December: Christmas magic and polar night
December is the season of kaamos, when the sun barely rises. It is not pitch black: for a few hours, a deep blue and pink twilight lies over the snow. With Christmas lights everywhere and Santa Claus Village in full swing, it is the most atmospheric time — and the busiest and most expensive. Book early. See Santa Claus Village.
January to March: the real Arctic winter
After the holidays, crowds and prices drop and temperatures often fall further — January is usually the coldest month. From February, light returns quickly. Late February to March is a favourite of many Lapland lovers: lots of snow, sunshine, long days for husky and snowmobile safaris and often clear nights for auroras. Watch out for school holiday weeks.
Winter experiences for your dates
Autumn: ruska and early auroras
From late August, nights grow dark enough for the northern lights, often reflected in still lakes. In September the forests turn red and gold (ruska). No snow activities, but fewer visitors and lower prices.
Summer: the midnight sun
From early June to early July the sun does not set. Santa Claus Village is open, reindeer graze on summer pastures and canoeing and hiking replace sleds. Mosquitoes can be plentiful in July — bring repellent.

What to wear at −20 °C
- Layering: merino or synthetic base layer, fleece or wool mid-layer, windproof insulated outer layer.
- No cotton next to the skin — it holds moisture and chills you.
- Feet: insulated winter boots with room for two pairs of socks (thin + wool).
- Hands and head: mittens rather than gloves, a hat covering the ears, a neck gaiter or balaclava.
- Batteries: keep your phone in an inside pocket and bring a power bank.
Most tours lend thermal overalls, boots and mittens. Family tips in our itineraries.
