Svalbard's climate is a combination of an Arctic climate
Svalbard's climate is a combination of an Arctic climate tempered by the North Atlantic Current. Nordenskiöld Land is the warmest and wettest part of the archipelago, caused by the convergence of mild and humid air from the south and cold air from the north.
Average summer highs are typically 3 to 7 °C (37 to 45 °F) while average winter highs are −11 to −13 °C (12 to 9 °F). Longyearbyen experiences midnight sun from 19 April to 23 August, polar night from 27 October to 14 February and civil polar night from 14 November to 29 January.
However, due to shading from mountains, the sun is not visible in Longyearbyen until around 8 March. Snow typically covers the town from November to March. The warmest temperature ever recorded in Longyearbyen was 21.3 °C (70.3 °F) in July 1979 and the coldest was −46.3 °C (−51.3 °F) in March 1986. Svalbard and Longyearbyen are among the places in the world that have warmed fastest in the latest decades.
