Migraine weather today
How stable is barometric pressure in your area today?
For many migraine sufferers, it isn't the weather itself that hurts — it's the change. Rapid swings in barometric pressure, especially the fast drops ahead of storm systems, show up again and again in migraine trigger research. The absolute pressure reading matters far less than how quickly it's moving.
This tool tracks pressure stability for 500 US cities: the fastest change in any 6-hour window, the total swing across the last 48 hours, and the direction over the next 24. A calm day reads as low risk; a volatile one is your heads-up to plan around it.
It's weather data, not a medical prediction — individual triggers vary widely, and pressure is only one of many. But if you already know pressure affects you, checking your city takes five seconds.

How it works
This tool shows how much barometric pressure has changed over the past 48 hours and is forecast to change in the next 24 hours. Rapid pressure swings are associated with migraine onset in some people — but pressure is just one of many possible triggers, and individual sensitivity varies widely. This is weather data, not a medical prediction. It does not tell you whether you will get a migraine; it tells you whether pressure conditions are calm or volatile. Think of it like a heads-up for people who already know pressure affects them.
