48-hour migraine risk based on barometric pressure, humidity, and temperature changes in New Haven.
New Haven sits on Long Island Sound, partially sheltered by the island itself from open Atlantic swell and wind. Pressure averages 1014 hPa, but swings still reach 15 hPa because coastal storms track directly overhead regardless of that shelter.
Worst season for migraines: February, December and January. Winter coastal systems bring the year's steepest changes. The Sound moderates temperature enough that these often arrive as rain or mixed precipitation rather than snow, which does nothing to reduce the barometric component.
Common triggers in New Haven: coastal systems tracking over the Sound, summer sea breeze convergence, Quinnipiac valley cold air drainage. Long Island acts as a breakwater, so New Haven's marine influence is gentler than an open-ocean city at the same latitude. What the Sound does provide is a persistent moisture source and a sea breeze that develops most summer afternoons. The city also sits at the mouth of the Quinnipiac valley, which channels cold air down from the interior.
Typical pressure: New Haven averages 1014 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 994 hPa. Swings of 7-15 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can New Haven weather trigger migraines?
Yes. New Haven experiences 7-15 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include coastal systems tracking over the Sound, summer sea breeze convergence, Quinnipiac valley cold air drainage.
What time of year are migraines worst in New Haven?
In New Haven the most barometrically volatile stretch of the year falls in February, December and January. 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 New Haven?
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 New Haven's weather conditions over time.
