There are two clear seasons for visitors. April and May are the best months for sea-ice travel — sled trips to the floe edge, narwhal-hunting season, 24-hour daylight, dry cold around -15 to -25 C. The ice is stable, the light is extraordinary, and most of the local hunters are out on the ice. July and August are the open-water season — boat trips on Inglefield Bredning, glacier calving at the head of the fjord, midnight sun, temperatures hovering around freezing but bearable.
Avoid the shoulder months: October to March is dark and almost everything outside the village is closed, June is the slushy break-up, and September is unstable weather with no sea ice yet. Polar bears are around year-round; never walk far from town without a guide and a rifle.
