September at a glance
September opens the season. The nights are still short in the far north, but the weeks around the autumn equinox are among the most active of the year, and in Yellowknife and Fairbanks the lakes have not yet frozen, so a display can be reflected in open water. Reykjavik gets about 7.3 hours of darkness a night in September and Tromsø about 5.6.

Is a tour worth it in September?
The forecast is free, and on a clear night you can see the lights from the edge of most towns on this site. What a tour adds in September is the drive to the clear patch, a guide who reads tonight’s cloud and the aurora forecast, warmth for hours outside and photos of you; many also give a free retry or a refund if the night is blank. Book early in your stay so a second chance still fits.
