May is a transition month in Nepal and the start of Summer.
Spring can hang on a little longer but most likely heavy monsoon weather will be moving in though not with very heavy showers. It does however start to get humid at this time of year with plenty of thunderstorms.
If your trek runs from April into May then you'll need to bring rain gear and be prepared for heavy down pours..
For the most part at 2,000m expect day time temperatures of 25+ degrees and temperatures at night around 9 degrees.
May trekking tips
- Bring a light rain jacket and backpack rain cover
- Try to leave earlier in May rather than later
- Dress in Layers
May is a transition month in Nepal and the start of Summer. Spring can hang on a little longer but most likely heavy monsoon weather will be moving in though not with very heavy showers. It does however start to get humid at this time of year with plenty of thunderstorms. If your trek runs from April into May then you'll need to bring rain gear and be prepared for heavy down pours.
Warmer weather continues to build and along with it humidity. Expect 25+ degree* weather in the mountains during the day. During the night temperatures are often around the 8-12 degree range*. More frequent hail showers, thunderstorms or rain can occur.
* weather temperatures and conditions change as you go up in altitude or descend. Likewise there are variations depending on the trek. Always expect passes and base camps to have more extreme conditions. The temperatures listed here are only used as rough indications.
Since publishing my guidebooks we've been keeping an accurate record of both GPS data for trails and the weather to try and help trekkers make decisions.
The following information is correlated based on real trekking guides and trekkers who were in the following areas. The weather data is broken down into the year of the trek, weeks in the month and a note on what a guide or person experienced in terms of weather. We've used EBC, ABC and the APC for weather examples as they cover the widest range of areas.
EBC = Everest Base Camp. ABC = Annapurna Base Camp. APC = Annapurna Circuit. WK = Week.
* Blank years or weeks just means the guide or data is/was not available. It may also mean we've not had the time to update the data here (we have a lot of data on all treks). We are trying to keep this information as accurate as possible. If you are looking for specific data you may contact us, however you can best support this site by purchasing a guidebook first.

This historical climate/weather data may be useful to some but do remember that that the weather can change on an hourly basis in Nepal.
Breathable rain gear is essential. Good strong trekking boots would be advisable due to any rain or mud you might come across. Trekking shirts, shorts, pants and a fleece (for the evenings). Keep in mind that humidity can build up in May with sunny, wet and hot days. Dressing in loose clothing can help with the warmer days. A light sleeping bag is a great addition or a sleeping bag liner.
All accommodation along the trekking routes will be open in May. Accommodation gets less busy along popular trails in May.
Just like accommodation all restaurants will be open in May.
