Months to Avoid: When the Weather Takes Over 

Certain months pose significant challenges for trekking the Manaslu Circuit, making them less favorable for most trekkers. During the height of the monsoon season(June-August), heavy rains can transform trails into slippery, muddy paths. These conditions not only make trekking physically demanding but also increase the risk of landslides, particularly on steep or exposed sections of the trail. Additionally, dense cloud cover during this time obstructs mountain views, diminishing the visual appeal of the trek.

Similarly, the winter season (December-February) is marked by extreme cold, with temperatures dropping well below freezing, especially at higher altitudes. Heavy snowfall often blankets the trails, and high mountain passes like the Larkya La may become impassable. These harsh conditions make it difficult for less-experienced trekkers to navigate safely and require advanced gear and preparation for those who choose to attempt a winter trek. These months demand careful consideration and thorough planning if undertaken.
