Greenland in December: Deep Polar Night, Dog Sleds on Sea Ice, and Arctic Christmas

December is Greenland at maximum darkness. In Ilulissat, the sun set in late November and won’t rise again until mid-January. In Nuuk, the sun rises for fewer than 3 hours and barely clears the horizon. The sea ice is thickening toward the January-February peak. The dog sled season is underway, with the first established routes operating across Disko Bay’s forming ice. And in Greenland’s settlements, the Christmas (Juullip) celebration has a particular intensity — the contrast of warmth, light, and community against the surrounding polar darkness makes the holiday more meaningful here than almost anywhere else.

Weather & Conditions

Ilulissat (Disko Bay): -12 to -22°C. Full polar night. Sea ice at 0.8–1.2m and thickening.

Nuuk: -5 to -13°C. Under 3 hours of twilight daily. Snowbound.

Sisimiut: -8 to -18°C. Dog sled season underway. Sea ice routes establishing.

Kangerlussuaq: -15 to -30°C. Extreme cold. Best aurora conditions in Greenland.

Sea ice: Thickening. Dog sled routes operational on established bays; long-distance routes building.

What to Do

Dog sledding — season building: The sea ice in December is thickening toward its February peak. Dog sled routes from Ilulissat and Sisimiut are operating, with short to medium-distance routes established by mid-December. Multi-day expeditions of the scale possible in February aren’t yet reliable, but day and overnight sled trips are running. The experience of a dog sled in polar night — traveling by headlamp across the ice, the silence broken only by the dogs — is unique to this time of year.

Northern Lights — prime viewing window: December’s polar darkness gives maximum aurora viewing hours. The Kp index drives aurora intensity; December has no competitive disadvantage over other winter months and significant advantage over any summer month. Clear nights at Kangerlussuaq are statistically more common than on the coast. On an active aurora night in December — with the lights filling the sky over sea ice and frozen icebergs — Greenland delivers one of the most extraordinary natural light shows available anywhere.

Arctic Christmas, Nuuk: Juullip (Christmas) in Greenland merges Nordic and Greenlandic traditions. The churches — particularly Nuuk’s cathedral — hold Christmas Eve services attended by the community in traditional Greenlandic national dress. The Christmas markets in Nuuk sell local crafts, dried fish, smoked meats, and traditional food. The darkness makes the lights more vivid: windows glowing through polar night, community gatherings in the warmth against the surrounding ice.

Polar night photography, Ilulissat: The December polar night — with icebergs in various states of freezing into the sea ice, the blue-purple midnight twilight visible for an hour or so at midday, and the Northern Lights overhead — creates photographic material that doesn’t exist at any other time or place. Long-exposure photography at -20°C requires specific preparation but produces extraordinary results.

Kangerlussuaq ice cap access: The Greenland Ice Cap edge, 25km from Kangerlussuaq, is accessible by snowmobile in December. The ice cap in midwinter — the vast white plateau stretching 2,500km to the east — is one of the genuinely extraordinary landscapes on earth.

Festivals & Events

Christmas (Juullip, December 24–26): The major community celebration in Greenland. Church services on Christmas Eve in Greenlandic and Danish. Traditional food — mattak (beluga whale skin), dried reindeer, and local seafood — served in community settings.

New Year (Nytår, December 31): Celebrated in Greenlandic communities with fireworks — extraordinary against the polar night sky.

Practical Tips

Extreme cold: December in Kangerlussuaq and Ilulissat can reach -30°C with wind. This is beyond the capability of standard winter gear. Expedition-rated gear (parka to -40°C, boots to -40°C, face protection) is required for extended outdoor time. Rental gear is available at the Hotel Kangerlussuaq and some Ilulissat operators.

Polar night and mental experience: 24-hour darkness is not for everyone. Some visitors find it oppressive; others find it beautiful. Go in knowing which you are — and if you’re uncertain, the first aurora on a clear night will answer the question.

Christmas travel in Greenland: Air Greenland operates during the Christmas period but with limited frequencies. Book early December and late December flights well ahead — the Christmas travel period sees Greenlandic residents returning home from Denmark.

Dog sled December availability: the season is building, not at peak. Confirm specific route availability with operators in November before booking December.

Who December Is For

Dog sledding enthusiasts who want the early season with polar night. Northern Lights hunters who want maximum darkness. Arctic Christmas cultural participants. Polar night experience seekers who want to understand what 24-hour darkness actually means and feels like. And extreme winter travelers for whom the combination of -20°C, no sun, and aurora overhead is precisely the point.
