Anchorage in December: Snow, Dog Sledding, Northern Lights and Short Days

In December, Anchorage wakes up in the dark and the snow squeaks underfoot on the way to the coffee shop. Strings of white lights hang over the downtown streets, sled dogs bark at the start of a trail, and the Chugach Mountains turn pink for a little while when the low sun finally touches them. It is a month for a town under snow, with winter outings, long evenings and a real chance at the northern lights.

What is the weather like in Anchorage in December?

December in Anchorage is cold, snowy and dark for most of the day, though the air is mostly dry and the snow comes in modest, steady doses rather than long storms.

Month	Average high (°F)	Average low (°F)	Precipitation (in)	Days with precipitation	Daylight on the 15th
November	28.9	18.3	1.19	3.7	7 h 22 min
December	25.0	13.8	1.16	4.0	5 h 34 min
January	22.7	11.0	0.75	2.7	6 h 20 min

Afternoons stay below freezing, so whatever falls from the sky falls as snow, and the roads and trails keep their white coat all month. Snowfall in an average December reaches about 18 inches at the airport, a clear step up from November. Mornings are the coldest part of the day, and the sun is slow to show itself.

Precipitation arrives on only a handful of days, so most days are dry, often with a hard, bright cold. The light is the real character of the month. Daylight is brief, the sun hangs low along the horizon, and the glow of dawn and dusk can seem to blend into one long, soft stretch around midday. Plan outdoor time in the middle of the day and leave the evening for something warm.

For you, they mean insulated boots, a real winter coat and layers you can add or shed when you step into a heated café. Wind can make a cold afternoon feel colder, and wet feet are what end a walk early.

What to do in Anchorage in December

December in Anchorage is built around the dark and the snow, and the town treats both as an invitation. Dog sledding is in season, the northern lights are active in the skies over the city, and the streets take on a holiday glow that builds toward Christmas Day on December 25. Everything you do is shaped by the short daylight, so the best plan is to put your active hours in the middle of the day and keep your evenings for lights, food and sky.

Downtown is the easiest place to feel the mood. Shop windows and trees are strung with lights, people walk fast with scarves pulled up, and warm doorways smell of coffee and baking. Reindeer sausage, salmon chowder and a hot chocolate or a strong coffee are the kind of food that suits a walk in this cold.

Dog sledding

Dog sledding in Anchorage typically runs from October through March, so December sits in the heart of the season. Alaska sled dogs traditionally pull side by side in pairs rather than fanned out in front, and the sleds are the built-up type with a high rail on each side. Seeing a team leap and yelp at the start line, then fall into a silent, steady trot once the sled moves, is one of the most memorable moments of the month.

The cold and snow are the point here, so dress for standing still as well as for moving. Whether you ride or only watch, you will leave with a feel for the working relationship between musher and dogs that is central to Alaskan winter life. The Iditarod Trail Sled Dog Race is an iconic winter event in Alaska, and the same culture runs through every kennel in the area.

Northern lights from the city

From late September through the middle of April, the northern lights are active in the skies over Anchorage. December has the longest nights of the season, which gives the sky plenty of time to perform if it wants to. Clear weather is what counts. Clouds can hide even a strong display, and the lights are a chance, never a promise.

Auroral activity tends to be stronger around the spring and fall equinoxes than around midwinter, so December is not the statistical peak, but the dark hours more than make up for it. Anchorage is considered one of the best bases for chasing the aurora, with many good viewing places reachable from the city. For travelers set on a longer search, Fairbanks has an aurora season running from August 21 to April 21, and a stay of at least three nights in clear weather makes a sighting highly likely.

Alaska Wildlife Conservation Center

The Alaska Wildlife Conservation Center is a sanctuary dedicated to conservation, education, research and quality animal care. It takes in injured and orphaned animals year-round, and most of the animals that arrive become permanent residents with a lasting home. That gives the visit a different feel from a zoo, because every animal has a story.

In December, the animals live in spacious enclosures and the snow gives the whole scene a northern look that is hard to find in summer.

When the weather turns raw, the museums and cafés of downtown fill the gap. A slow lunch, a pot of tea and a window view of snow falling past the streetlights is a perfectly good way to spend a December afternoon in Anchorage.

A two-day itinerary for Anchorage in December

Day 1. Start late, because the sun does. Take a long breakfast at a downtown café while the sky lightens, then walk the streets once the day is as bright as it will get, with the lights, the snowbanks and the mountains in view.

By the time the afternoon fades, head back toward town and settle into a restaurant for a warm meal such as salmon chowder or something with reindeer sausage. If the sky is clear after dinner, go out and look for the northern lights, wrapped up well and ready to stand a while in the cold. If clouds roll in, a bar with live music or a cozy hotel lounge does just as well.

Day 2. Make the sled dogs your morning and midday plan, since dog sledding in Anchorage typically runs from October through March and the daylight is best for it. Dress for the cold of the ride itself, which is colder than the walk to the car. Afterward, warm up with a long lunch at a local diner or café.

Spend the afternoon indoors if the weather has turned, at a museum downtown or in shops looking for Alaska crafts and holiday gifts. As darkness settles, head to a quiet spot away from the brightest streetlights for another try at the aurora, then finish with a hot drink and a last look at the lights strung over the city.

Is Anchorage busy in December?

Anchorage in December is a winter town, and the pace is that of a place going about its own holiday season rather than hosting a rush of visitors.

The season that fills the days is winter itself. Dog sledding is active, the aurora season runs until the middle of April, and Denali National Park is in its winter season, from late September until early May, with the Murie Science and Learning Center at mile 1.3 on the Denali Park Road serving as the winter visitor center. For anyone coming for snow and dark skies, that means the main attractions are in operation.

The mood in town is local. People gather for the holidays, concerts and community events, and Anchorage has a variety of festivals, live music and cultural celebrations through the year. The streets feel quiet and unhurried, and the short days encourage an early evening and a slow, cozy rhythm.

What to pack for Anchorage in December

Pack for standing outside in the cold and for stepping into heated rooms, with each piece chosen to keep you outdoors longer.

Insulated, waterproof winter boots with good traction, because snow and ice cover the ground all month.
A warm winter coat and thermal base layers, since afternoons stay below freezing.
A hat, gloves or mittens and a scarf, for sled rides and aurora watching.
Warm socks, plus a spare pair, because wet feet end an outing fast.
A small camera or phone with a battery you can keep warm, for the lights and the snow.
Sunglasses, since low winter sun on snow can be bright.

Good to know before you go

What matters most in December is the daylight, which is brief, so plan the active part of each day around the middle hours. Christmas Day, December 25, is a holiday, and the days around it will feel quieter and more local.

Ted Stevens Anchorage International Airport is 5 miles southwest of downtown, and it is a hub for Alaska Airlines. Winter weather can shape travel plans, so allow room in your schedule on arrival and departure days.

Anchorage in December vs November and January

Moving the trip earlier to November gives you a little more daylight and less snow, with the cold a notch softer. The days are still short, and the town is not yet fully in its winter dress, but the aurora season is already running and dog sledding is in season, so the main winter activities are there.

Moving the trip later to January brings colder air, but also less precipitation and a clear return of the light, since the days begin to lengthen. The holiday lights are still up in the early part of the month, though the Christmas mood fades. Aurora and dog sledding remain in season, so you lose little in activities and gain a bit more daylight.

If you want the holiday atmosphere, the lights and the longest nights, stay with December. If you would rather have a bit more light for outings, November or January suits you better. For winter travelers who care mainly about the aurora and sled dogs, any of the three months works.

Is December a good time to visit Anchorage?

Yes, for travelers who want winter on its own terms: snow underfoot, dark skies for the aurora, sled dogs on the trail and a town glowing with holiday lights.

Those who love cold-weather outings and cozy evenings will be happy, as will anyone who hopes for the northern lights, which are never guaranteed but have long nights to work with. Travelers who need long daylight hours for sightseeing or dislike cold and ice should choose another month.

On arrival, dress warmly and give yourself a slow first day, with a walk downtown in the best light and a hot meal. Then plan the sled dogs for a day with a clear sky and keep an evening free for the aurora.

What stays with you from Anchorage in December is the quiet. Snow muffles the streets, the lights shine against the early dark, and a sky that sometimes glows green hangs over a city at the foot of the Chugach Mountains.
