Autumn: This can also be a good time to trek because the rain has cleared up, and the weather is usually dry and stable. Think clear skies and beautiful fall colors.

During October Thorong La Pass also seems majestic. It is the main thrilling part and the main appeal of the Annapurna Circuit Trek. Climbing the peak of Thorong La Pass is the most daunting task of Annapurna Circuit Trek. However, once you are on the top of the pass, everything feels worth it.

Unlike other months, October falls in the Autumn season with moderate temperatures. Hence there is no chance of rainfall, however, there is a slight chance of snowfall since it lies at a higher altitude.


The third-best month of Annapurna Circuit Trek is September. There is little possibility of rainfall during September. However, when the middle of September starts the rainfall starts decreasing especially in the higher altitudes.

During September as the days pass, the temperature starts becoming warm. During day time the temperature increases to 15 degrees. This is the reason September is a better month than November. As November begins to start even the day starts to get colder which means in higher altitudes it decreases to cold.

The temperature decreases up to 5 degrees Celsius but it is still warmer than the cold month of November. In Thorong La Pass, the temperature is constantly near three to four degrees Celsius.

The trekking route is less crowded than other months. As the monsoon is beginning to end many trekkers prefer to wait to trek either in late September or the beginning of October.

So during this time if you book early, then you can get a peaceful route. Also, you will be able to get the proper accommodation and food services that you have hoped for.
