One of the most stable barometric pressure profiles in the US, typically ranging 1010–1018 hPa year-round. The primary risk window is October–December when Santa Ana wind events bring sudden pressure changes, low humidity under 10%, and elevated particulate — a combination many migraineurs find highly triggering.
Seasonal Pattern
Highest risk: October–December during Santa Ana wind season. Otherwise among the most stable major US cities.
Managing Weather-Triggered Migraines in Los Angeles
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.
