A continental climate is a type of climate found in the interior of large continents, that is, hot summers with convectional rainfall and very cold, dry winters, with only light falls of snow. Summer temperatures are about 20°C (68°F), and winter temperatures are -10°C to -20°C (14°F to -4°F) in the coldest month. Total annual precipitation is about 500 millimeters (20 inches). The natural vegetation consists of grassland. Areas of continental climate are found in Poland and Hungary, and on the steppes of Russia, and the prairies of North America. In the Southern Hemisphere there are no areas of real continental climate because the land masses are relatively narrow, so that oceanic influences are present throughout.
