Today's barometric pressure in Asheville, 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 Asheville...
Asheville's 2,100-foot elevation in the Blue Ridge Mountains creates a mountain weather environment unique among Southern cities. Orographic lifting produces frequent cloud formation and precipitation, while mountain waves create localized pressure oscillations.
Worst season for migraines: December through March. Asheville's mountain valley location creates complex weather patterns as systems interact with the Blue Ridge and Great Smoky Mountains. Cold air damming from the east and orographic enhancement from the west produce pressure events that differ significantly from both the coast and the interior lowlands.
Common triggers in Asheville: Blue Ridge orographic storm enhancement, French Broad River valley temperature inversions, rapid elevation-related pressure changes during mountain travel. Asheville sits at 2,100 feet in the French Broad River basin, surrounded by some of the highest peaks in the eastern US. The mountains create rain shadow effects, orographic precipitation enhancement, and valley inversions that trap cold, moist air. Residents traveling between Asheville and nearby communities routinely cross elevation changes of 2,000-4,000 feet, exposing them to significant pressure differentials during routine daily activities.
Typical pressure: Asheville averages 943 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 930 hPa. Swings of 4-10 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Asheville ranks #64 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Asheville weather trigger migraines?
Yes. Asheville experiences 4-10 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Blue Ridge orographic storm enhancement, French Broad River valley temperature inversions, rapid elevation-related pressure changes during mountain travel.
What time of year are migraines worst in Asheville?
In Asheville the most barometrically volatile stretch of the year falls in December 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 Asheville?
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 Asheville 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.
