48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Ann Arbor.
Ann Arbor sits at 269 metres in the Huron River valley, on rolling terrain west of Detroit. Pressure averages 984 hPa, and its inland position means it misses most of the lake moderation that keeps the lakeshore milder.
Worst season for migraines: February, March and December. Late winter and early spring bring the largest barometric moves, when systems tracking through the Great Lakes are at their most frequent. The interior position means colder outcomes and sharper transitions than the shoreline sees from the same storms.
Common triggers in Ann Arbor: continental air mass exposure between the lakes, glacial terrain frost pockets, rapid late-winter transitions. Southeast Michigan sits between Lakes Michigan and Huron without being close enough to either for strong lake effect, which leaves it exposed to the full continental pattern. The Huron valley's rolling glacial terrain produces local frost pockets and temperature variation across short distances, noticeable to anyone tracking conditions closely.
Typical pressure: Ann Arbor averages 984 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 965 hPa. Swings of 6-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Ann Arbor weather trigger migraines?
Yes. Ann Arbor experiences 6-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include continental air mass exposure between the lakes, glacial terrain frost pockets, rapid late-winter transitions.
What time of year are migraines worst in Ann Arbor?
In Ann Arbor the most barometrically volatile stretch of the year falls in February, March and December. That is when weather is most likely to play a part, if weather is a trigger for you at all.
How do I track migraine triggers in Ann Arbor?
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 Ann Arbor's weather conditions over time.
