September, October, and November are the most popular seasons for trekking to Annapurna Base Camp. Trekkers from all over the world come to the Annapurna region this season. This is mainly down to the awesome weather of the Annapurna Region in these months.
The autumn season lies between the summer season that precedes it and the winter season that follows it. So the weather is not as hot as that of the summers and neither is it as cold as the winter season.
The amount of precipitation in these months is also low. All of this culminates in making the Annapurna Base Camp trek popular amongst trekkers all over Nepal and around the world.
Before taking a look at the weather of the various months of the autumn season, let us take at the various seasons of Annapurna Base Camp first. That will give you some idea why the autumn season is so popular amongst trekkers.
Seasons in Annapurna Base Camp
There are four seasons in the Annapurna Region. They are summer, winter, autumn, and spring. The temperature and the weather pattern of all these seasons are quite different. Let us take a look at the characteristics of these seasons in brief.
June, July, and August are the months of the summer season in all of Nepal. This is true of the Annapurna Base Camp as well. The sun beats down in the various places along the Annapurna Base Camp trek. This makes for pleasant trekking conditions as you won’t have to deal with the cold a lot of the time.
Summer season is also the wettest season in the Annapurna Base Camp. The monsoon rain brings quite a bit of rainfall in the Annapurna region in these months. Due to this, your trek might be interrupted. So make sure that you account for such interruptions as well as wet trekking trails.
Winter season, which falls in the months of December, January, and February, is the coldest of all seasons. There might also be some snowfall along the trails, especially in the high altitudes of this trek. As the temperature can be as low as -20 degrees in the Annapurna Base Camp in the winter season, inexperienced trekkers avoid trekking to ABC in the winters. As a result, the winter is an off-season for trekking in the ABC region.
Winter trek to Annapurna Base Camp, however, has its own advantages. The most astonishing views of the mountains, lowest precipitation of all seasons and off-season discount in the winter season makes ABC winter trek pleasurable. Besides, you can deal properly with the cold of the winter season with the appropriate gear.

The spring season is characterized by mild sunshine, low rainfall, clear blue skies, and wonderful mountain views.
