LiveWeather & Migraines in Seattle
Pacific storm systems arrive frequently from the north Pacific October through March. Persistent low-pressure systems keep Seattle's pressure consistently in the 990–1010 hPa range during winter — among the lowest sustained averages of any major US city.
Seasonal Pattern
Highest risk: October–March. Seattle's prolonged low-pressure winters are a well-known challenge for migraineurs.
Managing Weather-Triggered Migraines in Seattle
Check pressure before high-risk activities
Before long outdoor events, travel, or other plans where a migraine would be disruptive, check the forecast for upcoming pressure drops.
Preventive medication timing
If your doctor has approved preventive medication for predictable triggers, a confirmed forecast drop can give you a 12–24 hour window to take it preemptively.
Avoid stacking triggers
On high-risk weather days, be more careful with secondary triggers: caffeine changes, skipped meals, dehydration, poor sleep, or alcohol.
Track your personal threshold
Population-level thresholds (5+ hPa drop = elevated risk) are averages. Your personal threshold may be higher or lower. Track your attacks alongside weather data to find your number.
