Today's barometric pressure in Jacksonville, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Jacksonville's Atlantic coast position exposes it to tropical systems and sea breeze fronts that create daily pressure fluctuations. Summer thunderstorms roll through almost every afternoon, each bringing a small but measurable pressure shift.
Worst season for migraines: June through November. Jacksonville's hurricane season vulnerability is amplified by its position on the northeast Florida coast, where tropical systems curving northward often make landfall or pass nearby. Summer sea-breeze thunderstorms develop almost daily along the St. Johns River corridor.
Common triggers in Jacksonville: tropical system pressure drops along the Atlantic coast, daily sea-breeze thunderstorm convergence, high humidity combined with summer heat above 95 degrees. Jacksonville's sprawling metro area spans the lower St. Johns River basin, where the wide river and nearby Atlantic Ocean create competing sea-breeze and river-breeze convergence zones. These convergence boundaries trigger afternoon thunderstorms that can affect one side of the city while the other remains clear, making pressure changes hyperlocal.
Typical pressure: Jacksonville 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 8-22 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Jacksonville weather trigger migraines?
Yes. Jacksonville experiences 8-22 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include tropical system pressure drops along the Atlantic coast, daily sea-breeze thunderstorm convergence, high humidity combined with summer heat above 95 degrees.
What time of year are migraines worst in Jacksonville?
In Jacksonville the most barometrically volatile stretch of the year falls in June through November. That is when weather is most likely to play a part, if weather is a trigger for you at all.
How do I track migraine triggers in Jacksonville?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and Jacksonville's weather conditions over time.

Is it really the weather?
Weather gets blamed for a lot of migraines, but it's hard to know if it's really behind yours. The MigrAid app saves the barometric pressure with every migraine you log, so after a few weeks you can see whether Jacksonville's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
