LiveWeather & Migraines in San Antonio
Strong frontal systems — particularly "Blue Northers" — can drop temperatures 20°C and pressure 10+ hPa within hours during fall and winter. Summer heat domes maintain stable but unusually low pressure conditions that can persist for weeks.
Seasonal Pattern
Highest risk: October–February during Blue Norther frontal passages. Summer heat domes also create persistent low-pressure periods.
Managing Weather-Triggered Migraines in San Antonio
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.
