Today's barometric pressure in Charleston, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Charleston's Kanawha Valley location in the heart of the Appalachians creates complex pressure patterns as weather systems navigate the mountainous terrain. Valley inversions trap moisture and pollution, adding environmental triggers to barometric changes.
Worst season for migraines: March through May and October through December. Charleston's Kanawha Valley position in the central Appalachians traps and channels weather systems through narrow river corridors. Spring and fall frontal passages intensify as they cross the mountains, and the valley geography creates persistent inversions that hold moisture and pollutants close to the surface.
Common triggers in Charleston: Kanawha Valley temperature inversions trapping industrial emissions, Appalachian Mountain orographic storm enhancement, rapid frontal passages through the narrow river valley. Charleston sits at 600 feet where the Elk River meets the Kanawha River, in a narrow valley carved through the Appalachian Plateau. The surrounding mountains rise 1,000+ feet above the river, creating a confined geography that traps air, amplifies weather events, and creates inversions. The industrial Kanawha Valley's chemical plants have historically contributed air quality concerns that compound weather-related migraine triggers during stagnant air events.
Typical pressure: Charleston averages 995 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 980 hPa. Swings of 12-18 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Charleston weather trigger migraines?
Yes. Charleston experiences 12-18 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Kanawha Valley temperature inversions trapping industrial emissions, Appalachian Mountain orographic storm enhancement, rapid frontal passages through the narrow river valley.
What time of year are migraines worst in Charleston?
In Charleston the most barometrically volatile stretch of the year falls in March through May and October through December. That is when weather is most likely to play a part, if weather is a trigger for you at all.
How do I track migraine triggers in Charleston?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and Charleston's weather conditions over time.

Is it really the weather?
Weather gets blamed for a lot of migraines, but it's hard to know if it's really behind yours. The MigrAid app saves the barometric pressure with every migraine you log, so after a few weeks you can see whether Charleston's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
