Alta · December and January

Alta in December and January: blue twilight days, dry cold and the igloo hotel opening.

From about 26 November to 16 January the sun stays below the horizon in Alta, but civil twilight gives four to five hours of blue light around midday and the snow doubles it. The air is dry and cold, with average lows of −8 °C in December and −10 °C in January, the igloo hotel opens on about 20 December, and the herring can bring whales into the fjord.

What a polar-night day in Alta looks like

The sky starts to lighten around 08:30, turns deep blue and then pink over the mountains across the fjord at midday, and fades to dark by about 14:30. The cathedral's titanium skin and the snow reflect what light there is, so the centre feels bright rather than gloomy at lunchtime. Photographers get two hours of blue-hour light without a sunrise.

The cold is dry. A day at −8 °C in Alta feels easier than −1 °C with sleet on the coast, provided the wind stays down; the plateau and the fjord shore are windier than the town. Pavements are packed snow rather than slush, so grip soles or spikes matter more than waterproof shoes.

The igloo hotel, whales and the aurora in one week

Sorrisniva rebuilds its igloo hotel from snow and ice on the riverbank every year and opens it around 20 December, so a December trip before that date cannot include the night. One night in the igloo with a warm lodge night beside it is the common pattern, and the sauna and breakfast are in the heated building.

In recent winters herring have drawn humpbacks and orcas into the Altafjord from about November into January, and one or two heated boats sail from the town. The season moves with the fish and can end early, so if the whales are the reason for the trip, confirm the last published departure date before booking flights. Put the guided aurora evening on a different night from the whale day; both are long and cold.

  • Igloo night: book first; a few dozen rooms and a short season.
  • Whale boat: confirm dates each year; sightings are frequent in season but never certain.
  • Aurora evening: night two, with night three kept free for a retry.
Where to stay

Where to stay in Alta in December and January

Polar-night evenings are tours and dinners, so a central hotel with breakfast and a pool saves the most time; the valley suits the igloo night and a kennel stay.

Christmas and New Year: worth it or avoid?

Between 23 December and 2 January hotel rates are the highest of the winter, the shops and many restaurants close on 24 and 25 December, and some operators pause. Alta does not stage a big city celebration; the appeal is the quiet, the cathedral services and the snow. If the festive dates are not essential, the first three weeks of December give the same darkness with easier bookings, and the second half of January adds the returning sun at lower prices.

What to book and in which order

Fix the dates around the igloo opening and the whale season if either matters. Book flights that land by early afternoon, then the base, then the guided aurora evening for night two, then a husky or snowmobile morning on a middle day. Reindeer visits, the snowshoe walk and the museum fit around the rest and rarely sell out.

Packing for dry cold

Pack wool base layers, an insulated jacket, windproof trousers, insulated boots with grip and mittens over thin gloves. Operators lend thermal suits for sled, snowmobile and boat trips, so the town outfit needs to handle −10 °C and a walk, not the plateau. Sunglasses help for the bright twilight on snow, and hand warmers are cheap insurance on the aurora stops.

Practical questions

Questions travelers ask before booking

Answers use the sources listed below. Re-check live hours, weather and operator terms close to the travel date.

Is it dark all day in Alta in December?

No. The sun does not rise, but civil twilight gives four to five hours of blue light around midday and the snow reflects it. It is dark before 15:00, and the town runs on street light after that.

Is December or January better for northern lights in Alta?

Both have long dark hours and dry weather. January is colder and often clearer, and after about 16 January a brief sunrise returns; prices are lower after New Year. December has the busier Christmas weeks and the igloo opening on about 20 December.

Do tours run on Christmas Eve and Christmas Day?

Some do and some pause; the listing shows available dates. Shops and most restaurants close early on 24 December, so book dinner or choose a lodge with an included meal.

How cold is Alta in January compared with Tromsø?

Colder but drier: an average low of about −10 °C in Alta against about −5 °C in Tromsø, with roughly a third of the precipitation. Dry cold at −10 °C with the right layers is easier than sleet at −1 °C.
