Worth Going Out

Northern lights in Yellowknife in October

Canada. Figures for October 2026, calculated by us. Times are local.

Go

Yes: long, dark nights. In mid-October the sky is dark enough for the aurora from about 19:59 to 06:48, 10.8 hours a night.

Darkness through the month

1 October: 9.3 hours of darkness.
15 October: 10.8 hours.
End of October: 12.3 hours. The nights are getting longer 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 October 2026

New Moon: 10 October 2026. The week around it has the darkest skies.
Full Moon: 26 October 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.
Winter nights are very cold. Several operators run heated viewing cabins outside town.
