Fairbanks winter weather, and what to wear

January averages a low of −17°F (−27°C); by March the average high is back up to 25°F (−4°C), which is the easiest month to stand outside at night.

Key takeaways

  • Fairbanks is inland, so its winter is dry and very cold, unlike Iceland's mild, wet winter, and the payoff is clear, starry nights.
  • The airport averages about 7 days a year at −40°F or colder, but it swings widely: 26 days in 2012, none in 2016.
  • Dress in wool or synthetic layers, never cotton, topped with an expedition-weight down parka, insulated snow pants, and mittens over thin liner gloves.
  • Keep phone and spare camera batteries in an inside pocket, and leave the camera in a sealed bag indoors until it warms up.

What the cold is like

In short Dry and sharp: from December to February average lows run from −11°F to −17°F, and your breath freezes on your scarf and eyelashes.

From December to February, average lows at the airport run from −11°F to −17°F. At those temperatures the air feels dry and sharp, and your breath freezes on your scarf and eyelashes.

Standing still is what gets you

An hour watching the northern sky at −20°F is colder than a brisk walk at the same temperature.

The −40 question

Then there's −40, where Fahrenheit and Celsius meet. It swings wildly from year to year, so plan for it, but don't expect it.

Why the hills can be milder

Fairbanks sits in a valley, and on still, cold nights the coldest air settles at the bottom. The hills around town can be milder than the airport reading, and low spots colder.

How dark it gets

In short Very dark: the shortest day has 3 h 41 min of sun, and a little over six hours of usable light with twilight either side.

By late February and March the days are long again, but the nights are still properly dark for the aurora, which is one reason we recommend those months. The month-by-month aurora odds are on best time to see the northern lights in Alaska.

What to wear for a night outside

Explore Fairbanks' advice is "layers, layers, layers", in wool, synthetics and fleece. For an aurora night, top to toe:

Don't want to buy all this? Some aurora tours wait indoors, like the glass house on Cleary Summit, or in heated yurts, like Chena's tour up Charlie Dome, so you can step out when the sky lights up and back in to warm up. Chena Hot Springs lends parkas for its ice museum. Ask your tour operator what outerwear they provide before you pack.

A warm way to watch

Aurora Glass House Experience at Cleary Summit

You wait inside a glass house on Cleary Summit instead of standing in the snow. A good choice for a January trip, or for anyone who feels the cold.
