Cold

Continental climates are defined in the Köppen climate classification as having a coldest month mean temperature below -3 °C (26.6 °F) or 0 °C depending on which isotherm used for the coldest month and four months above 10 °C. In the Köppen climate system, Continental climates are bordered to the south by Temperate climates or C climates (coldest month above 0 °C, but below 18 °C) and to the north by Boreal climate or E climates (only 1 to 3 months with a mean temperature of 10 °C or 50 °F). Köppen also defined continental climates as having more than 30 days with continuous snowcover on the ground.
