The regional variations in the climatic conditions of India happen due to two main reasons: temperature and precipitation. These two elements vary from place to place and season to season:

Temperature: During the summer season, the temperature of the summer season reaches to 50-degrees Celsius, while in hilly regions it stays around 20 degrees Celsius. Similarly, during the winter season, the temperature of Drass, Jammu and Kashmir reaches -45 degrees Celsius, whereas in the coastal regions it remains around 22 degrees Celsius.

Precipitation: In India, the amount, type, and distribution of rainfall vary from place to place. For example, the Himalayan region receives rainfall in the form of snowfall, whereas the rest of the country receives it in the form of rainfall only. During the monsoon season, the Western Ghats and North-East part of India receive rainfall of more than 200 cm, but in the same season, Ladakh and Western Rajasthan receive rainfall of less than 10 cm. Most parts of the country experience rainfall from June to September but the Tamil Nadu coast receives rainfall from October to November. There is a gradual reduction in rainfall from East to West.
