Petrozavodsk is the capital city of the Republic of Karelia, Russia, which stretches along the western shore of Lake Onega for some 27 kilometers (17 mi). Population: 261,987.Under the Köppen climate classification, Petrozavodsk experiences a subarctic climate (Dfc), though unlike most localities with this type of climate there is no permafrost and relatively moderate temperatures thanks to the moderating influence of the Baltic Sea and the many nearby lakes. Winters, though long and cold, are mild for the high latitude, while summers are short and warm. Precipitation averages 611 millimetres or 24.06 inches annually.I love you Petrozavodsk.
