Today's barometric pressure in Mobile, 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 Mobile...
Mobile receives more rainfall than almost any US city outside the Pacific Northwest, driven by persistent Gulf moisture. The city's coastal Alabama location means high baseline humidity and frequent thunderstorms, each carrying measurable pressure shifts.
Worst season for migraines: January. Mobile is the wettest major city in the contiguous US, averaging over 65 inches of rain annually. Winter fronts bring most of its pressure drops, peaking in January, when 43% of days see a 5 hPa drop. A hurricane can bring a severe single drop, but summer is otherwise very steady, 1% of days or fewer in each summer month.
Common triggers in Mobile: Gulf hurricane and tropical storm pressure drops, persistent Gulf humidity above 85%, spring severe thunderstorm squall lines. Mobile sits at the head of Mobile Bay where the Mobile and Tensaw rivers create a vast delta ecosystem. This water-surrounded geography means humidity is inescapable, and the bay acts as a warm water heat source that enhances storm development. Mobile's Gulf Coast position makes it one of the most hurricane-vulnerable cities in the US, and even distant Gulf tropical systems can produce measurable pressure changes days before arrival.
Typical pressure: Mobile 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 3-9 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Mobile ranks #87 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Mobile weather trigger migraines?
Yes. Mobile experiences 3-9 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Gulf hurricane and tropical storm pressure drops, persistent Gulf humidity above 85%, spring severe thunderstorm squall lines.
