Today's barometric pressure in Wilmington, 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 Wilmington...
Wilmington sits at the fall line where the Piedmont drops to the coastal plain, at the head of Delaware Bay. Pressure averages 1013 hPa, and its position on the mid-Atlantic storm track means most systems moving up the coast pass directly overhead.
Worst season for migraines: February, January and December. Running almost straight over the city, the mid-Atlantic winter storm track delivers a high frequency of passages rather than a few extreme ones. Each produces a measurable step in the barometer.
Common triggers in Wilmington: Appalachian cold air damming, freezing rain from wedge events, high frequency mid-Atlantic storm passage. Cold air damming is the defining regional pattern: cold air wedges south along the eastern side of the Appalachians and gets trapped beneath warmer air arriving from the coast. The result is prolonged periods of freezing rain and a pressure pattern that changes slowly over days. Delaware sits in the heart of the damming zone.
Typical pressure: Wilmington averages 1013 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 995 hPa. Swings of 7-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Wilmington is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Wilmington weather trigger migraines?
Yes. Wilmington experiences 7-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include Appalachian cold air damming, freezing rain from wedge events, high frequency mid-Atlantic storm passage.
What time of year are migraines worst in Wilmington?
In Wilmington the most barometrically volatile stretch of the year falls in February, January 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 Wilmington?
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 Wilmington 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.
