Best Time for Upper Mustang Trek
Updated on July 25, 2025

The Upper Mustang Trek is most enjoyable in the spring (March to May) and autumn (September to November). Clear skies, comfortable temperatures, and breathtaking vistas of the mountains and surrounding landscapes are all features of these seasons. While autumn delivers chilly, dry weather and vibrant celebrations like Tiji, spring brings hills in flower.

Although it can be hot, Upper Mustang is accessible during the monsoon season (June to August) due to its location in a rain shadow, unlike other treks. Winter, which lasts from December to February, is extremely chilly and offers little services. April, May, September, and October are the best months for the most comfortable and picturesque experience.

Every trekker should consider the best time for Upper Mustang Trek before starting their journey. The Upper Mustang differs from other regions of Nepal. The weather can vary rapidly, and the area is windy and dry. Selecting the appropriate season increases your enjoyment of the trek while maintaining your comfort and safety.

Upper Mustang receives less rain since it is located in a unique region known as the rain shadow. Because of this, trekking is feasible even during the summer months when other locations are too damp. However, there are better and worse months.

There are seasons with warm days and clear sky. Some can be very crowded, too windy, or too chilly. Selecting the ideal period for your needs is made easier when you are aware of what each season has to offer. For instance, would you like to witness local events, peaceful trails, or stunning photographs? You can make a decision based on the answer.

I didn't consider the season to be very important when I was planning my personal trip. However, after trekking through chilly nights and strong afternoon winds, I discovered that timing is crucial. This Upper Mustang travel guide is intended to assist you in choosing the ideal time to visit Upper Mustang. 

Weather in Upper Mustang

Compared to other trekking regions in Nepal, Upper Mustang is unique. The weather in Upper Mustang is distinct from the summers in most of Nepal. It is situated in the Himalayan rain shadow, where the large mountains obstruct the rain clouds. Upper Mustang remains dry even during the monsoon season (June to August) when other trails like Everest and Annapurna are slick and wet.

Here, the weather is dusty, bright, and dry. Rainfall is minimal and the skies are frequently clear. Because of this, it's an excellent location for trekking even during rainy seasons in other regions of Nepal. However, especially during the summer, walking may seem hot during the day due to the dry air and strong heat. Nights and mornings are considerably colder. Another major factor influencing the weather is wind; nearly every afternoon, strong winds blow across the valleys, making it difficult to trek if you start too late. With careful planning, trekkers can visit Upper Mustang for the majority of the year due to this unique weather.

Upper Mustang Trekking Season

Best Time for Upper Mustang Trek

Since the region remains dry for the majority of the year, Upper Mustang Trekking is possible in practically every season. The clear, cool weather that is ideal for walking occurs in the spring (March to May) and fall (September to November) seasons. Because Upper Mustang is in a rain shadow and receives little rainfall, the summer months of June through August are also favorable. The coldest season is winter (December to February), when there may be snow in some places and fewer teahouses open. Every season offers something unique, but it's crucial to pick the ideal time of year depending on your trekking expertise and level of comfort.

Upper Mustang Trekking in Spring Season (March to May)

The ideal time to visit Upper Mustang tends to be in the spring. The months of March through May bring pleasant temperatures, clear sky, and a vibrant, light-filled landscape. The dry landscape, serene towns, and vibrant Tibetan culture of Upper Mustang are best experienced during this time of year. Let's examine why spring is such an ideal time of year for this excursion in greater detail.

Why Spring is the Ideal Time to visit Upper Mustang

The weather in Upper Mustang is ideal for trekking in the springtime. It's warm during the day, neither too hot nor too chilly. Since the skies are typically clear and blue, you may take in stunning views of the far snow-capped peaks, red cliffs, and dry valleys.

Even during the summer, Upper Mustang receives little precipitation due to its location in the Himalayan rain shadow. However, after winter, the air feels clean and fresh in the spring, and the paths are dry and pleasant to walk. This time of year, there is relatively little chance of landslides or slippery roads.

A major aspect of the Upper Mustang experience is the wind, which is typically calmer in the morning. You can enjoy peaceful treks through the historic trade routes and high-altitude communities and avoid the strongest afternoon winds if you begin your trek early each day.

Many people believe that if you want a comfortable and safe trip, spring is the best season to visit Upper Mustang because of these wonderful walking conditions.

What Makes the Spring Season Special in Upper Mustang

The splendor of the surroundings is another factor that makes spring the best season to explore Upper Mustang. Despite being primarily arid and desert-like, the region comes alive in the spring. There may be green areas in the farming villages and little wildflowers along the trail. It's also a fantastic time to take pictures. The sky is frequently bright blue, and the morning and sunset light is gentle and golden. 

Spring is one of the greatest seasons to visit Upper Mustang if you're searching for the ideal time to visit. It provides wonderful weather, breathtaking vistas, and an intimate connection to the nature and culture of this undiscovered Himalayan kingdom.

Upper Mustang Trekking in Summer/Monsoon season (June to August)

People frequently worry about heavy rainfall, muddy paths, and cloudy sky when they consider trekking in Nepal in the summer. This is the case for numerous well-known treks, including as Everest and Annapurna. Upper Mustang, however, is distinct. Even during the monsoon season, it receives very little rain because it is located in the Himalayan rain shadow. This is why, the question, when to trek Upper Mustang might also include the summer months.

Let's examine why trekking Upper Mustang during the summer months of June through August could be a wise decision, particularly if you're looking for a more sedate and tranquil experience.

Upper Mustang Climate: Less Rain, More Peace

In Nepal's far north, near the Tibetan border, lies an arid, desert-like region known as Upper Mustang. The majority of the rain is prevented from reaching this region by the steep mountains. Therefore, the Upper Mustang paths remain largely dry and clear during the monsoon season, even while the rest of Nepal is muddy and wet.

This indicates that the trails are somewhat quieter and the views are still stunning. The communities and sceneries are more peaceful because there are less tourists. The summer may be the ideal season for you if you desire a peaceful trip with time to think and take in the scenery.

This is also when the hills start to get a little greener, adding a distinctive splash of color to the otherwise arid Mustang landscape. It's a welcome break from the dry and brown autumnal surroundings, although it's not like the dense jungles of lower Nepal.

Things to Know Before You Go

Although there isn't much rain, monsoon trekking in Mustang can still be difficult in many respects. Daytime temperatures rise, particularly at lower elevations. Dust is blown along the trail by the afternoon breeze and the sometimes intense sun. The worst of it can be avoided by strolling early in the morning and wearing a scarf or mask.

Additionally, during the monsoon, the trip to Upper Mustang may be more difficult. Roads from Pokhara to the starting location may be muddy or blocked, and weather-related delays may affect flights to Jomsom. Just in case, it's a good idea to include one or two extra buffer days in your schedule.

Monsoon Trekking in Mustang may still be a fantastic experience if you plan ahead and have a flexible schedule. There are less crowds, welcoming residents, and open teahouses. Some visitors claim that Mustang's serene, spiritual atmosphere became more apparent to them throughout the summer.

The question, when to trek Upper Mustang, is therefore not limited to spring or fall. June to August is a hidden gem if you prefer a calmer trek and don't mind a little heat.

Upper Mustang Trekking in Autumn Season (September to November)

The Upper Mustang Trek is particularly popular in the autumn. The weather is cold, dry, and ideal for strolling from September to November. It is easy to trek for extended periods of time without worrying about rain or snow at this period since the Upper Mustang climate is clean and stable. Every day, the mountains are visible and the skies are often a vivid blue. This is excellent for taking pictures and taking in Mustang's expansive, open views.

Comfortable daytime temperatures range from roughly 10°C (50°F) in higher locations like Lo Manthang to 15 to 20°C (59 to 68°F) in lower areas like Kagbeni. Particularly in October and November, it can get colder at night, with some locations seeing temperatures close to freezing. However, if you wear appropriate warm clothing, the dry air makes it feel less harsh.

In comparison to the humid air during the monsoon season, the dry air at high elevations also facilitates better breathing. This implies that trekking is more comfortable and that your body can adapt to the greater altitude. For both novice and seasoned trekkers, the autumn climate in Upper Mustang is ideal.

Busy Trails but Great Comfort

Autumn is a popular time of year for trekkers because of the excellent weather. Particularly in October, the paths and teahouses can get a little crowded. This is a great time to visit if you like to meet people from other countries and exchange stories while trekking. However, if you like trekking in peace and quiet, you might want to travel in mid- or late November when the crowds start to thin out.

The majority of teahouses remain open and stocked during the autumn, which is another benefit of trekking during this time of year. Better amenities like warm baths and comfortable rooms will be available, along with a wider selection of cuisine. You may witness village life in full flow during this time of year as the locals are busier harvesting crops and getting ready for winter.

The Tiji Festival is one unique occasion that occasionally takes place in the fall. This vibrant, religious event takes place in Lo Manthang and features rituals, music, and masked dances. Although the celebration often takes place in May, it occasionally takes place in October, depending on the Tibetan calendar. If you're fortunate, you may be able to see this lovely cultural celebration while trekking in the fall.

When to trek Upper Mustang for great weather

When asked about the ideal time to visit Upper Mustang, many people find that autumn is the answer. The pleasant Upper Mustang climate during these months makes trekking much more pleasurable. It's simple to understand why this season is the most popular given the pleasant weather, unobstructed views, and first-rate teahouse services.

Therefore, you need to pack warm clothing and a decent sleeping bag.

Hot showers could not be available due to frozen water and clogged pipes. In certain communities, there may be no phone connection or Wi-Fi, and power outages may occur. You can stay safe and locate open teahouses with the assistance of a knowledgeable local guide.
