October is when the darkness comes back. At around −4°C the days collapse quickly, and from about 26 October the sun stops rising for the season — the polar night begins. Aurora season opens, the first winter trips start, and the last boats run early in the month. This is the start of our Polar Night season. The verdict: a strong transitional month for aurora with a little remaining twilight.
Early October still has real daylight and the tail of the boat season; by late October it is dark, snowy, and fully winter. It is a fast, dramatic handover.

The cold sets in and snow starts to build. The late-month edge of the polar night gives some travellers the best of both: long dark nights for aurora, plus faint twilight contrast on the landscape. Early October still has real daylight hours, so it is easier to get oriented and see the terrain than in the deep midwinter months — useful for first-time visitors who want a gentler introduction to the dark season.
What’s running this month
October is early winter. Aurora chasing (Oct–Mar) opens strongly as the nights darken and the polar night begins. Glacier ice caves (Nov–Apr) and snowmobile safaris (Nov–May) begin around the end of the month as snow builds. Husky sledding does not fully start until December. The last boat trips and walrus watching (May–Oct) run early in October before closing. ATV, hiking, and cruises are done for the year.
This makes October’s programme genuinely split. The first part of the month can still offer a boat trip on open water before the fjords freeze, while the end of the month delivers the first aurora-dark nights and the first snow-based outings. The exact timing depends on the year’s snow and ice, so confirm which activities are actually running for your dates rather than assuming the full winter slate is in place — much of it only switches on as November arrives.
Should you come in October?
Come in October if you want to catch the first aurora of the dark season while keeping a little twilight contrast, and you do not mind that the snow programme is only just starting. It suits aurora-focused travellers who like a transitional, quiet island.
Pick a different month if you want the full winter activity slate — husky and prime snowmobile arrive in December and beyond, and daylight returns with snow in March. For the deepest, most reliable darkness for aurora, January gives the most dark hours. For summer wildlife, hiking, and boats under the midnight sun, you have just missed it — see July for next year.
