The higher parts of Annapurna Circuit Trek are the most affected by the Winter. Thorong La Pass may receive heavy snowfall at the end of December.

Winter turns most of the mountain and higher parts of Nepal into whitish stones. Most of the Annapurna Circuit trails get flooded by the snowfall. As a result, the high areas like Thorong La Pass are strictly restricted to make an entry. The restriction is only after the heavy snowfall in the higher parts.


January is the central month of Winter and being the midpoint it is also the coldest month of all. With increasing temperature, there is regular snowfall in the higher and some lower parts also. Days become shorter and shorter than usual. Daylight also lowers during the winter.

Days start to get colder day by day with a normal daytime temperature of 1°C to -10°C in the higher areas. Whereas, the lower areas are kind of warmer than the high altitudes as their day temperature gets around 7°C to 12°C. Due to the harsh cold temperatures, the higher regions are not allowed to enter by the local government. And, there is no point of trekking during this month as most of the teahouses get shut down. The trails also become too difficult to walk on because of heavy snowfall.

January and as a whole Winter season is the off-time for trekking in Nepal. But remember, mountains during Winter become over-beautiful by the white-toned snow.

The views after a snowfall are worth bearing and daring the cold adventures. But, it is outrageously difficult to complete the whole circuit trek of Annapurna. Because of that, people like to do city tours rather than trekking in higher areas.
