Inukjuak has a
subarctic climate (
Köppen:
Dfc), with a July average of and February average of . The climate is influenced by the freezing of the shallow
Hudson Bay combined with extremely moderated summers with very pronounced
seasonal lag as the bay thaws. As a result, Inukjuak gets an extremely cold climate for the latitude, especially considering its maritime position. On similar latitudes in
Scandinavia in northern Europe, or the northernmost tip of mainland Scotland the summers are close to warmer and winters are around the freezing point – demonstrating the extreme chilliness of the climate. For example,
Stockholm is warmer annually, in spite of being a full degree farther north. Maritime climates in northern Scotland such as
Thurso even make the mark of being milder annually on the same latitude. Even compared to geographically analogous locations in the
Russian Far East, Inukjuak has an annual mean colder than
Aldan and colder than
Magadan, whilst receiving about an hour less sunshine each day than those two localities. Due to the cold summers, Inukjuak is above the
tree line despite lying more than from the pole. Inukjuak also is significantly colder than locations located substantially further north with warm-summer subarctic climates, being colder than
Yellowknife, colder than
Fairbanks, and colder than
Whitehorse. Temperatures in Inukjuak are below freezing from mid-October to late May – the pronounced seasonal lag means May averages colder than October, April colder than November, and March colder than December. Only during a freakish warm wave on 5 December 1923 has Inukjuak recorded a temperature above between November and April, while January has only topped freezing in 1940. During the early winter snowfall is very heavy, averaging in November but tapering off somewhat as the freezing of Hudson Bay completes and reduces the availability of moisture. The most monthly snowfall has been in November 1933 and the most in one day on 11 November 1934, whilst the highest depth of snow on the ground has been on 14 April 1955. Snow usually melts when temperatures rise above freezing late in May, with typically only remaining on the ground at the beginning of June. Summer weather in Inukjuak, due to the cool Hudson Bay and prevailing cyclonic weather, is generally damp and unsettled, with rainfall especially frequent in August and September as the bay thaws completely: these months expect rain on more than half the days. Occasional spells of hot weather occur when the wind drives air from the hotter continent onto the coast: the record high temperature is on 8 June 1955. By the end of September temperatures are already falling to near freezing and October sees the beginning of the long winter and a return to heavy snow driven by the western side of the
Icelandic Low. == Demographics ==
