Does Weather Cause Migraines?

Weather changes may trigger migraine attacks in some people, although estimates vary and research has not established a consistent effect for everyone. Possible weather-related triggers include changes in barometric pressure, humidity, temperature, and storm conditions. Research findings are mixed, and no single pressure-change threshold reliably predicts migraine attacks. Bright sunlight, high winds, and seasonal changes also contribute to weather-related headaches. Researchers do not yet fully understand how weather changes might contribute to migraine attacks, and suspected mechanisms remain under study. Keeping a headache diary that tracks weather patterns alongside your symptoms can help identify your specific meteorological triggers and improve prevention strategies.
