Today's barometric pressure in Madison, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Madison's isthmus location between two lakes creates localized weather effects. The city's position in southern Wisconsin means full exposure to Midwest weather volatility, with Alberta Clippers and Gulf moisture both reaching the area.
Worst season for migraines: October through April. Madison's isthmus position between Lakes Mendota and Monona creates unique microclimate effects that compound broader weather patterns. Alberta Clippers and polar vortex events produce extreme pressure swings in winter, while spring brings volatile conditions as lake ice breaks up and modifies the local atmosphere.
Common triggers in Madison: Alberta Clipper rapid pressure drops, lake-modified wind and pressure patterns from the Yahara chain lakes, extreme winter cold creating vascular constriction. Madison is built on a narrow isthmus between two sizable lakes in the Yahara River chain, with two additional lakes nearby. These water bodies moderate temperatures but create local wind and moisture effects that differentiate Madison's microclimate from surrounding farmland. The lakes delay spring warming and extend fall warmth, shifting the city's seasonal patterns relative to nearby areas and creating local pressure differentials on breezy days.
Typical pressure: Madison averages 984 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 966 hPa. Swings of 16-24 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Madison weather trigger migraines?
Yes. Madison experiences 16-24 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Alberta Clipper rapid pressure drops, lake-modified wind and pressure patterns from the Yahara chain lakes, extreme winter cold creating vascular constriction.
What time of year are migraines worst in Madison?
In Madison the most barometrically volatile stretch of the year falls in October through April. 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 Madison?
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 Madison'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 Madison's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
