Tromsø's cold is manageable. The dark, the wet and the ice are the problem. Winter temperatures hover around freezing, so snow turns to slush and then to sheet ice, and you spend long nights standing still outside waiting for the northern lights.

Season by season
Winter
December–FebruaryDark, snowy and slippery. Highs are -1°C (30°F) in December, 0°C (32°F) in January and 1°C (34°F) in February, with lows of -5°C (23°F) and -3°C (27°F). January averages 17 rain days, mostly snow. The sun does not rise for several weeks around December, so you get a few hours of blue twilight. Pack a full layering system: thermal base layer, fleece or wool mid layer and a waterproof shell, plus insulated boots and ice cleats.
Spring
March–MayStill winter until April. March averages a 0°C (32°F) high and -5°C (23°F) low, April 3°C (37°F) and -2°C (28°F), and May warms to 9°C (48°F) with 14 rain days. Days lengthen fast and the snow reflects a lot of light, so bring sunglasses with your winter layers. Northern lights season ends around late March.
Summer
June–AugustCool, bright and changeable. Highs are 14°C (57°F) in June, 18°C (64°F) in July and 17°C (63°F) in August, with lows of 8–11°C (46–52°F). July is driest at 5 rain days, but August jumps to 11. The midnight sun means no darkness, so pack a sleep mask, a rain jacket and a warm layer for boat trips and hikes.
Autumn
September–NovemberThe wettest stretch. October averages 18 rain days with a 6°C (43°F) high and 2°C (36°F) low, and November drops to 2°C (36°F) and -3°C (27°F). September is the start of aurora season, with 13°C (55°F) highs. Pack waterproof boots and a shell; the first ice usually appears by November.

What shoes should you pack for Tromsø?
Insulated, waterproof winter boots with a deep tread, plus slip-on ice cleats or microspikes. Tromsø's streets freeze, thaw and refreeze, and the hills in the center turn into ice rinks. In summer, waterproof hiking shoes are enough for Fjellheisen and the island trails.
What do people wear in Tromsø?
Practical outdoor clothing, everywhere. Locals wear down parkas, wool layers and boots to work, to restaurants and to the cathedral concerts. Nobody dresses up. Indoors is warm, so wear layers you can take off.
What should you wear to see the northern lights in Tromsø?
Wear more than you think: you will stand still outside for hours at night, often inland where it is colder than town. Use a thermal base layer, a thick mid layer, an insulated jacket, insulated pants, wool socks, a hat, mittens and hand warmers. Many tour operators lend thermal suits; check before you go. Aurora season runs roughly September–March.
What plugs does Tromsø use?
Norway uses Type C and F sockets at 230V, the same as most of mainland Europe. US, UK and Australian visitors need an adapter. Phone and laptop chargers are fine at 230V.
