The best time to trek in Upper Mustang is from October to November and from March to May, when the weather is mild and clear, and the scenic views are at their best. These periods offer the most ideal conditions for trekking, with comfortable temperatures, fewer crowds, and stunning vistas of the surrounding mountains.

* **Autumn (October to November)**: The air is crisp and clear, with wildflowers in bloom, adding vibrant colors to the trek. The weather is usually sunny, with moderate temperatures ranging from 10°C to 20°C (50°F to 68°F).
* **Spring (March to May)**: The weather is mild and pleasant, with temperatures ranging from 10°C to 20°C (50°F to 68°F). The rhododendron forests are in full bloom, creating a breathtaking spectacle of colors.

Trekking during these periods also offers the best views of the surrounding mountains, including the Annapurna and Dhaulagiri ranges. The monsoon season (June to August) can make the trails slippery and difficult to navigate, while the winter season (December to February) can be very cold, with temperatures often dropping below freezing.

Avoid trekking during the peak monsoon season, as the rain can make the trails challenging and the risk of altitude sickness increases. Additionally, the winter season can be harsh, with limited access to teahouses and lodges.
