Today's barometric pressure in Miami, a 48-hour pressure chart, and a risk score for weather-triggered migraine and headache, based on pressure drops, humidity, and temperature changes.
Loading live forecast for Miami...
Miami's tropical climate means consistently high humidity, a baseline migraine trigger for many. Hurricane season from June through November brings the most dramatic pressure events, but daily sea-breeze thunderstorms create smaller pressure fluctuations year-round.
Worst season for migraines: January and February. Miami has very steady pressure. No month reaches the 35% of days our index uses for a trigger season, and even February sees a 5 hPa drop on only 15% of days, usually with a mild winter cold front. A hurricane can bring a severe single drop, but summer sea-breeze storms barely move pressure.
Common triggers in Miami: tropical storm and hurricane pressure drops, persistent humidity above 85%, daily sea-breeze convergence thunderstorms. Miami's tropical maritime climate means humidity is a constant factor, averaging 75-80% year-round. The city's flat terrain and warm ocean waters fuel convective activity nearly daily in summer. During hurricane season, even distant tropical systems can influence local pressure readings days before they arrive.
Typical pressure: Miami averages 1016 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 985 hPa. Swings of 2-5 hPa over 24 hours are typical here, mostly below the 5 hPa drops our index counts.
2026 index: Miami ranks #98 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Miami weather trigger migraines?
It can, though that is rare here. Miami usually sees 2-5 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include tropical storm and hurricane pressure drops, persistent humidity above 85%, daily sea-breeze convergence thunderstorms.
What time of year are migraines worst in Miami?
In Miami the most barometrically volatile stretch of the year falls in January and February. That is when weather is most likely to play a part, if weather is a trigger for you at all. See when migraine weather season starts across the U.S.
Is there a barometric pressure headache forecast for Miami?
This page works as one. Many people call a headache that arrives with a weather change a barometric pressure headache, and this forecast tracks the pressure drops, humidity and temperature swings behind that idea. The score covers the next 24 hours in Miami and the chart shows the next 48. It is built on migraine research, so treat it as a rough guide for other headaches. A sudden, severe headache needs urgent medical care, whatever the weather.
