Today's barometric pressure in Norfolk, 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 Norfolk...
Norfolk's Hampton Roads location at the mouth of the Chesapeake Bay puts it in the direct path of coastal storms and hurricanes. The maritime influence moderates temperature extremes but creates persistent humidity that compounds pressure-related triggers.
Worst season for migraines: November through April. Norfolk's Chesapeake Bay and Atlantic coast exposure makes it vulnerable to nor'easters, tropical systems, and strong coastal lows. The bay-ocean interaction creates local weather effects, and the Hampton Roads harbor geography amplifies moisture-driven pressure variations.
Common triggers in Norfolk: nor'easter and coastal storm pressure drops, Chesapeake Bay moisture surges, tropical remnant rainfall events with sustained low pressure. Norfolk occupies a low-lying peninsula surrounded by the Chesapeake Bay, Hampton Roads harbor, and the Elizabeth River. This water-dominated geography means maritime moisture influences the city from nearly every direction. The bay's relatively warm waters in fall extend tropical storm vulnerability later into the season, and the flat Tidewater terrain offers no natural shelter from incoming weather systems.
Typical pressure: Norfolk averages 1016 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 996 hPa. Swings of 6-16 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Norfolk ranks #51 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
Can Norfolk weather trigger migraines?
Yes. Norfolk experiences 6-16 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include nor'easter and coastal storm pressure drops, Chesapeake Bay moisture surges, tropical remnant rainfall events with sustained low pressure.
What time of year are migraines worst in Norfolk?
In Norfolk the most barometrically volatile stretch of the year falls in November through April. 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 Norfolk?
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 Norfolk 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.
