48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Fort Collins.
Fort Collins sits at 1,525 metres where the plains meet the foothills, with pressure averaging 846 hPa and swings reaching 12 hPa. The Cache la Poudre canyon opens directly onto the city, channelling mountain air down into town.
Worst season for migraines: February, December and March. December through March brings the largest barometric moves, driven by a mix of upslope storms and downslope chinook events that can occur within the same week. Spring runs nearly as active as winter along this stretch of the range.
Common triggers in Fort Collins: chinook and upslope flow reversals, Poudre canyon wind acceleration, rapid 25-degree temperature seesaws. Northern Colorado experiences a phenomenon locals call the temperature seesaw, where chinook winds can raise readings 25 degrees in hours and then reverse just as fast when the flow shifts back upslope. Each reversal carries a pressure signature. The canyon mouth also produces local wind acceleration that does not show up in regional forecasts.
Typical pressure: Fort Collins averages 846 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 830 hPa. Swings of 7-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Fort Collins weather trigger migraines?
Yes. Fort Collins experiences 7-12 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include chinook and upslope flow reversals, Poudre canyon wind acceleration, rapid 25-degree temperature seesaws.
What time of year are migraines worst in Fort Collins?
In Fort Collins the most barometrically volatile stretch of the year falls in February, December and March. That is when weather is most likely to play a part, if weather is a trigger for you at all.
