- •May and early June can be extremely hot and humid before the monsoon officially sets in, offering very low crowds and prices but challenging conditions.
- •December and January are popular due to pleasant weather and festivals, leading to higher prices and crowds, especially around Christmas and New Year.
- •The shoulder months of October and November offer a good balance, with receding monsoon rains, pleasant temperatures, and major festivals like Diwali.
