Hudson Bay
Geography
A line from Nuvuk Point (62°21′N 78°06′W﻿ / ﻿62.350°N 78.100°W﻿ / 62.350; -78.100) to Leyson Point, the Southeastern extreme of Southampton Island, through the Southern and Western shores of Southampton Island to its Northern extremity, thence a line to Beach Point (66°03′N 86°06′W﻿ / ﻿66.050°N 86.100°W﻿ / 66.050; -86.100) on the Mainland. Northern Hudson Bay has a polar climate (Köppen: ET) being one of the few places in the world where this type of climate is found south of 60 °N, going further south towards Quebec, where Inukjuak is still dominated by the tundra. From Arviat, Nunavut to the west to the south and southeast prevails the subarctic climate (Köppen: Dfc). This is because in the central summer months, heat waves can advance and leave the weather cool, where the average temperature of the month is above 10 °C. At the southern end in the extension known as James Bay arises the humid continental climate with a more pronounced and hot summer. (Köppen: Dfb) The average annual temperature in almost the entire bay is around 0 °C (32 °F) or below. Except for the James Bay area the average water temperature is 7 °C (45 °F) to the south in January. Although the difference is small in summer in the extreme northeast, wintery temperatures are four to five degrees colder coming near −27 °C (−17 °F).
