Today's barometric pressure in Lansing, 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 Lansing...
Lansing sits in the middle of Michigan's lower peninsula, roughly equidistant from Lake Michigan and Lake Huron. Pressure averages 985 hPa with swings reaching 15 hPa, wide for an inland city and a consequence of sitting between two large water bodies.
Worst season for migraines: February, March and December. The cold season delivers a mix of clipper systems from the northwest and larger lows tracking through the lakes. Mid-Michigan's position means it can receive precipitation from either lake depending on wind direction, without being reliably in either snow belt.
Common triggers in Lansing: frequent Alberta Clipper passages, dual lake moisture depending on wind direction, sharp wind shifts with fast-moving lows. Alberta Clippers, fast-moving low pressure systems that drop southeast out of Canada, cross mid-Michigan regularly through winter. They bring modest snow but sharp pressure changes and strong wind shifts, moving through in under a day. Their frequency is what distinguishes the mid-Michigan pattern from the lakeshore, where slower lake-effect events dominate.
Typical pressure: Lansing averages 985 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 6-15 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Lansing is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Lansing weather trigger migraines?
Yes. Lansing experiences 6-15 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include frequent Alberta Clipper passages, dual lake moisture depending on wind direction, sharp wind shifts with fast-moving lows.

In Lansing the most barometrically volatile stretch of the year falls in February, March and December. That is when weather is most likely to play a part, if weather is a trigger for you at all. See when migraine weather season starts across the U.S.
Is there a barometric pressure headache forecast for Lansing?
This page works as one. Many people call a headache that arrives with a weather change a barometric pressure headache, and this forecast tracks the pressure drops, humidity and temperature swings behind that idea. The score covers the next 24 hours in Lansing and the chart shows the next 48. It is built on migraine research, so treat it as a rough guide for other headaches. A sudden, severe headache needs urgent medical care, whatever the weather.
