table below) or in the high Lapland mountains where polar microclimates exist. On average, most of Sweden receives between of precipitation each year, making it considerably drier than the global average. The south-western part of the country receives more precipitation, between , and some mountain areas in the north are estimated to receive up to . Despite northerly locations, southern and central Sweden may have almost no snow in some winters. Most of Sweden is located in the rain shadow of the Scandinavian Mountains through Norway and north-west Sweden. The blocking of cool and wet air in summer, as well as the greater landmass, leads to warm and dry summers far north in the country, with quite warm summers at the Bothnia Bay coast at 65 degrees latitude, which is unheard of elsewhere in the world at such northerly coastlines. It is predicted that as the Barents Sea gets less frozen in the coming winters, becoming thus "Atlantified", additional evaporation will increase future snowfalls in Sweden and much of continental Europe. Swedish Meteorological Institute, SMHI's monthly average temperatures of some of their weather stations – for the latest scientific full prefixed thirty-year period 1961–1990 Next will be presented in year 2020. The weather stations are sorted from south towards north by their numbers. Extremes Extreme points The extreme points of Sweden include the coordinates that are farthest north, south, east and west in Sweden, and the ones that are at the highest and the lowest elevations in the country. Unlike Norway and Denmark, Sweden has no external territories that can be considered either inside or outside the country depending on definition, meaning that the extreme points of Sweden are unambiguous. The latitude and longitude are expressed in decimal degree notation, in which a positive latitude value refers to the Northern Hemisphere, and a negative value refers to the Southern Hemisphere. Additionally, a negative elevation value refers to land below sea level. The coordinates used in this article are sourced from Google Earth, which makes use of the World Geodetic System (WGS) 84, a geodetic reference system. Latitude and longitude Sweden's northernmost point is Treriksröset, in the Lapland province, where the borders of Sweden, Norway, and Finland meet. The closest Swedish city to the area is Kiruna, which is Sweden's northernmost city. Sweden's southernmost point is in the harbour of the fishing village Smygehuk, near the city of Trelleborg, which borders
