Today's barometric pressure in Dayton, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Dayton's Miami Valley location in western Ohio is a natural corridor for weather systems moving through the Ohio River basin. The city's flat terrain offers no protection from frontal passages, making barometric changes sharp and sudden.
Worst season for migraines: March through May and October through December. Dayton's Great Miami River valley position places it in the Ohio Valley storm track where weather systems intensify as they cross the region. Spring severe weather and fall cold front passages produce the most significant pressure swings across the flat western Ohio landscape.
Common triggers in Dayton: Ohio Valley frontal passage pressure drops, Great Miami River valley humidity and fog events, spring severe thunderstorm outflow boundaries. Dayton sits at the confluence of the Great Miami, Stillwater, Mad, and Wolf Creek rivers, making it one of the most river-influenced cities in Ohio. These waterways create a broad valley that channels weather systems and traps moisture during inversions. The flat terrain of the western Ohio till plains offers no shelter from approaching weather, and the convergence of multiple river valleys creates localized fog and humidity events that can differ from conditions just a few miles away.
Typical pressure: Dayton averages 990 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 13-20 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Dayton weather trigger migraines?
Yes. Dayton experiences 13-20 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Ohio Valley frontal passage pressure drops, Great Miami River valley humidity and fog events, spring severe thunderstorm outflow boundaries.
What time of year are migraines worst in Dayton?
In Dayton 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 Dayton?
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 Dayton'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 Dayton's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
