Today's barometric pressure in Duluth, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Duluth's position at the western tip of Lake Superior creates one of the most dramatically weather-affected environments in the US. The lake generates its own pressure systems, and the city's northern latitude means long, intense storm seasons.
Worst season for migraines: September through May. Duluth's western Lake Superior shoreline exposes it to powerful fall and winter storms that develop over the lake. The Lake Superior basin generates its own intense low-pressure systems, sometimes rivaling coastal nor'easters in pressure drops. Spring ice breakup creates additional atmospheric instability.
Common triggers in Duluth: Lake Superior gale-force storm pressure drops, extreme cold creating vascular constriction, persistent winter cloud cover from lake-effect moisture. Duluth cascades from 800-foot bluffs down to the Lake Superior waterfront, creating dramatic elevation differences within city limits. The lake's massive cold-water surface moderates coastal temperatures but generates intense storms, especially in November when temperature differentials between the water and Arctic air are greatest. The city's position at the western tip of the lake means it catches weather from the full fetch of this inland sea, the largest freshwater lake by surface area in the world.
Typical pressure: Duluth 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 972 hPa. Swings of 18-30 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Duluth weather trigger migraines?
Yes. Duluth experiences 18-30 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Lake Superior gale-force storm pressure drops, extreme cold creating vascular constriction, persistent winter cloud cover from lake-effect moisture.
What time of year are migraines worst in Duluth?
In Duluth the most barometrically volatile stretch of the year falls in September through May. 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 Duluth?
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 Duluth'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 Duluth's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
