48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Flagstaff.
At nearly 7,000 feet on the Colorado Plateau, Flagstaff has one of the lowest baseline barometric pressures of any US city. The city's mountain climate brings snow, monsoons, and dramatic daily temperature swings that each carry pressure implications.
Worst season for migraines: November through March and July through September. Flagstaff's 7,000-foot elevation on the Colorado Plateau creates a mountain climate unusual for Arizona. Winter brings Pacific storms that drop heavy snow, and summer monsoons produce daily thunderstorms. The thin atmosphere means pressure changes represent proportionally larger shifts than at sea level.
Common triggers in Flagstaff: monsoon thunderstorm pressure drops at high altitude, Pacific winter storm frontal passages with heavy snowfall, extreme UV radiation at 7,000 feet. Flagstaff sits at 7,000 feet at the base of the 12,600-foot San Francisco Peaks, the highest point in Arizona. Despite being in the same state as Phoenix, Flagstaff's climate is radically different, with 100+ inches of annual snowfall and summer temperatures 30 degrees cooler. The Mogollon Rim escarpment to the south acts as a trigger zone for monsoon thunderstorms, and the ponderosa pine forests surrounding the city moderate some weather effects but also contribute pollen and wildfire smoke triggers.
Typical pressure: Flagstaff averages 790 hPa at rest, but storm systems can push readings down to 775 hPa. Swings of 8-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Flagstaff weather trigger migraines?
Yes. Flagstaff experiences 8-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include monsoon thunderstorm pressure drops at high altitude, Pacific winter storm frontal passages with heavy snowfall, extreme UV radiation at 7,000 feet.
What time of year are migraines worst in Flagstaff?
Migraine sufferers in Flagstaff typically report the highest attack frequency during November through March and July through September. This aligns with the period of greatest barometric volatility in the region.
How do I track migraine triggers in Flagstaff?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and Flagstaff's weather conditions over time.
