Seasons in Rajasthan 

1. Summer Season (March to June) 

2. Rainy Season (July to September) 

3. Winter Season (October to February)

1. Summer Season: Temperature normally, above 30 to 40 degree and in the Western Rajasthan districts such as Jaisalmer, Barmer, Bikaner, Jodhpur, Sriganganagar and Churn temperature are above 40 to 45 degrees. The Thar desert is the hottest region of Rajasthan due to sand because sand gets heated faster and cool faster, hence there is a great difference in day and night temperature. The coldest place in Rajasthan is Mount Abu because of its height.

2. Rainy Season: The monsoon winds bring 90% to 95% rains in Rajasthan in the monsoon season between the months of July to September. Monsoon winds arise both from the Bay of Bengal and the Arabian Sea but the Bay of Bengal Monsoon winds shed more rains mainly in the Eastern Rajasthan. The Arabian sea monsoons shed more rains in the southern Rajasthan. Jhalawar district of Rajasthan gets the highest amount of rainfall (about 100cm). Jaisalmer district gets the least rainfall (about 10cm), Mount Abu gets the maximum rainfall i.e. 150cm. As proceeding towards North-West of Rajasthan from the South-East part, amount of rainfall decreases. The eastern Aravalis receive more than 50cm rains whereas the western part gets less than 50cm. Hence along Aravali equal rain line divides the Rajasthan into two parts.

3. Winter Season: Temperature of Rajasthan decreases gradually in the winter months in Rajasthan, touching O’Centigrade in the Western Rajasthan. Mount Abu remains comparatively cold, due to its height. The sky remains clear. Cold winds coming from the Himalayas are called ‘Cold Waves’.
