Today's barometric pressure in Louisville, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Louisville's Ohio River valley location traps moisture and creates frequent temperature inversions. The city's weather can change dramatically within hours as fronts move through the relatively flat terrain, catching migraine sufferers off guard.
Worst season for migraines: March through May and October through December. Louisville's Ohio River valley position puts it in the path of frequent frontal passages year-round. Spring brings the most volatility as warm Gulf air surges north and collides with lingering cold air funneled through the river valley from the Great Lakes region.
Common triggers in Louisville: Ohio River valley cold air channeling, spring severe thunderstorm outflows, autumn temperature inversions trapping river valley humidity. Louisville straddles the Falls of the Ohio where the river drops 26 feet, creating a natural boundary between the Bluegrass region and the Southern Indiana lowlands. The river valley traps moisture and pollution, creating frequent temperature inversions that hold triggers close to the surface. The Knobs region south of the city adds terrain complexity that can enhance storm development.
Typical pressure: Louisville averages 1000 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 986 hPa. Swings of 12-20 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Louisville weather trigger migraines?
Yes. Louisville experiences 12-20 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Ohio River valley cold air channeling, spring severe thunderstorm outflows, autumn temperature inversions trapping river valley humidity.
What time of year are migraines worst in Louisville?
In Louisville 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.

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 Louisville's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
