How weather affects migraine
Not every weather factor hits every condition the same way. These are the inputs our Migraine scoring model weighs most heavily — and in San Francisco (West Coast), they interact with the local climate pattern: Seattle, San Francisco, and Los Angeles — Pacific coast weather trends and body-forecast scores.
Barometric pressure changes
35% of scoreBarometric pressure drops are one of the most consistently reported migraine triggers, likely affecting intracranial pressure and trigeminal nerve sensitivity.
Daily temperature swings
20% of scoreRapid temperature fluctuations can trigger migraines through neural pathways including trigeminal activation and cortical spreading depression.
Humidity
15% of scoreHigh humidity is associated with migraine onset, possibly through thermoregulatory stress, co-occurring low-pressure systems, and trigeminal nerve activation.
UV exposure
10% of scoreBright sunlight is a potent migraine trigger — up to 67% of migraineurs report light sensitivity. High UV correlates with intense sunlight and glare that activate photosensitivity pathways.
Wind
10% of scoreWarm dry winds (chinook/foehn) have been associated with increased migraine frequency above approximately 38 km/h (24 mph), likely through the rapid pressure and temperature changes they bring.
