Today's barometric pressure in Columbus, 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 Columbus...
Columbus sits on the Chattahoochee River at the fall line, where the Piedmont drops to the coastal plain. Pressure averages 1009 hPa, and the river valley marks a genuine climatic boundary between two distinct regions.
Worst season for migraines: January through March. Cool months deliver what frontal activity the area sees, with each passage producing a clear barometric step. From June onward the pattern becomes convective, with afternoon storms forming most days along the river corridor.
Common triggers in Columbus: fall line storm intensification, daily summer convection along the Chattahoochee, weakened Gulf systems reaching inland. Fall line cities sit where rivers drop from hard Piedmont rock onto soft coastal sediment, and that geological boundary tends to coincide with a weather boundary too. Storms frequently intensify or dissipate as they cross it. Columbus also sits far enough inland that Gulf systems arrive weakened but far enough south that Appalachian cold rarely reaches full strength.
Typical pressure: Columbus averages 1009 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 998 hPa. Swings of 5-9 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Columbus is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Columbus weather trigger migraines?
Yes. Columbus experiences 5-9 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include fall line storm intensification, daily summer convection along the Chattahoochee, weakened Gulf systems reaching inland.
What time of year are migraines worst in Columbus?
In Columbus the most barometrically volatile stretch of the year falls in January 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 Columbus?
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 Columbus 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.
