The Monsoons: Climate change linked to the arrival of the monsoon winds can be felt from the end of May, making the atmosphere unbearable. Heat, humidity and low pressure result in very short storms in Rajasthan and Madhya Pradesh. Monsoon rains move from southwest to northeast. Although a recurrent climatic phenomenon, they are highly unpredictable. After the intense heat in May and June, they provide some respite .
The western desert region is unaffected by the monsoon season (August to mid-September). The Gangetic plain oblong strip that covers the states of Uttar Pradesh and Bihar, experiences heavy rainfall from mid-June to late September. Finally, the Himalayan foothills and coastal eastern states (Bengal, Orissa), along the south-western coast of the subcontinent are the first to be affected by the monsoon, are marked by heavy rainfall from June to September.

At the same time, the North also experiences monsoon, but especially the harsh climate in winter (mid-November to mid-March), makes it difficult to access this region. The tourist area, the Central Valley, has a dry winter but snow is rare. In spring (mid-March to mid-June), the temperatures are very pleasant (average 27 ° C during the day and 18 ° C at night), but on the other hand, do not expect to have a clear view on the high peaks of the Himalayas.
