Short answer
- Pick Tromsø for fjords, whales in early winter, milder cold and a small city on the sea.
- Pick Rovaniemi for colder, drier nights, cheaper and shorter aurora tours, and snowmobiles, reindeer and Santa Claus Village.
- Either way: give yourself at least three nights. The aurora depends on the cloud more than on the town.
Both towns sit inside the band where the northern lights are most often overhead, so neither has a better aurora as such. What differs is the weather you look through, the length of the night, and what you do in daylight.

The weather you look through
Tromsø’s coastal climate keeps it milder, but it is cloudier. Tours compensate by driving: a chase to the islands or towards Finland is normal, and longer tours are the price of that. Rovaniemi’s inland climate is colder and often drier. Tours are shorter, and the best small groups still cross into Sweden or Norway when they need to.
The length of the night
In Tromsø the sun does not rise at all from late November to mid January. That means more dark hours for the aurora, and a few hours of blue twilight around noon. Rovaniemi, right on the Arctic Circle, never quite loses the sun: it peeks over the horizon for about two hours at midwinter. For the aurora this makes little difference, since both are dark from mid-afternoon.
What you do in daylight
This is usually the deciding factor. Tromsø is a city on the water: fjord cruises and, from about November to January, whale watching when orcas and humpbacks follow the herring. Rovaniemi is the base for classic Lapland: we list 157 snowmobile tours in Finnish Lapland against a handful in Tromsø, and far more husky and reindeer trips at lower prices. Read snowmobile tours in Lapland and husky sledding: Tromsø or Lapland.
What about Swedish Lapland?
Kiruna and Abisko, in Swedish Lapland, are a quieter third option. Abisko has a reputation for clearer skies than the surrounding area, and Kiruna has a small number of well-reviewed aurora tours, about €170 for a shared one. The choice is much smaller than in Tromsø or Rovaniemi.
The town matters less than the number of nights. Three gives you a real chance; one is a gamble anywhere.
