Today's barometric pressure in Worcester, 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 Worcester...
Worcester sits at 147 metres on the high ground of central Massachusetts, the highest of New England's major cities. That elevation puts baseline pressure near 997 hPa and produces swings up to 16 hPa, wider than Boston an hour to the east.
Worst season for migraines: February, December and January. Interior New England sits far enough from the coast that nor'easters arrive as snow rather than rain, and far enough inland that Arctic air settles in behind them. Both halves of that sequence register on the barometer.
Common triggers in Worcester: elevation-driven snow when the coast sees rain, slow-departing nor'easters over the hills, Arctic air settling behind coastal storms. Worcester's hills put it several hundred feet above the Boston basin, which regularly means snow here when the coast gets rain. Storms tracking up the coast interact with that elevation to produce heavier precipitation and a slower departure, extending the low-pressure period well beyond what coastal cities experience from the same system.
Typical pressure: Worcester averages 997 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 977 hPa. Swings of 7-16 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Worcester is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Worcester weather trigger migraines?
Yes. Worcester experiences 7-16 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include elevation-driven snow when the coast sees rain, slow-departing nor'easters over the hills, Arctic air settling behind coastal storms.
What time of year are migraines worst in Worcester?
In Worcester 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. See when migraine weather season starts across the U.S.
Is there a barometric pressure headache forecast for Worcester?
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 Worcester 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.
