Northern lights forecast for Rovaniemi, Lapland
Rovaniemi sits just below the Arctic Circle, within reach of the auroral oval. On a dark, clear night the aurora borealis is common here. The hard part is knowing which night, and which hours.
What the forecast weighs
The forecast answers that question hour by hour. It brings together the three things that decide whether you will see anything:
- Aurora activity: how strongly the aurora is likely to reach this far south.
- Cloud cover: whether the light can get through to the ground.
- Darkness: whether the sun is far enough below the horizon.
The result is one viewing chance for each hour of the night, plus the best window to be outside. The data refreshes every hour through the season, from late August to early April.
