India has different climates. In the South, the climate is mainly tropical, which means it can get very hot in summer and cool in winter. The northern part, though, has a cooler climate, called sub-tropical, and even alpine in mountainous regions. The Himalayas, in the alpine climate region, can get extremely cold. There is very heavy rainfall along the west coast and in the Eastern Himalayan foothills. The west, though, is drier. Because of some of the deserts of India, all of India gets rain for four months of the year. That time is called the monsoon. That is because the deserts attract water-filled winds from the Indian Ocean, which give rain when they come into India. When the monsoon rains come late or not so heavily, droughts (when the land dries out because there is less rain) are possible. Monsoons normally come around July - August.
