Distribution of Rainfall 

  • The average annual rainfall in India is 118 cm. However, the spatial distribution of rainfall in the country is highly uneven.
  • Annual rainfall in parts of the western coast and northeastern India is more than 400 cm. It is, however, less than 60 cm in western Rajasthan and neighboring Gujarat, Haryana, and Punjab. Rainfall is equally low in the interior of the Deccan plateau and east of the Sahyadris. A third area of low precipitation is located in Jammu and Kashmir, around Leh. The rest of the country experiences moderate precipitation. Snowfall is limited to the Himalayan range.
  • Because of the nature of monsoons, annual rainfall varies greatly from year to year. Variability is high in low-rainfall areas, such as Rajasthan, Gujarat, and the leeward side of the Western Ghats. As such, while areas with high rainfall are prone to flooding, areas with low rainfall are prone to drought.
