Pressure and weather in Broussard

Broussard lies in Lafayette Parish in south-central Louisiana, on the flat prairie and bayou country of Acadiana between the Vermilion River and the Atchafalaya Basin, roughly forty miles from the Gulf coast with nothing but marsh in between. There is no elevation and no shelter, and the Gulf is effectively next door. Barometric pressure here follows the subtropical pattern with an unusually active frontal season layered on top. From late May through September the barometer is high, flat and monotonous under the Bermuda high, with drenching afternoon thunderstorms firing along the sea breeze and moving inland, none of which shifts current barometric pressure much at all. The exception is tropical: from August through early October a Gulf system approaching the Louisiana coast produces the deepest and longest pressure fall in the local climate, and this stretch of coast has seen enough landfalls in recent decades that the reading itself is treated as a serious signal rather than a curiosity. The cool season is entirely different in character. From November through March, strong cold fronts sweep in from Texas every few days, often preceded by an organized squall line with a sharp pressure fall and a violent wind shift, followed by a firm rise and a dramatic drop in dewpoint as continental air replaces Gulf air. Late winter and early spring bring the region's severe weather peak, when those same boundaries can spin up tornadoes. A barometric pressure forecast for Broussard matters most from February through April and again during hurricane season.

What this means for you

Can barometric pressure cause headaches? South Louisiana pairs its pressure changes with enormous humidity swings, since a front can cut the dewpoint by twenty degrees in an hour. For many weather-sensitive people the two together are harder than either alone. Use this barometric pressure forecast with Pressure Pal as a headache tracking app to see pressure change today and get warning before the next Gulf front or tropical system arrives.
