Foehn winds may occur in the area all year round. It is a warm and dry wind from the ice cap, which will cause the temperatures to rise 10-12 degrees within a couple of hours. During winter the Foehn can melt snow and ice. Then the cold returns, creating a hard crust of ice on the snow.

Changes in the Climate
In recent years climate changes have generally resulted in milder winters as well as in increased precipitation and wind all year round. This means that these days the Disko Bay is only rarely completely covered with sea ice, which was not the case in the past.
The further north of the polar circle you go, the longer the polar night and the phase of the midnight sun last. At Qaanaaq in the northernmost part of Greenland you will find that the polar night and the midnight sun last for almost four months. In Nuuk, south of the polar circle, you do not see the polar night nor the midnight sun.
