Aurora borealis forecasts in Norway
There is no single aurora borealis forecast for Norway, and any number offered as one would be wrong almost everywhere in it. The auroral oval reaches part of the country on a quiet night and the rest of it only during a storm: Kristiansund needs Kp 3, while Kristiansand needs Kp 5 — a storm level that arrives a fraction as often.
So this page is a directory rather than a forecast. Each of the 37 places below has its own page with tonight’s hourly odds, the next 30 nights, and the drive to darker sky that matters more than the forecast does.
Where the aurora borealis is visible on the most nights in Norway
Counting only nights when the storm was strong enough for that location and the sky there was dark enough at the same time. That is why the far north of Norway does not automatically top the list: the closer a place is to the pole, the more of its summer never gets dark at all.
| Place | Kp needed | Nights / year |
|---|---|---|
| Kristiansund | Kp 3 | 116.0 |
| Trondheim | Kp 3 | 115.6 |
| Levanger | Kp 3 | 114.3 |
| Mo i Rana | Kp 3 | 105.7 |
| Bodø | Kp 3 | 103.5 |
| Harstad | Kp 3 | 99.5 |
| Tromsø | Kp 3 | 97.8 |
| Alta | Kp 3 | 96.4 |

What the Kp number means
Kp grades the strength of a geomagnetic storm from 0 to 9. The higher it runs, the further from the pole the auroral oval spreads, so every place has a Kp at which the aurora borealis first reaches it — that is the number beside each link above. In Norway those thresholds run from Kp 3 to Kp 5. A place at Kp 3 is inside the oval on an ordinary quiet night; one at Kp 5 needs a strong storm, which is a few nights a year rather than a few a month.

Common questions about the aurora borealis in Norway
Can you see the aurora borealis in Norway?
Yes, in all 37 places in Norway with a forecast page: each averages at least one viable night a year, and Kristiansund leads them at 116.0 nights.
Where in Norway is the aurora borealis seen most often?
Kristiansund. It needs Kp 3 and averages 116.0 viable nights a year, more than anywhere else in Norway we publish a forecast for. Further north is not automatically better: the closer a place is to the pole, the more of its summer never gets dark at all.
What Kp index do you need to see the aurora borealis in Norway?
Between Kp 3 and Kp 5, depending where you stand. Kristiansund needs Kp 3; Kristiansand needs Kp 5, and storms that size are a small fraction as frequent.
Is there one aurora borealis forecast for the whole of Norway?
No. The auroral oval reaches some parts of Norway on a quiet night and others only in a severe storm, so a countrywide number would mislead more than it told you. The forecast is published per place, so open the page for where you will actually be.
