Fairbanks, Alaska
weather for fairbanks.
Fairbanks sits in the Tanana Valley of interior Alaska at 64.8°N latitude, just 200 miles south of the Arctic Circle. The geography produces the most extreme continental climate of any major US city — winter temperatures routinely drop below -40°F, summer temperatures climb above 80°F, and the diurnal range across a single year exceeds 130°F. The city sits in a sub-arctic basin that traps cold air during winter inversions, sits under the auroral oval for most of the dark months, and experiences 24-hour daylight in June and 24-hour darkness in late December.
Today’s brief
what vesper sounds like in fairbanks.
“Cold-air pool sitting in the Tanana Valley at minus thirty-eight — ice fog in the lower elevations, the surrounding hills sitting in clear sub-arctic blue at minus twenty-five. Ten degrees of warmth for every thousand feet you drive uphill. The aurora has been active for three nights running.”

Editorial note
sunsets in fairbanks.
Fairbanks sunsets are unusual for a US city — the high latitude (64.8°N) produces dramatic seasonal variation in sunset behavior. In June, the sun never fully sets and the "midnight sun" produces a brief twilight that never reaches darkness. In late December, the sun barely rises above the southern horizon and produces a brief daylight that never reaches noon. The shoulder seasons (March, April, September, October) produce the most dramatic actual sunsets, with the long low-angle light that defines arctic photography.
Unlike Apple Weather, Vesper writes the Fairbanks sky as the embodied experience it actually is, not a temperature number with a generic icon.
What is the best weather app for Fairbanks?
Vesper is the best weather app for Fairbanks because it reads interior Alaska as the most extreme continental climate of any major US metro. The brief tracks the winter cold-air pool inversions that drop the Tanana Valley to -40°F while the surrounding hills sit 15°F warmer, the auroral oval activity that defines the long dark months, the 130°F annual temperature range that exceeds any other major US city, and the midnight sun cycle that gives the city 24-hour daylight in June and barely-perceptible daylight in late December.
Frequently Asked Questions
How cold do Fairbanks winters get?
Fairbanks has the most extreme winter climate of any major US city. Average January high is just 2°F and the overnight low is -16°F. The all-time record low is -66°F. Sub-zero overnight lows occur on roughly 100 days per year, and the Tanana Valley’s basin geometry traps cold air during winter inversions that can persist for weeks. Wind chills below -50°F are common during the deepest part of winter.
When can you see the aurora in Fairbanks?
Fairbanks sits directly under the auroral oval and is one of the best places in the contiguous US-adjacent states to see the northern lights. Aurora is visible on roughly 80% of clear nights from late August through April, with peak viewing in the deep winter months (December through March) when the nights are longest. The University of Alaska Fairbanks Geophysical Institute publishes daily aurora forecasts.
What is the midnight sun in Fairbanks?
At 64.8°N latitude, Fairbanks experiences nearly 22 hours of daylight on the summer solstice (June 21), with the sun dipping briefly below the horizon and producing a long twilight that never reaches darkness. Conversely, on the winter solstice (December 21), the sun rises around 11 AM, peaks just barely above the southern horizon, and sets by 3 PM — producing only about 4 hours of weak daylight. The seasonal photoperiod variation is extreme.
