Sweden. Figures for December 2026, calculated by us. Times are local.
Go
Yes: long, dark nights. In mid-December the sky is dark enough for the aurora from about 15:47 to 07:32, 15.5 hours a night.
Darkness through the month
- 1 December: 15 hours of darkness.
- 15 December: 15.5 hours.
- End of December: 15.5 hours. The nights are about the same through the month.
- Around the middle of the month the Sun does not rise at all: this is the polar night. There are still some hours of twilight around midday.
“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 December 2026
- New Moon: 9 December 2026. The week around it has the darkest skies.
- Full Moon: 24 December 2026. 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.
- There is very little artificial light, and the national park is right next to the village.
