48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Billings.
Billings sits at 952 metres in the Yellowstone River valley beneath the Rimrocks, sandstone cliffs that line the northern edge of town. Pressure averages 906 hPa, and chinook winds off the Beartooth front can reorder conditions within an hour.
Worst season for migraines: December, February and January. Midwinter alternates between Arctic air pooling in the valley and chinook events that scour it out. Each reversal carries a substantial pressure change, and the two can trade places several times in a single week.
Common triggers in Billings: Beartooth front chinook warming, Arctic air pooling in the Yellowstone valley, rapid multi-directional winter reversals. Chinooks descending the eastern slope of the Rockies compress and warm as they fall, capable of raising temperatures 30 degrees in a few hours while humidity collapses. Billings experiences these more often than most Montana cities because of its position at the mouth of the valley. When the chinook fails, Arctic air fills the valley instead, and the swing between the two states is the defining feature of local winter.
Typical pressure: Billings averages 906 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 890 hPa. Swings of 6-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Billings weather trigger migraines?
Yes. Billings experiences 6-12 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Beartooth front chinook warming, Arctic air pooling in the Yellowstone valley, rapid multi-directional winter reversals.
What time of year are migraines worst in Billings?
In Billings the most barometrically volatile stretch of the year falls in December, February and January. 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 Billings?
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 Billings's weather conditions over time.
