Trekking in Nepal during September

September is the start of the official peak (best) trekking season in Nepal.

However, it's important to realize that it's also the end of monsoon season which can continue on into mid September. Heavy monsoon rains along with thunderstorms can linger on as the weather cools down to pleasant temperatures for trekking.

 

For those that take the chance at trekking early September there is a chance that your could get open trails with few other trekkers and beautiful views. It's a 70/30 chance in my estimation of rain in early September.

For the most part at 2,000m expect day time temperatures of 24+ degrees and temperatures at night around 11 degrees.

September trekking tips

  • Try to plan your trek from mid-september onwards
  • Bring light rain gear just in case

In early September it's best to avoid remote treks in far west or east Nepal. There's still flooding in these areas and the roads are not considered safe. From mid-September the monsoons should have passed and the trekking season begins in earnest. All treks are now possible from the all-time popular treks like Everest Base Camp and Annapurna Circuit to the remoter treks.


What is the weather like in September for trekking in Nepal?


Heavy monsoon rains hang on for the first week or two in September followed by bright pleasant dry weather which announces the arrival of peak trekking season. Expect 24+ degree* weather in the mountains during the day. During the night temperatures are often around the 11 degree range*.

* 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.


Historical weather data for trekking in September


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.

What trekking clothing is needed during September in Nepal?


A light breathable rain jacket is advisable throughout September just in case there is the odd shower or heavier rain at the start of the month. It can be warm so heavy jackets are often too much unless you are expecting to stay a long time at a base camp. Many trekkers wear shorts during the day then switch over to longer trekking trousers later in the evening. A sleeping bag liner can help with the heat in the evening but a light sleeping bag is best if tea-houses run out of blankets.
