In page Moscow:

"

Moscow has a humid continental climate (Köppen: Dfb) with long, cold (although average by Russian standards) winters usually lasting from mid-November to the end of March, and warm summers. More extreme continental climates at the same latitude – such as parts of Eastern Canada or Siberia – have much colder winters than Moscow, suggesting that there is still significant moderation from the Atlantic Ocean[citation needed] despite the fact that Moscow is far from the sea. Weather can fluctuate widely, with temperatures ranging from −25 °C (−13 °F) in the city and −30 °C (−22 °F) in the suburbs to above 5 °C (41 °F) in the winter, and from 10 to 35 °C (50 to 95 °F) in the summer.[1]
