Winter and spring (January to April): The classic time for dog sledding and ski touring. The sea ice is stable, the days are lengthening, and in March and April you get long sunlit days combined with excellent snow conditions. Temperatures range from -20°C to -5°C. The northern lights are visible from September to March.
Summer (June to August): The ice breaks up and the landscape turns green. Midnight sun from late May to late July means you can hike at any hour. Sea kayaking, hiking, and boat trips are the main activities. Temperatures reach 10-15°C on good days, though cold and fog are common.
September to December: Increasingly dark and cold. The sea ice begins to form in November. This is the shoulder season — fewer visitors, but the combination of early darkness and unsettled weather limits activities. The northern lights are spectacular on clear nights.
Air connections to Kulusuk only operate reliably from May to October. Winter visitors typically fly via Nuuk or use charter arrangements.
