Upper Mustang, a remote and isolated area of Nepal’s Trans-Himalayan region, provides dramatic scenery and a culturally rich Tibetan-influenced landscape with unique weather patterns. Setting up a Jeep tour here involves understanding how each season impacts the experience of visiting. Below is a complete seasonal guide of Upper Mustang with reasons why Upper Mustang is still an incredible place to visit during the monsoon, as well as detailed considerations for each season regarding weather, track conditions, visibility, and the best months for navigation and magnificent views.
Seasonal breakdown
Spring (March to May)
When considering a Jeep Tour of Upper Mustang, spring is undoubtedly the most popular time of year. During spring, Upper Mustang shakes off its winter snow and reawakens with beautiful wildflowers, while enjoying temperatures of daytime that typically hover around 14°C to 20°C with nighttime -7°C to -1°C. Stable weather and minimal precipitation allow visitors to enjoy the spring conditions. Spring provides the best dawn or dusk hours with clear views of the snow-capped peaks of Dhaulagiri, Nilgiri, and Annapurna Range.
Spring is characterized by roadside attractions plus occasional local festivals, such as the Tiji Festival in May providing a special opportunity to see and experience the traditional culture of the local population, and color all while driving and enjoying the cruise.
Monsoon (June to August)
Mustang is a prime summer monsoon destination. Upper Mustang is in the Annapurna rain shadow and receives little to no rain. Daytime temperatures hover over 25°C and drop to 3°C or lower at night. The skies are mostly clear, the air is fresh, and the mountainous spires are very crisp. The spectacular landscape is vibrant and alive: rivers are running, and wildlife is as active as your excursion. Fewer tourists mean quieter walking, and lodges are far less likely to be full.
Although Upper Mustang remains dry, the roads from Pokhara to Kalopani can be severely affected by rain. If the weather is wet, landslides can temporarily block the paths. It is recommended to keep an eye on road conditions and current weather for a couple of days to make sure none of your plans are impacted.
Fall Season (September to November)
The autumn experience is the peak season for Upper Mustang Jeep tours, offering the most reliable and pleasant driving conditions. The monsoon clouds and rain have dissipated, providing steady air, crystal-clear skies, and mostly dust-free roads with day temperatures expected to be 12°C to 20°C and night temperatures ranging from -8°C to -4°C.
The roads are manageable and dust is at a minimum creating safer driving before displaced gravel. Colors and scenery are distinct with bright golden fields and contrasting high mountain views. This time of year has a festive environment allowing trekkers to experience the local festival while exploring. So if you are interested in experiencing the cultural significance of the country, this time provides an opportunity to insight into some of the original cultural practices in Upper Mustang.
Additionally, trekkers can expect a visible environment that provides sweeping views of the massive Himalayan Mountains or the desert-like environment of Upper Mustang. However, it is also very busy, so there are more tourists which increases the accommodation demand.
Winter (December to February)
Winter in Upper Mustang is extremely cold at night with some areas experiencing temperatures below –20°C. Daytime temperatures can be milder, although strong winds and occasional snowfall can occur. Due to the cold desert climate, the area stays dry even in winter, though the surroundings can look beautiful with a blanket of snow.
Due to snow and ice, roads particularly in the higher passes can be dangerous. Some lodges and services will be closed or limited as many of the locals escape the upper Mustang in cold weather. For visitors seeking a different experience and peaceful time out in nature, winter provides a tranquil reflective time with very few tourists.
Why Upper Mustang is great even during monsoon
Upper Mustang is one of the popular trekking destinations in Nepal during the monsoon season because it is located in the rain shadow of both the Annapurna and Dhaulagiri ranges. Most trekking destinations in Nepal suffer from heavy rainfall, muddy and slippery paths, and inclement weather during the monsoon season (from June to August), while the Upper Mustang gets little rain. With very little rain, the trails are not muddy and you can do a Jeep tour or trek with dry feet. Little rain reduces the worry about slipping all over the place, landslides, and leeches which are common issues during monsoon time of year. The weather is splendid while it is warm 13°C to 25°C in the daytime with cool evenings which makes travel desirable.
Another reason to visit Upper Mustang during the monsoon period is visibility. Since there are usually little clouds, travelers will experience uninterrupted views of desert landscapes, wind-formed cliffs, and beautiful peaks like Dhaulagiri, Nilgiri, and Annapurna I.
Furthermore, the landscape is enhanced by beautiful wildflowers and green grasses on the barren landscape shed by these magnificent peaks. Monsoon season does not attract the crowd like in the peak seasons of fall and spring, thus allowing tourists an authentic experience. The peaceful ambiance allows cultural immersion as visitations of monasteries will not be crowded, interactions with locals will be easier to interact with, and more festivities will be open and available for them without significant crowds.
