Nepal has a typical climate which varies as per its topography and altitude. There is a dry season from October to May and there is the wet season, the monsoon, from June to September. September -November, the start of the dry season, is in many ways the best time of the year in Nepal. When monsoon just ends, the countryside is green and lush. Nepal is at its most beautiful and during this season there are plenty of colourful festivals to enjoy.
