Today's barometric pressure in Detroit, 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 Detroit...
Detroit's position between Lakes Huron, Erie, and St. Clair creates complex lake-effect weather patterns. Canadian cold fronts sweep across the lakes and intensify before reaching the city, making winter particularly challenging for migraine sufferers.
Worst season for migraines: October through April. Detroit's position between Lake Erie and Lake Huron subjects it to lake-effect weather from multiple directions. Winter brings persistent cloud cover and frequent pressure oscillations as Alberta Clippers and Great Lakes lows track through the region in rapid succession.
Common triggers in Detroit: dual lake-effect pressure systems from Erie and Huron, persistent winter overcast reducing light exposure, rapid freeze-thaw cycles in spring and fall. Detroit sits on the Detroit River connecting Lake St. Clair to Lake Erie, surrounded by Great Lakes water on multiple sides. This lake-influenced position creates persistent cloud cover from November through March that ranks among the worst in the nation for winter sunlight, compounding pressure-related triggers with light-deprivation effects. The flat terrain of southeast Michigan offers no topographic shelter from incoming frontal systems.
Typical pressure: Detroit averages 994 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 976 hPa. Swings of 7-18 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Detroit ranks #32 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Detroit weather trigger migraines?
Yes. Detroit experiences 7-18 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include dual lake-effect pressure systems from Erie and Huron, persistent winter overcast reducing light exposure, rapid freeze-thaw cycles in spring and fall.
