Nepal has a short pre-monsoon summer during May and June. The monsoon begins from the second or third week of June.

You can expect the temperature to be hot in the lower elevations and warm in the higher altitude during the daytime. There might be some snowfall in the higher mountains than during the summer, as it is much warmer, the snow quicker, which can make the trails wet, muddy and slippery. Be cautious and trek safely. When you come across wet stones/rocks, green or black rocks/trail, muddy trail or roots of trees in the forest – assume it is slippery and trek carefully. You should be able to make most of the favorite trekking trails if you are an experienced hiker except for the less trodden treks such as Upper Dolpo Circuit or Upper Dolpo Traverse because deep snow will make it challenging to get through the passes that are above 5000 meters.

As usual - it pays to invest in proper equipment such as a suitable sleeping bag, a couple of layers of fleece, right thermal underwear, thick hiking socks, gloves, trekking pants, warm hats to name a few essential gears to invest. It is always better to have more than less.

It is good to dress up in layers that you can ‘peel' one at a time when you start to warm/heat up as you begin trekking.

Benefits of Trekking in Nepal Himalaya during the summer.

May/June is the summer season and flowers are in bloom in the middle hills and high hills of Nepal. Rhododendron forests can be very colorful with white, pink and crimson red (Nepal's national flower) flowers in bloom along with Magnolias, wild orchids to name a few. The clouds begin to form in the later part of the day, and it can start raining in the lower altitude and snow in the higher elevations during late afternoon or evening. This is a good thing as it can clear the clouds and clear the clouds for excellent mountain views the next morning.

  • The rain, hail or snow can drop the Rhododendron petals in the higher altitude areas and make the forest floors bright and colorful.
  • Most of the lodges and restaurants will be open during the summer season.
  • Your food should be served faster due to the low number of trekkers.
  • The queue for the shower should be short if at all.
  • You will be warm to hot while hiking in the sunny weather – perhaps you will sweat on the uphill climbs.
  • You will get to meet some other trekkers in the lodges.
  • The Internet speed should be decent due to fewer people logging in.

Can I do a high altitude trek in Nepal during May and June?

You can certainly do a high altitude trek in Nepal during May. It is a better time to do a high altitude trek than during February or March. We do receive some precipitation for a few days every month. We receive heavier snowfalls during February and March rather than in the middle of May and June.
