Today's barometric pressure in Boston, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Boston sees significant barometric pressure swings in spring and fall, making it one of the more migraine-trigger-prone cities in the Northeast. Nor'easters can drop pressure rapidly over hours, and the city's coastal position amplifies the impact of Atlantic weather systems.
Worst season for migraines: September through April. Boston's extended storm season runs from fall nor'easters through winter blizzards and into spring coastal lows. The city averages 10-15 significant pressure events per season, with nor'easters capable of dropping pressure 20+ hPa over 24 hours.
Common triggers in Boston: nor'easter pressure bombs, rapid freeze-thaw temperature cycles, coastal fog and humidity shifts. Boston's harbor location amplifies the impact of Atlantic storms. The city sits at the convergence of the cold Labrador Current and warm Gulf Stream influences, creating sharp temperature gradients offshore that fuel intense storm development right at the city's doorstep.
Typical pressure: Boston averages 1015 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 993 hPa. Swings of 15-22 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Boston weather trigger migraines?
Yes. Boston experiences 15-22 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include nor'easter pressure bombs, rapid freeze-thaw temperature cycles, coastal fog and humidity shifts.
What time of year are migraines worst in Boston?
In Boston the most barometrically volatile stretch of the year falls in September 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 Boston?
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 Boston'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 Boston's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
