48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Rochester.
Rochester sits at 312 metres on southeastern Minnesota's rolling uplands, where the Zumbro River has cut into the plateau. Baseline pressure near 978 hPa reflects that elevation, and cold-season swings reach 14 hPa.
Worst season for migraines: December, February and March. December is the sharpest month here, when the first sustained Arctic air of the season collides with moisture still lingering from autumn. That pattern repeats through late winter as each successive outbreak arrives colder than the last.
Common triggers in Rochester: Arctic outbreaks meeting residual autumn moisture, Driftless terrain cold air pooling, long-duration pressure declines ahead of Colorado lows. Southeastern Minnesota sits at the edge of the Driftless Area, terrain the glaciers never flattened, so the landscape is unusually broken for the upper Midwest. River valleys hold cold air while the uplands stay several degrees warmer. Winter storms tracking from the southwest bring the region's heaviest snow, and their approach is often preceded by a long slow pressure decline.
Typical pressure: Rochester averages 978 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 961 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.
Can Rochester weather trigger migraines?
Yes. Rochester experiences 6-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Arctic outbreaks meeting residual autumn moisture, Driftless terrain cold air pooling, long-duration pressure declines ahead of Colorado lows.
What time of year are migraines worst in Rochester?
In Rochester the most barometrically volatile stretch of the year falls in December, February and March. 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 Rochester?
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 Rochester's weather conditions over time.
