European Russia receives some maritime climatic influence from the Baltic and Black seas and the Atlantic Ocean; from the Urals to the Far East, the climate is fully continental. The Pacific Ocean provides the southern Far East with warm, humid monsoon conditions. Winter weather varies from short-term and cold along the Black Sea to long-term and frigid in northern Siberia. Summer conditions range from warm on the steppes to cool along the Arctic coast. Much of Russia is covered by snow for six months of the year, and the weather often is harsh and unpredictable.
