Today's barometric pressure in Baton Rouge, 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 Baton Rouge...
Baton Rouge's Mississippi River location in southern Louisiana brings relentless humidity and Gulf moisture. The city averages over 60 inches of rain annually, with each storm system bringing pressure fluctuations that make it a difficult climate for migraine sufferers.
Worst season for migraines: January and February. Baton Rouge's Mississippi River position and Gulf proximity mean a hurricane can bring a severe single drop. The frequent drops come with winter fronts in January and February, peaking in January, when 40% of days see a 5 hPa drop. Spring and fall squall lines track along the Mississippi Valley, and summer pressure is very steady, 1% of days or fewer in each summer month.
Common triggers in Baton Rouge: Gulf tropical storm and hurricane pressure drops, Mississippi River corridor humidity and thunderstorm development, persistent subtropical humidity above 80%. Baton Rouge sits on river bluffs overlooking the Mississippi River, 80 miles upstream from the Gulf of Mexico. The river's influence keeps humidity high year-round, and the surrounding lowland swamps and bayous act as moisture reservoirs. The city's position between the Gulf Coast and the lower Mississippi Valley means it catches both tropical systems from the south and severe weather from the west, making it one of the most weather-active metros in the Southeast.
Typical pressure: Baton Rouge 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 3-10 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Baton Rouge ranks #81 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
