Today's barometric pressure in Orlando, 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 Orlando...
Orlando's inland Florida location means less ocean moderation than coastal cities but more afternoon thunderstorm activity. The sea breeze convergence zone that sets up over central Florida nearly every summer day creates predictable but persistent pressure changes.
Worst season for migraines: January. Orlando's inland position means east and west coast sea breezes converge over the city nearly every summer afternoon, but those storms barely move pressure, 1% of days or fewer in each summer month. Most pressure drops come with winter fronts, peaking in January, when 37% of days see a 5 hPa drop. A hurricane can bring a severe single drop.
Common triggers in Orlando: daily sea-breeze convergence thunderstorms, tropical storm and hurricane pressure drops, persistent humidity above 80% from May through October. Orlando sits on the central Florida plateau surrounded by more than 100 named lakes, which add moisture to the already humid subtropical air. The city's inland position means both the Atlantic and Gulf sea breezes converge overhead, creating a daily thunderstorm corridor that runs directly through the metro. This predictable pattern means small pressure changes on most summer afternoons.
Typical pressure: Orlando 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 990 hPa. Swings of 3-7 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Orlando ranks #91 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Orlando weather trigger migraines?
Yes. Orlando experiences 3-7 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include daily sea-breeze convergence thunderstorms, tropical storm and hurricane pressure drops, persistent humidity above 80% from May through October.
What time of year are migraines worst in Orlando?
In Orlando the most barometrically volatile stretch of the year falls in January. 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 Orlando?
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 Orlando 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.
