The monsoon rain starts in mid June and lasts till mid of September. The weather has mixed consequences for touring activities depending upon the activities and altitude. When the monsoon clouds come in, it remains cloudy most of the time even though it doesn’t rain all the time. Some days will have persistent light rain and the other days may see torrential downpour for an hour or two. The increased temperature and humidity will be cooled by the rain. Himalayan peaks could be seen certain times a day from the view points above 3,000 m. There is also guaranteed Everest sightseeing flights leaving everyday from Kathmandu.
Monsoon season in Nepal is also the summer. June, July and August are the hottest months of a year. This is definitely not the best time for many treks in the foothills of the Himalayas. But monsoon rain has less effect on a few trekking routes, Nepal tours and tours of Bhutan and Tibet. While the annual average rainfall of the country is 1600 mm, it is only 300 mm in the trans-Himalayan regions.
In fact summer is the best time to travel to Tibet or Mustang and Dolpo of Nepal, as the monsoon rain has less effects in these trans-Himalayan regions.Similarly, a tour of Nepal and Bhutan that involves driving, heritage sightseeing and cultural immersion activities are less affected by the monsoon rain. Decreased prices, less crowd and the authentic cultural experience are the few benefits of travelling to Nepal during summer.
