Worth Going Out

Northern lights in Tromsø in February

Norway. Figures for February 2027, calculated by us. Times are local.

Go

Yes: long, dark nights. In mid-February the sky is dark enough for the aurora from about 18:00 to 05:53, 11.8 hours a night.

Darkness through the month

1 February: 13.3 hours of darkness.
15 February: 11.8 hours.
End of February: 10 hours. The nights are getting shorter through the month.

“Dark” here means the Sun is more than 12° below the horizon. Faint aurora needs a darker sky; a strong display can show earlier in the evening.

The Moon in February 2027

New Moon: 6 February 2027. The week around it has the darkest skies.
Full Moon: 20 February 2027. A bright Moon makes the aurora look fainter, though it is still there.

What to expect

The aurora appears only on active nights, and only where it is clear. Plan several nights and check the forecast each day: how to read it.
On the coast the weather changes quickly. Tours often drive inland to look for gaps in the cloud, so a guided night can help even if you have a car.
