Today's barometric pressure in Greensboro, 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 Greensboro...
Greensboro sits at 266 metres in the Piedmont Triad, midway between the Appalachians and the coast. Pressure averages 987 hPa with swings reaching 11 hPa, and the city's inland position exposes it to both mountain and coastal weather.
Worst season for migraines: January through March. Winter systems arriving from either direction make the cool months the most variable stretch. Ice storms are a particular risk here, because the Piedmont often sits exactly where warm air overruns a shallow cold layer at the surface.
Common triggers in Greensboro: overrunning ice storm setups, cold air damming against the Blue Ridge, slow-building pressure changes over multiple days. Central North Carolina is a classic transition zone, close enough to the mountains for cold air damming and close enough to the coast for Atlantic moisture. When those two combine, the result is freezing rain rather than snow, and the setup can persist for a day or more. Pressure during these events changes slowly, which is why the triggers often build gradually.
Typical pressure: Greensboro averages 987 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 973 hPa. Swings of 6-11 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Greensboro is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Greensboro weather trigger migraines?
Yes. Greensboro experiences 6-11 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include overrunning ice storm setups, cold air damming against the Blue Ridge, slow-building pressure changes over multiple days.
What time of year are migraines worst in Greensboro?
In Greensboro the most barometrically volatile stretch of the year falls in January through March. 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 Greensboro?
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 Greensboro 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.
