a blood vessel pressing on the Trigeminal Nerve is the reason. Barometric pressures can cause our pain to increase substantially. This disease is dubbed the Suicide Disease. It is the worst pain known to man. I have had the treatments, meds and homeopathic treatments, but I can’t change the weather. Minnesota is not the place for me. Again, thank you for your hard work. This information is helpful while we make a decision about moving so I can have a better quality of life.

    • JT Taylor
      JT Taylor says:

      Hi, Kim. I’ve been noticing a lot more comments lately from other readers mentioning that the U.S. Southeast and Tornado Alley of the Midwest, while they seem to have reasonably low barometric variation on the map, are bad for their specific set of symptoms. For me, even knowing that my migraines are pressure-induced, and looking at my own map and seeing reasonably low variation there, I would never move back to coastal North Carolina. I think this is probably because my data is not properly capturing intra-day changes (but I don’t have enough data to prove or disprove this conclusively). If my migraines were a whole lot worse to the point of being completely unmanageable, I would immediately move to San Diego or Los Angeles, where I grew up and had symptoms much less often than I do now. But if I’d never lived in a place I was considering moving to, I would surely want to arrange to spend at least a couple of weeks, if possible, “scouting” a place to see if it made a difference for me, before I went ahead with the expense and disruption of a move. Best of luck to you!

  28. Cathy Waugh
    Cathy Waugh says:

    Hi JT. Many thanks for all of this great data. Before you recently updated this post, you listed five cities worldwide with the lowest barometric pressure fluctuation. One of these was Santiago, Chile. Would you still consider it one of the five, as I no longer see this list of cities? And does your data refer to a particular time of year (eg. summer or our winter) or would it apply all year round? Many thanks!

    Howdy from South Texas. I live between San Antonio and Corpus Christy. I have some migraine issues but my main problem is rheumatoid arthritis. I’m 63 and have had many miserable years of swollen joints. I’ve always felt the barometric changes is what sets them off. This year has been the worse. I am going to go to Tucson Az. to see if the dryer and more even barometric will help. The summers in Texas are usually better so hope I can get enough relief to pack my bags. Thanks for this info. I’ll post how Tucson does.

    Thanks so much for the info & all the work that went into this, JT! I’ve been researching this for years & it’s the best info I have found. I’ve been a chronic, severe BP change headache sufferer for 35+ yrs. It continues to get worse (I’m in my early 50s) & has become debilitating most days. Depression, chronic fatigue, and social withdrawal have also resulted. I’ve tried neurologists, ‘classic’ migraine prevention treatment & medications, and have had 3 sinus surgeries, nothing helps. I’ve lived in Atlanta 29 yrs and realized long ago that I have to move- just need to feel better, often & long enough, to prep my house to put it up for sale.
    Again, I can’t thank you enough, and wish your information were available to more people like us. Your detailed data & maps confirm and expand on our research, provide a ton of new info….. and perhaps may be shared with those in our lives who may not understand, perceive us as exaggerating or hypochondriacal.

    MaWaSi says:

    This is great work, and beneficial for people with many ailments. Fibro, inner ear, Sinus, Migraine. I think the data could be crunched real time using some of Google’s new tools. All the processing is done on their servers. On the clinical side, many people seem to have their own triggers, and can feel a pressure change days before or after. Would be interesting to see a map showing various data factors ie duration of pressure change vs temp vs humidity.

    But still this is a great accomplishment, many thanks.

    • JT Taylor
      JT Taylor says:

      Your comment on sinus & inner ear effects is really interesting. I wasn’t aware of this. Has a well-known correlation been established between sinus or inner ear and barometric pressure variation? An ENT colleague of mine just launched a new YouTube channel, this is the kind of thing she would probably get into digging into on the medical side…

      Also, you’re surely right that Google could help with this, but sadly these days I just don’t have any time to researching this further, and maybe more to the point, I strongly suspect that the data would still point in the same general direction no matter what I did with it.

  32. Amy Unruh
    Amy Unruh says:

    JT, how can I ever thank you for this information? Based on this, my husband and I went for a visit to Florida, Sarasota area. Though my pain didn’t change much, it was more comfortable, and I think part of why my pain didn’t decrease much was because of the stress of an 8-hour delayed plane flight and a mix-up in seats (supposed to have a handicapped seat that reclined. Had regular seat. I had to upgrade 1/3 of the way into the flight and neither of us got any sleep that night because of the delay.) and a flight and trip in general. On our 3rd day there, though, the pressure was 30.0 and I felt so much less pain for 5 hours. I didn’t take pain medication until the afternoon. The major difference, though, was in my chronic fatigue. I’m usually so fatigued that I can do very little. A trip to the store usually does me in. But I was on the go for our entire trip. It was so amazing. I wasn’t running marathons and had to pace myself because of the pain, but it wasn’t my lack of energy holding me back. Oh, JT, how can anyone really understand unless they’ve been sitting at the doorway of death like me? We’re moving to Florida!

    • JT Taylor
      JT Taylor says:

      It’s good to hear that you got some relief. How long were you in Florida? Before uprooting my entire life, job, friends, house, etc., I personally would want to spend at least several weeks in a place to feel more sure that the move was the reason for the relief (and not something else, like maybe being on vacation away from a stressful job, or the like), and then I’d probably try to go back in a different season if I could. But I don’t know your situation, and as I’ve said many times, I’m not a doctor and am not qualified to give any advice to anyone about managing health symptoms, so I’m just telling you how I would think about it if it were me personally. (I’m also a very cautious person, and tend to look, oh, a few dozen times before I leap!)

    Robyn says:

    I’ve lived in Fargo, Chicago, and now in south Florida (2 hours north of Miami), and here in Florida is the WORST it’s ever been. The entire summer is one giant migraine (days on end). I’m researching possible places to move and everything I read tells me that Miami is my best bet, but NO!

    Any suggestions from people who’ve moved away from Florida?

    • JT Taylor
      JT Taylor says:

      Based on the comments throughout this post, and my own personal experience living in North Carolina, I would not feel comfortable trusting any of my data for the Southeastern United States. There’s the old joke, “if you don’t like the weather in North Carolina, wait 15 minutes”. I found that to be true. I think there’s a good chance that my data set is not capturing intraday changes properly. I personally would never move to Florida for my migraines. I moved back to California, where I grew up, and to me it’s as good as it gets here.

  34. Tamra
    Tamra says:

    I live in Northern California, and we’re considering immigrating to New Zealand for retirement. I have mild to moderate sleep apnea mostly controlled by a dental appliance. However, my apnea gets worse when the pressure drops. I also get fibromyalgia flares with low pressure. From your data, it doesn’t look like I’d be comfortable anywhere in New Zealand. I tried clicking on the map but couldn’t quite make it out on my iPhone, but are those areas on the North Island dark green or almost blue? Is there any area at all in New Zealand where I might be able to live comfortably? Thanks.

    • JT Taylor
      JT Taylor says:

      Hi, Tamra.

      First of all, to clarify, my map indicates _variation_ in pressure (how often does the pressure change from low to high or high to low), not the _level_ of pressure (low or high).

      Here’s a site that has average _level_ of pressure for U.S. States:

      It seems like most states have a pressure average around 30.00, except for areas in the Southwest, which seems to average more around 29.90 or so. Given that Alaska and Hawaii are very far from the U.S. mainland, and Colorado has lots of mountains and Illinois doesn’t, and Arizona has a lot of desert and Washington State is really wet, the fact that all these average levels are so close to each other indicates that you’re probably correct in assuming that you care more about the variation than the level, but it’s worth checking, right? So I looked here––and it looks like Auckland also centers around 30.00 (or 1015 millibars, which is how New Zealanders measure air pressure).

      As far as air pressure variation in New Zealand, it really makes a pretty big difference where you are. From my map it looks like you would want to be as far north as possible. Although keep in mind that my map seems to be inaccurate in some places (for example, the U.S. Southeast seems to have pressure vary a lot more than my data would seem to indicate). In my data set, Auckland averages only 13 days per year of high (>= .20) variance, which is almost identical to San Francisco. Wellington, much further south, has more than twice that many. So, not as good as, say, Hawaii (0 days, ever), but much, much better than anywhere in Canada or the United Kingdom.

      • Tamra
        Tamra says:

        Thanks for you response. I think my comment was worded incorrectly. My apnea gets much worse with low pressure, while my joint pain is affected by sudden variations in pressure. The apnea is my main concern, so I’d like to find a place that has very little variation but also stays near 30.00 most of the time. I’m usually very comfortable sleeping when it’s 29.98 or above. It sounds like Hawaii would be the best choice for me, but maybe I’d be comfortable in Whangerie, NZ, or possibly one of the coastal towns northwest of it. I’ll need to do more research. Thanks so much for your feedback.

    Stacie Randall says:

    Hi JT, as a migraine sufferer, I am also affected by barometric pressure changes. Thank you for the valuable information your article provides. I have lived in a number of different cities across the US. I am originally from New York and experienced migraines living there and also in the New Haven Connecticut area. I lived in San Diego for a bit as a teenager before I was diagnosed with migraines, so I didn’t really reap the benefits there! I also lived in Las Vegas and I did notice I had fewer migraines while living there. I currently live in Colorado, about 50 miles north of Denver. I love it here, but I had no idea the barometric pressures change here so often until living here. I get the most headaches living here and they’ve become debilitating. Last month, December was really bad. I really don’t want to move but it may be something I have to consider. My question is, I know the Denver area barometric pressure fluctuates a lot, do you know if there’s other area’s in Colorado where it’s better to live for migraine sufferer’s? I really like the mountain town Bailey, I’m used to high altitude so the altitude difference there doesn’t really bother me. It’s also in a “banana belt” region so the weather is warmer in that area as opposed to surrounding towns. I thought it wouldn’t hurt to ask if you have any information of areas in Colorado that may be more comfortable for a migraine sufferer.

    Abby says:

    Thank you so much for your map! Using your data, I relocated from Seattle, Washington to Thailand and I have had zero migraines in Thailand it’s been AMAZING. In Seattle, I only ever felt all right for July and August. December and January were typically almost unbearable for me.

    Interestingly, I tried to move to Vietnam (Hanoi), in winter time, and had absolutely awful migraines there, so I left and am back in Thailand.

    I am so so grateful to you for all this data you have shared, it truly changed my life. Your website is one of the only sources I could find for data on barometric pressure variations for the world. I am doing so many things now and really enjoying my time and feeling productive and relieved to no longer have migraines.

    Bonet Rene says:

    Thank you for all your research. I am a nurse and I am so very aware that some places are just better for some people to call home. Of course medical science is not even considering the weather and its affects on humans. I am certain over the span of centuries it this this very thing that caused certain groups of people to migrate over vast regions even before locomotion was invented. My question is specific to California, wondering if northern (Shasta) has any benefit over say Corona? Keep up the great work! I am certain one day Medical science will be looking to you for help. When people want to reduce the medicines they are using to supposedly be better, realizing there is a better way.

    • JT Taylor
      JT Taylor says:

      Hi, Sue. My data don’t show any large differences in 24-hour variation within small areas like part of a city. Having said that, I live in the Bay Area now, and there are clearly a number of microclimates here. A few days ago it was around 70 degrees in San Francisco and over 90 degrees 10 miles east of Oakland. My wild guess is that it would probably be better to be closer to the ocean than further because closer to the ocean the weather changes less and air pressure and weather seem to be at least loosely correlated, but there might be a simple meteorological explanation for that which has nothing to do with air pressure–I’ve analyzed all this data and placed it here in case someone finds it useful, but I’m certainly not a meteorologist (nor do I have time to become one!) and so I don’t really understand the science behind the relationships between these different atmospheric metrics.

        Hi JT,

        Thanks so much for your invaluable work. It was depressing to read that Canada is generally a bad place to live in terms of barometric changes. That said, I had trouble interpreting the map. Would you be able to list a few better places and a few worse? I live in Toronto, something tells me that’s one of the worst….


        • JT Taylor
          JT Taylor says:

          Hi, Ilan. When I zoom in on the map, it looks to me that Toronto would be about the second best place to be in Canada, probably due its lower latitude, a little bit behind Vancouver and ahead of Ottawa and Montreal. Newfoundland, Nova Scotia, and Saskatchewan appear to have the most variation according to the standards I used.-JT

            Hi everyone and thanks for all of your input. I myself live in Toronto, Canada, and my migraines here are terrible, last summer I couldn’t go out at all. With the humidity and heat, over 30 C’ most summers, it’s a nightmare to live in. So I have been looking to relocate elsewhere, preferably still somewhere in Canada. I have also been to Ottawa in the summers, and it’s pretty bad up there too, constant up and down pressure changes.
            I am originally from Estonia, which in my experience has been the worst place for a migraine sufferer. My dad also gets terrible migraines in Estonia, doesn’t matter north or south. But whenever he gets out of the country his migraines also decrease by a lot. (A side note about Estonia, whenever there’s a thunderstorm coming up, All fresh milk products curdle).
            I have also lived in Ireland for a few years, mainly in Cork city region, and honestly I don’t remember getting any migraines, perhaps 1 in 3.5 years.
            In addition, I have done a lot of dietary changes to alleviate headaches and migraines from foods and drinks, but as for weather, theres nothing I can do about that, at this time but be indoors with windows closed in AC’d space during humid and hot Toronto summers.

    Thanks for the data. I had terrible migraines in Raleigh, NC, no migraines in Boone, NC, no migraines in Wilmington, NC for 2 years, migraines in Birmingham, AL, and I just recently moved to Seoul, SK and I have moderate level of migraines here. The worst is by far Raleigh, NC. I was hoping Seoul would be migraine free but it’s not. I need some help on choosing where to move next. I was considering moving back to Wilmington, NC or even Los Angeles, CA. My migraines make it too difficult to live life. I need to solve this. Thanks for all your help.

    • JT Taylor
      JT Taylor says:

      There’s no way to know whether we have the same or different migraine triggers, but I grew up in Los Angeles and lived as an adult in Wilmington for 5 years. Los Angeles is the best place I’ve ever lived for my migraines, by far. Wilmington was not nearly as bad for me as when I lived in Philadelphia and Boston, but not nearly as good for me as the various places I’ve lived in California. Within California, I have found Los Angeles to me much better for me than the Bay Area (where I live now), and a little better than Fresno, which was actually quite good for my headaches.

    I love in SW Florida around Fort Myers area and rainy season is migraine season for me. My normal 10 plus a month somewhat controlled by meds sky rocket to one every day it rains so daily 30 days a month it’s not uncommon for me to be hospitalized 3-4 times during rainy season. I also have a very damaged spine but due to a rare arterial – venous malformation in the middle of my spinal cord at C4 no surgery for me. If not from BP changes what would you suggest might trigger the migraine. The 4 different doctors I have gone to for some kinda of relief besides major drugs, the last suggested the weather is causing it. Move out of Florida! I’m 63 and retired so I could.

    • JT Taylor
      JT Taylor says:

      Hi, Andrea.

      As an engineer, I am presenting data about global weather patterns on this post. I believe that these patterns affect my migraines, but do not have anything close to 100% proof of it. As for anyone else’s migraines, there are others who believe that weather patterns affect their migraines, but I have also read that the causes of migraines are still mostly unknown to science. For me, after doing this research I know I would never consider living in New England or the upper Midwest, even if I were offered a dream job there. As for others, I just don’t know how strong the causation might be between atmospheric pressure changes and migraines. I think as far as the causes of migraines, the best plan is still to work with your doctors on that, because they’re the professionals who are kept the most abreast of advances in our understanding of migraines and their causes.

    WOW, what a great find! Thank you for this. I had a concussion 10 yrs ago and have never had a cessation of headaches and extras since. The only relief is from less bad days. No medication or treatment has ever helped. I noticed that things would be worse on windy days and days when the weather changes rapidly. I live in Southern Ontario, Canada so we are the place where you have to dress for any possible weather at any given time of time day. Even my commute home has sometimes brought me through 5 different types of weather. This information will definitely help me plan my next move as things are desperate.

    What you’ve done here means SO much to SO many of us with chronic pain of many types. THANK YOU from the bottom of my heart!! Your data is one of my top criteria for suggesting places for us to move. Since you know CA so well, can you tell me anything about where the Central Valley (e.g. Clovis) ranks in terms of BP changes? Is ANYWHERE in CA with low BP changes more affordable than the other areas of that state?

    Also, I have tried many times to get your raw data link to open, and it keeps just showing this same web page in my Favorites bar. Any suggestions?

    Last, for all who wonder what type of BP pattern is affecting you, I saw a web page that listed different types of headaches (sorry, still staying to find the link again!). It differentiated Migraines and Migraine-like headaches as being triggered by opposite patterns. Migraines were triggered by high BP, while Miraine-like headaches were triggered by lows. I don’t recall the role of quick vs. slow changes. But having spent much of my life in the Chicago area, I can tell you that my Occipital Neuralgia and Chronic Myofascial Pain and Fibromyalgia are for sure triggered by lows and changes (in Chicago, we say, “wait 5 minutes and the weather will change!”). I can tell you a day ahead when a storm is coming.

    My thoughts go out to you and all my fellow pain sufferers here! I’ll keep looking for that link tomorrow.

    Thanks so much for your hours of work putting all this together. I do wonder if the hourly/daily correlation works for Central Florida, as we often get significant BP variations by the hour because of the sea breeze effect storms. This seems to be as big an issue for migraines as daily changes. A friend of mine said “stay away from any place where the saying is ‘If you don’t like the weather, wait 5 minutes'” and I tend to agree with that.

    This changed my life! I moved to Bangkok from Seattle and I can fully engage in and enjoy my life! No medication no migraines just enjoying! Thank you for this article!!

    Hello JT,
    I am now in Rome, Italy and came to Italy because I noticed much decrease in chronic severe nerve and muscle pain in Cosenza. While there, a local older man told me that many people who visit the area also experience the same pain relief.
    I had the same pain relief in Mexico City, Mexico. However, by traveling by bus from Mexico City’s extremely high elevation to a lower one in Morelia, I experienced excruciating
    pain. When I explain these experiences to most doctors, they laugh at me. I thank you very very much for your research.
    Also, sitting in the sea water greatly reduces the pain. I’m planning to live in an area of Italy with stable air pressure on sea side and get well.
    I’m searching for other areas in Italy that have same air pressure variances as Cosenza, Calabria, Italy. (After searching many months, I have not yet found an affordable place to stay there. It would be different if I knew Italian language.) I tried to zoom into your map of Italy, but cannot. It’s not clear. I’m hoping to see exact places…so I can get on a bus and go there today.
    I followed your link of your raw data, but it brings me back to the original map.
    Could you please tell me how I can find the information I’m seeking?
    Thanks for all,

    Dr. Taylor, It’s probably been years since this was active, but I would love to talk to you. Are you on LinkedIn?

    Dear JT! I stumbled upon your GREAT WORK and this is truly amazing! Thank you so much for this! I suffer from migraines and even a slight change of pressure triggers them. What is curious that sometimes I don’t get a headache if the pressure is dropping slowly and gradually over a couple of days. I live in Warsaw, Poland most of the time, the rest of the year in Badalona, Spain (close to Barcelona). The difference is huge although Barcelona is also not pain-free for me. Poland is simply horrible and as you commented, I think the blue spots in the north are due to some mistake in data processing. Polish seaside can actually be even worse with constantly changing pressure, rain, cold wind, etc. In general, I feel here like I have a constant tornado in my head and in the wintertime is much worse. From Europe, so far the worst is definitely Holland, it was unbearable for me there.
    So far I haven’t found any place where I can get rid of my migraines entirely but I’ll keep on looking 🙂 I’m no longer alone because now I have your data. Thank you!

    Thank you for your kindness in sharing this very helpful information that must have taken a great deal of time to compile. I hope you are able to maintain this site into the future.

    Thank you so much for this information! This information has changed my life! I have been suffering so much and I am going to do everything I can to get back to a place with more of a stable barometric pressure!

    I just found this site with all your work, never dreaming there would be such a thing. Thank you so much! (I’ve always liked Barcelona, now I have reason to go there!)

    I hope this post catches your attention. Thanks for all of your hard work on the relationship between variation of barometric pressure and migraines. Also, with the web awash with stupidity, kudos to you for your intelligent approach.

    Migraines have been an enormous problem in my life. My wife and I are shopping for our retirement home in a better migraine climate, and no it won’t be in Virginia. Is there an interactive map of the continental US so I can zoom in to Norther California?

  1. […] Changes in barometric pressure are my biggest struggle. When first learning about how barometric pressure change can trigger migraines I stumbled upon a fantastic resource: a list of US locations and their yearly amounts of barometric pressure change. The author gets his date from the National Climatic Data Center (NCDC). You can find a link to his raw data and additional global data here. […]
