The weather in the NWT varies significantly from season-to-season. In the summer you can expect highs in the mid to upper 20s Celsius, and in the winter you can expect the temperature to reach below -40 degrees, not counting the wind chill factor.

Aurora Borealis: The Aurora Borealis is a natural phenomenon that appears along a narrow band circling the magnetic North Pole. Much of the NWT lies in this auroral zone, where the lights can often be seen directly overhead. The aurora is best seen during the cool, dark fall and winter nights.
Midnight Sun: At the summer solstice, places above the Arctic Circle in the Northwest Territories (such as lnuvik) enjoy 24 hours of daylight. Yellowknife has approximately 20 hours of daylight in midsummer, with four hours of dusk.
