Climate of Rajasthan

Climate of Rajasthan

The climate in India varies greatly according to latitude, altitude and season. Similarly, the climate of Rajasthan also varies due to its topography. Rajasthan is one of the driest region in India. Due to its location in the north western part of India, it is more prone to various climatic changes. There are also clear evidences of the advance and retreat of the desert over the last 5000 years from the presence of the fossil sand dunes reaching almost as far as Delhi. The western part of Rajasthan is relatively dry and infertile and mainly consists of the Great Indian Thar Desert. Whereas, the southwestern part of Rajasthan is wet, hilly and fertile.
The climate of Rajasthan varies greatly throughout the state. It is very hot and dry in summer in the desert areas, where dust storms also occur, while it is very cold during the winters. To the west of the Aravali range, the weather is characterized by low rainfall with erratic distribution, extremes of diurnal and annual temperatures, low humidity and high wind velocity. While in the east of the Aravali range, the weather is characterized by relatively low wind velocity and high humidity with better rainfall. The climate of Rajasthan can be divided into four seasons namely Summers, Monsoon, Post Monsoon and Winter.
