The south and southeast are warmer and more humid, with year-round rainfall. Winter temperatures vary with latitude and are warmest on the sub-tropical southeast coast, where they average about 60ºF. Summer temperatures are more uniform, rising above 70ºF throughout China. On the southeast coast, the July average is about 86ºF. In the north and west, temperate summers contrast with harsh winters. In northern Manchuria, rivers freeze for five months and temperatures can fall to -13 F. In the deserts of Xinjiang province, temperatures range from -12ºF in winter to 90ºF in summer. Summer and autumn are China's wettest seasons. Only the south and east have wet winters. The winter monsoon, which brings cold, dry air from Siberia, affects the rest of China. Moisture-laden winds from the Pacific during the summer monsoon bring rains to most of the country. Droughts and floods are frequent. The 1960-1962 drought contributed to the famine which killed millions during the Great Leap Forward.
