Today's barometric pressure in Charlotte, 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 Charlotte...
Charlotte's Piedmont location between the Appalachian Mountains and the coast creates complex weather patterns. Storms that stall against the mountains can cause prolonged low-pressure events that extend migraine triggers over multiple days.
Worst season for migraines: December through April. Charlotte's position east of the Appalachians means cold air damming can lock in overcast, chilly conditions for days. Winter fronts and coastal lows drive the pressure drops from December through April, peaking in February, when 53% of days see a 5 hPa drop, and spring adds squall lines sweeping off the Piedmont. Summer is the calm stretch, at 14% of days or fewer in each summer month.
Common triggers in Charlotte: Appalachian cold air damming events, spring squall lines crossing the Piedmont, tropical remnant moisture from Atlantic hurricanes. Charlotte sits in the Carolina Piedmont at roughly 750 feet elevation, positioned between the Blue Ridge Mountains to the west and the coastal plain to the east. Cold air damming occurs when Arctic air spills over the mountains and becomes trapped against the eastern slopes, creating a persistent cold, damp layer that can linger for days and trigger prolonged migraine episodes.
Typical pressure: Charlotte averages 988 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 974 hPa. Swings of 5-12 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Charlotte ranks #60 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Charlotte weather trigger migraines?
Yes. Charlotte experiences 5-12 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Appalachian cold air damming events, spring squall lines crossing the Piedmont, tropical remnant moisture from Atlantic hurricanes.
