area as well as the town hall. To the east is the residential area Lia and further up Haugen, which is also the location of the school. Furthest up in the valley is Mine 2b and Nybyen, which is mostly used as student housing. Westwards out of town towards Hotellneset is the airport and Mine 3. The remaining mines are in Adventdalen, to the east of town. Climate Svalbard's climate is a polar tundra climate (Köppen: ET) tempered by the North Atlantic Current. The west coast of Svalbard is the warmest and wettest part of the archipelago (except for Bear Island). This is caused by the convergence of mild and humid air from the south and cold air from the north. Longyearbyen generally has lower humidity than other settlements within the Arctic Circle. Longyearbyen experiences midnight sun from between 18 April and 23 August (127 days), polar night from 27 October to 15 February (111 days) and civil polar night from 13 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 in July 2020 and the coldest was in March 1986. Svalbard and Longyearbyen are among the places in the world that have warmed fastest in the latest decades. The 1991–2020 averages show that mean annual temperature in Longyearbyen has increased by since 1961–1990. With the sea surface temperatures warming, ice formation takes longer in the surrounding waters and thus especially early winter under the polar night warms the fastest due to the shorter ice season. , Longyearbyen is the fastest-warming town in the world. Since 1971, temperatures on Svalbard have risen five times faster than the global average, by roughly four degrees Celsius. Winters now are more than seven degrees C warmer than they were in the 1970s. In 2020, Svalbard recorded its hottest ever temperature, , following 111 months of above-average heat. According to the Norwegian Meteorological Institute, annual precipitation on Svalbard has increased by 30 to 45 percent over the past 50 years, mostly in the form of winter rain. Since 2009, deep permafrost temperatures have increased at rates between 0.06 and 0.15-degree C per year. Although Alert, Canada likely has a lower average UV index, Longyearbyen has the lowest recorded average UV index for any current or
