Today's barometric pressure in Atlanta, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Atlanta's position at the southern end of the Appalachian foothills creates orographic effects that influence local pressure patterns. The city's warm, humid climate means thunderstorm activity nearly year-round, with each storm bringing measurable pressure shifts.
Worst season for migraines: March through May and October through November. Atlanta's spring severe weather season brings powerful squall lines with rapid pressure drops. Fall brings secondary volatility as the jet stream dips southward and frontal passages become more frequent across the Piedmont region.
Common triggers in Atlanta: spring squall line passages, summer heat dome humidity, rapid autumn frontal changes. Atlanta's 1,000-foot elevation in the foothills of the Appalachians gives it slightly lower baseline pressure than coastal Southern cities. The city's position at the southern end of the mountain chain creates orographic effects that can intensify storms and pressure changes as systems move through.
Typical pressure: Atlanta averages 980 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 969 hPa. Swings of 10-18 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Atlanta weather trigger migraines?
Yes. Atlanta experiences 10-18 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include spring squall line passages, summer heat dome humidity, rapid autumn frontal changes.
What time of year are migraines worst in Atlanta?
In Atlanta the most barometrically volatile stretch of the year falls in March through May and October through November. 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 Atlanta?
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 Atlanta'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 Atlanta's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
