Today's barometric pressure in Augusta, 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 Augusta...
Augusta's fall line location between the Piedmont and Coastal Plain creates a natural weather boundary. The city's humid subtropical climate means year-round thunderstorm potential, with spring bringing the most volatile pressure conditions.
Worst season for migraines: December through March. Augusta's Savannah River valley position at the Fall Line creates conditions where Piedmont storms intensify as they meet the terrain transition. Winter fronts drive the pressure drops from December through March, peaking in January, when 50% of days see a 5 hPa drop. Spring storms and fall tropical remnants add occasional events, but summer months see a 5 hPa drop on 8% of days or fewer.
Common triggers in Augusta: Savannah River valley humidity concentration, spring squall line passages across the Piedmont, tropical remnant moisture from Atlantic hurricanes. Augusta sits on the Savannah River at the Fall Line, where the hilly Piedmont transitions to the flat coastal plain. This geological boundary concentrates moisture along the river corridor and creates terrain-influenced weather effects. The city's position 150 miles inland means tropical systems arrive weakened but still carry significant moisture and residual pressure impacts. The broad Savannah River floodplain and surrounding pine forests maintain high humidity through the warm season.
Typical pressure: Augusta averages 1014 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 999 hPa. Swings of 4-11 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Augusta ranks #70 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Augusta weather trigger migraines?
Yes. Augusta experiences 4-11 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Savannah River valley humidity concentration, spring squall line passages across the Piedmont, tropical remnant moisture from Atlantic hurricanes.
What time of year are migraines worst in Augusta?
In Augusta 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 Augusta?
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 Augusta 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.
