Today's barometric pressure in Fairbanks, 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 Fairbanks...
Fairbanks sits in interior Alaska at 136 metres, far from any moderating ocean, and its worst months are January, November and October rather than midwinter alone. Pressure averages 993 hPa with swings reaching 14 hPa.
Worst season for migraines: January, November and October. Autumn is unusually active here, when the transition to winter brings frequent systems before the deep cold settles in and stabilises the pattern. Midwinter often turns quiet, locked under intense high pressure and inversion.
Common triggers in Fairbanks: extreme interior temperature inversions, extraordinary seasonal daylight swings, autumn storm frequency before deep cold sets in. Interior Alaska produces some of the strongest temperature inversions on the planet, with valley floors 20 degrees colder than the hills above. Under those conditions the barometer sits high and flat for weeks. On top of that, the annual daylight swing runs from under four hours in December to nearly 22 in June, a circadian disruption that operates as its own trigger independent of any weather.
Typical pressure: Fairbanks averages 993 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 967 hPa. Swings of 6-14 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Fairbanks is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Fairbanks weather trigger migraines?
Yes. Fairbanks experiences 6-14 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include extreme interior temperature inversions, extraordinary seasonal daylight swings, autumn storm frequency before deep cold sets in.
What time of year are migraines worst in Fairbanks?
In Fairbanks the most barometrically volatile stretch of the year falls in January, November and October. 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 Fairbanks?
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 Fairbanks 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.
