It is also possible to visit Chitwan from March to May, however the grasses are seen growing longer allowing some of the animals to hide and from June onward it gets very hot and humid.
The summer days are typically hot with 30 degree Celsius on average day temperature. The monsoon usually begins at the end of June and continues until September. The mean annual rainfall is about 2150 mm and during this time of the year rivers are flooded and most of the roads are virtually closed.
