48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Manchester.
Manchester sits in the Merrimack Valley about 80 kilometres from the Atlantic, close enough for coastal storms and far enough inland for continental cold. Its 17 hPa swing range is among the widest measured in this dataset.
Worst season for migraines: February, December and January. Southern New Hampshire sits at the pivot point where coastal storms decide whether to track out to sea or up over land. That uncertainty means the city sees the full range of outcomes, from glancing blows to direct hits, within the same season.
Common triggers in Manchester: Gulf of Maine storm intensification, Merrimack Valley cold air drainage, sharp post-storm pressure rebound. Air funnels between the White Mountains and the coast along the Merrimack Valley, and Manchester sits where that corridor is narrowest. Storms strengthening over the Gulf of Maine pull cold air down the valley behind them, so the temperature and pressure recovery after a storm can be as abrupt as the storm itself.
Typical pressure: Manchester averages 1006 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 985 hPa. Swings of 7-17 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Manchester weather trigger migraines?
Yes. Manchester experiences 7-17 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Gulf of Maine storm intensification, Merrimack Valley cold air drainage, sharp post-storm pressure rebound.
What time of year are migraines worst in Manchester?
In Manchester 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 Manchester?
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 Manchester's weather conditions over time.
