Today's barometric pressure in Huntsville, 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 Huntsville...
Huntsville sits in the Tennessee Valley at the southern tip of the Cumberland Plateau, with Monte Sano rising directly east of downtown. Pressure averages 994 hPa at 193 metres, and the surrounding ridges shape how weather reaches the city.
Worst season for migraines: January through March. North Alabama's severe weather season runs earlier than the plains, peaking from late winter into early spring. A secondary autumn season in November adds a second period of frequent frontal passage.
Common triggers in Huntsville: squall line passages through the valley, dual spring and autumn severe seasons, plateau edge orographic cloud and lift. Northern Alabama records among the highest tornado frequencies in the country, and the associated squall lines produce abrupt pressure changes as they cross. Terrain matters here more than the flat imagery suggests: the plateau edge and the valley floor experience storms differently, and low cloud often hangs on Monte Sano while the valley stays clear.
Typical pressure: Huntsville averages 994 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 983 hPa. Swings of 5-9 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Huntsville is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Huntsville weather trigger migraines?
Yes. Huntsville experiences 5-9 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include squall line passages through the valley, dual spring and autumn severe seasons, plateau edge orographic cloud and lift.
What time of year are migraines worst in Huntsville?
In Huntsville the most barometrically volatile stretch of the year falls in January through March. 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 Huntsville?
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 Huntsville 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.
