The sky here is dark enough for auroras from late August to early April, and the best odds are from September to March on clear nights. They need three things at once. It must be dark, the sky must be clear, and the sun must be active enough to send charged particles our way.
We cannot control any of them, which is why we suggest at least three nights. Over three nights most guests see them at least once, but December and January are cloudier, so the clear nights are fewer. In the midnight-sun months, from late May to late July, you will not see auroras at all.
Our village sits away from town lights, so it is a good place to wait, and if the sky opens we let you know. From September to March you can also wait for the lights by the fire, with smoked salmon on the embers.
