South Bay (Nunavut)

Coral Harbour

The small Inuit community of Coral Harbour is located on the bay's northern shore, 25.9 km from the mouth of the bay. The bay is notable for its fossilized coral which lends its name to the community.

Climate

Climate data is from Coral Harbour.

The area has a severe subarctic climate (Köppen Dfc), for which it just qualifies due to its 10 C July means. It is a borderline polar climate, which results in barren vegetation. Coral Harbour has never gone above freezing in January, February and March (although the latter has recorded 0.0 C). Due to the frozen nature of Hudson Bay, there is a severe seasonal lag until June despite much sunshine and perpetual twilight at night. Due to the drop of solar strength and the absence of warm water even in summer, temperatures still drop off very fast as September approaches, with only July and August having ever recorded temperatures above 24 C. Cold extremes are severe, but in line with many areas even farther south in Canada's interior. Unlike those areas, Coral Harbour remains beneath -25 C in terms of average high in the midst of winter.

Throughout December 2010 and early January 2011, Nunavut, northern Quebec and western Greenland set many high temperature records. In Coral Harbour, a high of 3.3 C in mid-December broke the old record of 1.7 C set in 1963. The daily minimum temperature on 6 January 2011, was about 30 C-change warmer than normal. The unusual warmth was due largely to an unseasonal area of high pressure over Greenland, and very negative values of the Arctic oscillation and North Atlantic oscillation. Mostly in the 21st century, the conditions have combined to produce an Arctic dipole anomaly that brings warm air to the Arctic regions and cold air to the continents.
