Nunavut covers the northernmost and coldest parts of Canada. January mean surface temperatures range from around -20° C at the southern tip of Baffin Island, which is influenced by the Labrador Sea to the southeast, to less than -37° C around Lake Hazen on northern Ellesmere Island. As would be expected, the lowest winter temperatures occur in the northernmost part of the territory, but temperatures almost as low (below -35° C) are experienced in an area west of Wager Bay, almost 2,000 kilometers farther south. This is due to its continental location far from the major oceans.
