Today's barometric pressure in Cincinnati, 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 Cincinnati...
Cincinnati's Ohio River valley setting creates a natural weather channel where systems moving east get funneled through the basin. The city's transitional climate zone means frequent alternation between warm Gulf air and cold northern fronts.
Worst season for migraines: November through April. Cincinnati's Ohio River basin creates a natural funnel for weather systems moving through the central Ohio Valley. Winter and early spring fronts produce the most frequent pressure drops, peaking in March, when 60% of days see a 5 hPa drop, as the river valley channels and traps air masses.
Common triggers in Cincinnati: Ohio River valley temperature inversions, spring severe thunderstorm outflows, winter cold air pooling in the river basin. Cincinnati is built into the steep hills of the Ohio River basin, with elevation differences of 400+ feet between the riverfront and surrounding hilltops. The basin traps cold air and river moisture, creating microclimates that vary significantly between neighborhoods. The Mill Creek Valley running north from downtown acts as a secondary weather corridor, and residents at different elevations within the city can experience noticeably different pressure readings.
Typical pressure: Cincinnati averages 986 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 971 hPa. Swings of 6-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Cincinnati ranks #49 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
