India has a three-season year-  the hot, the wet and the cold.  The best time to visit is during the winter from November to February, except for the Himalayan regions - April to August

• The hot begins in February  and in April- May  with temperatures in Central India about 45° C and above, approaching in some regions  50°C. Beginning of June starts high humidity, short rainstorms and electrical storms. Anybody hope for the heavy monsoon.
  
• The wet finally arrives with the monsoon. The monsoon doesn't really cool. At first you simple trade the hot, dry , dusty weather for hot, humid, muddy conditions. The usual monsoon comes from south-west with heavy rainfalls not all day but every day.
  
• The cold finally starts with the end of the monsoon around October. Everything is still green. The temperatures are delightful, not hot and not to cold. The air is clear. In the south, where it never gets cold, the temperatures become comfortable warm rather than hot
