Traveller notes on Tromsø in December
Other months in Tromsø
Tromsø's forum calls October the wettest month of the year locally — genuinely no pattern to the rain, capable of days on end wet or days on end cloudy, changing quickly with sudden clear breaks. Regulars flag it as touch-and-go for early winter conditions too: some years bring icy roads and snow on the ground by late October, others stay closer to freezing rain. Layered, genuinely waterproof and windproof gear is standard advice regardless.

1 Nov – 20 Jan · usuallyWhale seasonThe herring come into the fjords north-east of the city and the whales follow them, in the four hours of blue twilight that count as day. Boats run from Skjervoy rather than Tromso itself.
