Best months for Trekking in Nepal:
Which are the best months for trekking in Nepal? The answer is: it depends…
Usually Spring (March through May) and Autumn (October and November) are considered the best times for trekking in Nepal. However, it is recommended to wait until Summer to trek in the rain-shadow regions such as Upper Dolpo and Upper Mustang.
Officially, Monsoon begins around June 7 and lasts until around October 2. And Winter lasts from late November to February. So, technically, avoiding these months is advised. But, in 2022, the monsoons extended well into the Autumn season causing landslides in the Manaslu region and in other places. And in 2023, even until February, which is well past peak Winter it didn’t snow in most high places of Nepal besides light snow in Western Nepal. So one should expect variations every year.
List of treks and ideal month for trekking:
According to my experience, the following are the best months for trekking in Nepal. Let me qualify the following list by mentioning that due to the recent changes in climate, historical patterns do NOT hold and one-off weather induced events are now becoming more common.
Annapurna Skyline Trek: January, February, March, April, May, October, November and December.
Annapurna Base Camp Trek: March, April and October, November and December (Avalanches can be an objective risk in the Summer – late April, May and June)
Annapurna Circuit Trek: April, May, June, October and November.
Gokyo Lakes Trek: March, April, May, October, November, December.

Remember, if your trek involves crossing a high pass (besides the Renjola and Chola passes in the Everest region which are quite busy), try to plan your trip for late April and May or late October and November. If your trek involves trekking in the high rain-shadow regions of Nepal (Upper Dolpo and Humla), plan for those treks in late May through early October.
