The climate of Russia is formed under the European peninsula. The enormous size of the country and the remoteness of many areas from the sea result in the dominance of the continental climate, prevalent in European and Asian Russia except for the tundra and the best extreme southeast. Mountains in the south obstructing the flow of cold air masses from the Arctic Ocean and the plain of the south and north makes the country open to Pacific and Atlantic influences. Due to the moderating influence of the Atlantic or Pacific, most areas of the country in European Russia, in the south of West Siberia and in the south of the Russian Far East, including the cities of Moscow and Saint Petersburg, experience a humid continental climate.. Most of Northern European Russia and Siberia between the Scandinavian Peninsula and the Pacific Ocean has a subarctic climate, with severe winters in the inner regions of Northeast Siberia, more moderate elsewhere; the strip of land along the shore of the Arctic Ocean, as well as the Arctic islands, have a polar climate.

A small portion of the Black Sea coast, most notably in Sochi, possesses a humid subtropical climate with unusually wet winters. Winter is dry compared to summer in many regions of East Siberia and the Far East, while other parts of the country experience more precipitation across seasons. Winter precipitation in most parts of the country falls as snow; the region along the Lower Volga and Caspian Sea coast, as well as some areas of southernmost Siberia, possess a semi-arid climate. The city of Kaliningrad has an Oceanic climate due to its mild winters and cool summers. About 65% of the Russian territory is underlain by permafrost
