Christmas in Alaska? It’s cold—deep cold, honestly—and the days just don’t last long. Snow is everywhere.
If you’re in Southcentral Alaska, expect daytime temperatures near 20°F during the holidays. Interior and Arctic areas? They often drop way below zero.
Snow falls across the state, so a white Christmas is basically guaranteed no matter where you land.
What’s wild is how much the weather shifts depending on where you are. Anchorage feels cold but doable, while Fairbanks and the Arctic? Those can be brutal.
Coastal towns get more clouds and precipitation, and inland spots swap that out for serious cold.
The weather shapes everything—your plans, your activities, even your mood.
From dog sledding under the northern lights to just hanging out in a snowy town, it’s a vibe you won’t find anywhere else.
If you know what’s coming with temperatures, daylight, and snow, you can plan for both the tough parts and the magic of an Alaskan Christmas.
Overview of Alaska’s December Climate
In December, you’ll deal with short days, freezing temperatures, and lots of snow in most of Alaska.
The conditions change a lot, from the milder southeast coast to the bitter interior and Arctic.
Key Features of Alaska Weather in December
December kicks off the coldest stretch of the year in Alaska.
Snow covers most of the state, but coastal areas get wetter, heavier snow, while the interior stays dry and powdery.
Storms roll in fast along the Gulf of Alaska, bringing strong winds and heavy precipitation.
Inland, it’s much calmer, but the cold really bites.
Humidity drops in the interior, so the cold feels even sharper.
Coastal places like Anchorage and Juneau? They feel damp and icy most days.
You’ll probably run into icy roads and poor visibility when snow and fog team up.
Travel plans can get disrupted, so it’s best to stay flexible when you’re moving around Alaska in December.
Temperature Ranges Across the State
December temperatures swing wildly depending on where you are.
Fairbanks and the interior usually get the worst of it, with highs around -5°F to 5°F (-21°C to -15°C) and lows that can sink below -20°F (-29°C).
Anchorage stays a bit warmer, with highs near 25°F (-4°C) and lows around 14°F (-10°C).
Southeast coastal towns like Juneau and Ketchikan keep warmer thanks to the ocean, with highs in the 30s to low 40s°F (0–6°C).
Up north, Arctic spots like Utqiaġvik (Barrow) average highs near -5°F (-21°C) and lows at -15°F (-26°C).
Wind chills up there? They’re no joke.
| Location | Avg High (°F) | Avg Low (°F) |
|---|---|---|
| Anchorage | 25 | 14 |
| Fairbanks | 1 | -17 |
| Juneau | 33 | 24 |
| Ketchikan | 42 | 33 |
| Nome | 13 | 3 |
| Utqiaġvik | -5 | -15 |
Daylight Hours and Winter Solstice
December daylight is in short supply, especially near the winter solstice.
Anchorage gets about 5 to 6 hours of daylight, with sunrise close to 10:00 AM and sunset by 3:30 PM.
Fairbanks? Even less.
You’ll see just 3 to 4 hours of dim daylight in late December, with sunrise near 11:00 AM and sunset by mid-afternoon.
That leaves you in long stretches of twilight and darkness.
In Arctic communities like Utqiaġvik, the sun doesn’t rise at all for weeks.
This polar night hangs around until mid-January.
Southern coastal cities—think Juneau and Ketchikan—do a bit better, with about 6 to 7 hours of daylight around Christmas.
These daylight patterns really shape how you live and travel, so you’ll want to plan around the available light in December.
Typical Temperatures Around Christmas
December in Alaska? It means short days, long nights, and freezing conditions almost everywhere.
Coastal areas stay a little milder, but the interior can get downright frigid.
If you know these differences, you’ll be much better prepared for a safe, comfortable trip.
Temperature Patterns in Anchorage
Anchorage usually sits at daytime highs between 20°F and 25°F and nighttime lows near 10°F in late December.
Snow’s a regular thing, and the city averages about a foot of it for the month.
You’ll get around 5 to 6 hours of daylight near Christmas, so outdoor plans need to fit in a short window.
Anchorage feels easier to handle than the interior, thanks to those “warmer” temps.
Cold snaps can drag temps lower, but it’s rare to see readings below 0°F here compared to up north.
If you’re heading outside, don’t forget insulated boots and plenty of layers.
Temperature Patterns in Fairbanks
Fairbanks? It’s one of the coldest spots in Alaska during December.
Around Christmas, average highs hover near 0°F and lows often drop to -15°F or lower.
Long cold waves can push things below -30°F.
Daylight is almost nonexistent, with less than four hours of sun each day.
Combine that with the cold, and you’ve got a much tougher environment than the coast.
Snowfall’s lighter than Anchorage, since Fairbanks sits in a drier interior climate.
Still, the deep cold keeps snow locked in place all winter.
If you’re traveling here, prepare for extreme cold exposure and barely any daylight.
Temperature Patterns in Juneau
Juneau, down in the Inside Passage, has a much gentler December.
Around Christmas, daytime highs hit 34°F to 36°F and lows stick near 25°F.
It might snow, but rain is just as likely, thanks to the coastal location.
Daylight’s still short, with about six hours of sun a day.
The constant clouds and wet weather can make it feel colder than you’d think.
Most travelers find Juneau’s winter easier than the interior.
You’ll want waterproof outerwear as much as warm layers, because wet snow and rain are a given.
Snowfall and Precipitation During the Holidays
December brings steady snowfall, some rain along the coast, and snow cover almost everywhere.
Conditions change a lot, from the soggy coasts to the dry interior.
Average Snowfall Amounts by Region
Snow totals swing a lot across Alaska.
Anchorage usually gets about 16 inches of snow in December.
Fairbanks, up north, averages 10 to 12 inches, but the snow sticks around longer thanks to the deep freeze.
Coastal cities can see heavier snow.
Kodiak gets close to 9 inches, while Homer only sees about 3 inches.
In Southeast Alaska, snow mixes with rain, but places like Juneau and Sitka still get about 6 to 8 inches.
Ketchikan is one of the wettest towns, pulling in over 16 inches of precipitation—most of it as snow.
Smaller spots vary too.
Bethel in Southwest Alaska averages just over 1 inch.
Unalaska in the Aleutians often gets less snow but deals with wet, messy weather from the ocean.
Rainfall and Mixed Precipitation
Not all December precipitation comes down as snow.
Coastal regions like Ketchikan, Sitka, and Juneau often see a mix of rain and snow because of the milder ocean air.
Take Ketchikan—it averages 16 inches of precipitation, and a lot of that is rain.
In Homer and Kodiak, rain can show up during the holidays, especially when temps flirt with freezing.
Unalaska in the Aleutians gets frequent rain and wet snow, not much deep snowpack.
By contrast, interior cities like Fairbanks and Tok almost never see rain in December.
It’s just too cold, so all the precipitation falls as dry, powdery snow.
That difference really shows how Alaska’s size and geography play into holiday weather.
Snow Cover and Christmas Scenery
Snow cover? It’s almost a sure thing across Alaska in late December.
In Fairbanks and the Interior, snowpack runs deep and steady, so the winter landscape stays intact.
Anchorage usually has a blanket of snow by Christmas, though sometimes there’s a brief thaw.
Southeast towns like Juneau and Sitka might have patchy snow thanks to rain, but higher ground holds it well.
Kodiak and Homer often get fresh snow that brightens things up, even if rain occasionally wipes some away.
Even in the rainier spots, you’ll see at least a little snow on the ground for the holidays.
Traveling through Alaska in December is visually stunning, whether you’re deep in the frozen Interior or along the stormy coast.
Regional Weather Differences Across Alaska
Christmas weather in Alaska depends a lot on where you go.
Coastal towns stay milder but get wetter, while inland and northern areas turn extreme with cold and barely any daylight.
You might see heavy rain near the Pacific or deep snow and subzero temps in the Arctic.
Weather in Southeast Alaska: Sitka, Ketchikan, Juneau
Southeast Alaska’s maritime climate keeps winters milder than the rest of the state.
In December, you’ll see daytime highs near 35–40°F and lows close to freezing.
Snow falls, but rain and overcast skies are more common.
Juneau, Ketchikan, and Sitka usually get 10–20 days of precipitation in December.
Rain shows up more than snow, especially in Ketchikan, which is honestly one of the wettest cities in America.
Daylight sticks to about 6–7 hours, so plan your outings accordingly.
If you’re not a fan of harsh cold, this region gives you the most moderate temps, though you’ll want waterproof gear.
Pacific winds can make things feel colder, even if the thermometer says it’s above freezing.
Weather in Southcentral and Southwestern Alaska: Anchorage, Kodiak, Homer
Southcentral and Southwestern Alaska bring colder but still unpredictable weather.
Anchorage averages highs around 20–25°F and lows near 10°F in December.
Snow’s common, and the city usually keeps a solid snowpack through the holidays.
Kodiak and Homer, both on the coast, run a bit warmer.
Highs reach the mid-30s, and lows stay close to freezing.
These spots also get lots of clouds and rain mixed with snow.
Coastal storms sometimes whip up strong winds, especially near Kodiak Island.
Daylight here runs from 5–6 hours in Anchorage to a bit more on the coast.
If you’re driving, watch out for icy roads and poor visibility.
Snow and coastal weather make this area less predictable than the Interior, but it’s not as severe as the Arctic.
Weather in Interior and Western Alaska: Fairbanks, Bethel, Unalaska
Interior Alaska—think Fairbanks—has some of the coldest holiday weather you’ll find.
Average December highs reach only 0–5°F, with lows often dropping to -15 to -20°F.
Snow is steady, but skies can be clearer than on the coast, so you might catch the northern lights.
Western Alaska, like Bethel, gets hit by the Bering Sea.
Temps here are a little warmer than Fairbanks, with highs in the teens and lows near single digits.
Snow and wind show up often, and storms can mess with travel plans.
Farther out in Unalaska, the Aleutians bring their own pattern.
Winters are windy, wet, and cloudy, with highs in the mid-30s and lows near freezing.
Snow mixes with rain, and gales off the North Pacific are pretty common.
If you’re visiting, get ready for weather that changes on a dime.
Weather in Arctic Alaska: Barrow and Northern Communities
Arctic Alaska, especially Barrow (Utqiaġvik), really pushes the limits during Christmas. Temperatures usually hang below -10°F, and sometimes they dive to -20°F or colder. Strong winds whip through, making wind chills downright dangerous.
Snow falls pretty often, but honestly, the real challenge is the darkness. Barrow goes through a full-on polar night in December, so the sun never peeks above the horizon. You might catch a few hours of twilight, but that’s about it.
If you’re headed to these northern communities, you need to brace for whiteout conditions, blowing snow, and poor visibility. Storms can shut down roads and ground flights. Anyone chasing extreme cold and those rare polar vibes will absolutely find them here.
Winter Activities and Holiday Atmosphere
Alaska’s cold doesn’t stop the fun. If anything, it kind of unlocks a whole new set of winter sports, festive events, and wild scenery that you just don’t get any other time of year.
Outdoor Recreation: Skating, Skiing, and More
There’s a ton to do outside, all across Alaska. In Anchorage and Fairbanks, ice skating rinks—both natural and the ones the city keeps up—pop up everywhere. People gather on frozen lakes, and city rinks stay busy and well-lit, even when it’s dark.
Skiing is a big deal, too. Cross-country trails wind through woods near Fairbanks and Anchorage, offering quiet, snowy escapes. Alyeska Resort draws downhill skiers with its groomed runs and solid snow cover.
Snowmobiling, dog mushing, and snowshoeing keep things lively. In Homer, you can hit coastal trails for snowy adventures with ocean views. Rental shops and guided tours make it easy to jump in, even if you’re new to it all.
Holiday Events and Local Traditions
December really brings out the holiday spirit in Alaska’s towns. In Fairbanks, the Christmas in Ice event shows off glowing ice sculptures. Families wander the displays, play winter games, and soak up the lights.
Anchorage goes all out with tree-lighting ceremonies, holiday markets, and parades. Streets get decked out, and everyone seems to come together for these gatherings. Even smaller towns like Homer host craft fairs and concerts, giving you a chance to meet locals and pick up handmade gifts.
Long nights mean holiday lights look even more magical. Neighborhoods and downtown areas go all in with bright decorations, so you’ll find a festive vibe almost everywhere.
Wildlife and Scenic Winter Landscapes
Alaska’s winter scenery is simple but stunning. Snow covers forests, rivers, and mountains, opening up wide, quiet views. Around Anchorage, snowy mountain ranges seem to glow, even when daylight’s in short supply.
Wildlife doesn’t take the winter off. Moose wander near Fairbanks and Anchorage, sometimes right along the roads or trails. You’ll spot eagles in coastal areas like Homer, where open water draws them in.
On clear nights, the Interior’s skies give you a real shot at seeing the northern lights. If clouds stay away, you might catch green and purple ribbons stretching across the sky—honestly, it’s unforgettable.
Travel Tips for Visiting Alaska at Christmas
Visiting Alaska in December means you’ll need to prep for freezing temps, short days, and snowy or icy roads. What you pack and how you plan your days can make a big difference.
Packing and Clothing Recommendations
You’ll face subzero temperatures up north and in the Interior, while the coast can be a bit milder but wetter. Layers are your best friend. Go with a base layer (thermal underwear), an insulating layer (fleece or wool), and a tough outer shell (something waterproof and windproof).
Don’t forget insulated boots with good grip. Regular shoes won’t cut it on ice or in deep snow. Thick wool socks, waterproof gloves, and a warm hat that covers your ears are all must-haves.
For extra comfort, toss in hand warmers, a scarf or neck gaiter, and lined pants. Sunglasses help, too—snow glare can be brutal, even with a low sun. If you’re going out to watch the northern lights, wear more layers than you think you’ll need, because standing outside at night gets cold fast.
Planning Around Short Daylight Hours
Daylight is in short supply in December. Fairbanks gets maybe 4 hours, Anchorage a little closer to 5, and up in the Arctic, you won’t see the sun at all.
Plan your outdoor activities for midday. Dog sledding or skiing works best when there’s some light. Save museums, shopping, or local events for the long dark hours.
If you’re walking after sunset, bring a headlamp or small flashlight. Some streets and trails can get icy, and lighting isn’t always great, especially in smaller places. Planning meals and travel around what daylight you have can make things run smoother and keep you safer on the road.
Safety Considerations in Winter Weather
Driving in Alaska in December? You’ll want to be extra cautious. Icy, snow-packed roads and dim lighting can make things tricky.
If you rent a car, check that it has winter tires, an emergency kit, and a full tank of gas. I always toss in extra blankets, some food, and water—just in case you get delayed somewhere.
Always check the weather forecast before you head out. In the Interior and Arctic, sudden cold snaps sometimes drop temps way below -20°F.
Along the coast, watch out for heavy snow or freezing rain. That stuff can sneak up on you.
When you’re outside, try to keep your skin covered so you don’t get frostbite.
If you’re hiking or snowmobiling, bring a buddy and tell someone your plans. Cell service drops out in lots of remote spots, so I’d carry a map or an offline GPS device.
