Planning a trek to Upper Mustang can be a life-changing experience. This isolated kingdom in Nepal, with its dramatic landscapes, ancient monasteries, and unique culture, offers a trekking adventure unlike any other. However, the key to a successful Upper Mustang trek lies in choosing the right time of year. While many consider spring and autumn to be ideal, trekking in July (Summer/Monsoon season) requires careful planning and understanding of the weather conditions. This guide, updated for July 2025, will equip you with all the information you need to decide if a summer trek to Upper Mustang is right for you.
Unlike the Everest base camp trek or the popular Annapurna trek, Upper Mustang sits in a rain shadow. This means it receives significantly less rainfall than other regions of Nepal, even during the monsoon season. This makes it a potentially viable option for trekking when other areas are experiencing heavy downpours. However, don’t be fooled – trekking in July still presents its own set of challenges. Let’s dive into the specifics.
Upper Mustang Weather in July: A Detailed Breakdown
July falls squarely within Nepal’s monsoon season, which typically runs from June to September. While the rain shadow effect shields Upper Mustang from the worst of the monsoon, it’s essential to understand the specific weather patterns you can expect in July 2025.
Temperature and Rainfall
Temperatures in Upper Mustang during July are generally mild and pleasant compared to the lower elevations. Expect daytime temperatures to range from 15°C to 25°C (59°F to 77°F). Nighttime temperatures can drop to around 5°C to 10°C (41°F to 50°F), especially at higher altitudes. While rainfall is lower compared to the Annapurna region, you can still expect occasional showers, particularly in the afternoons and evenings. The average rainfall in Upper Mustang during July is around 50-75mm (2-3 inches), spread out over several days.
Visibility and Cloud Cover
One of the biggest challenges of trekking in July is the increased cloud cover. While the skies might be clear in the mornings, clouds often roll in during the afternoon, obscuring the stunning mountain views. Visibility can be limited at times, especially at higher passes. However, the dramatic landscapes of Upper Mustang, even partially shrouded in mist, can still be incredibly atmospheric and rewarding.
Wind Conditions
The wind in Upper Mustang can be unpredictable. July tends to be less windy compared to the spring and autumn months, but strong gusts are still possible, especially in exposed areas. Be prepared for sudden changes in wind speed and direction.
Is July a Good Time to Trek Upper Mustang? Weighing the Pros and Cons
Deciding whether to trek Upper Mustang in July requires careful consideration of the advantages and disadvantages. Here’s a balanced perspective:
Pros of Trekking in July
- Fewer Crowds: July is the off-season for trekking in Nepal, meaning you’ll encounter significantly fewer trekkers on the trails compared to the peak seasons (spring and autumn). This allows for a more peaceful and solitary trekking experience.
- Lush Landscapes: While Upper Mustang is generally arid, the surrounding lower valleys are lush and green during the monsoon season. This provides a beautiful contrast to the stark landscapes of Upper Mustang itself.
- Lower Prices: Accommodation and transportation costs are generally lower during the off-season, making a July trek more budget-friendly. Expect to negotiate better deals on lodging and porter services.
- Clearer Mornings: Often, mornings are clear and sunny, providing excellent opportunities for photography and enjoying the mountain views before the clouds roll in.
- Wildflowers in Bloom: The monsoon season brings wildflowers to life in the lower valleys, adding a splash of color to the landscape.
Cons of Trekking in July
- Limited Visibility: Cloud cover can obscure mountain views, especially in the afternoons. This is perhaps the biggest drawback of trekking in July.
- Occasional Rainfall: While Upper Mustang receives less rainfall than other regions, you should still be prepared for occasional showers.
- Landslides and Trail Conditions: The monsoon season can increase the risk of landslides and muddy trails, particularly in the lower valleys leading to Upper Mustang.
- Leeches: In the lower valleys, leeches can be prevalent during the monsoon season. Proper precautions are necessary to avoid being bitten.
- River Crossings: Rivers can swell during the monsoon season, making some river crossings more challenging and potentially dangerous.

Safety Considerations for Trekking Upper Mustang in July
Trekking in the monsoon season requires extra precautions to ensure your safety. Here are some essential safety tips:
Travel Insurance
Comprehensive travel insurance that covers helicopter evacuation and medical expenses is absolutely crucial. Ensure your policy covers trekking at altitudes above 3,000 meters (9,843 feet). Read the fine print carefully to understand the policy’s limitations and exclusions.
Hiring a Guide and Porter
While it’s possible to trek independently in Upper Mustang, hiring a local guide and porter is highly recommended, especially in July. A guide can provide valuable insights into the local culture, navigate the trails safely, and assist in case of emergencies. A porter can carry your heavy backpack, allowing you to focus on enjoying the trek. Make sure your guide is certified and experienced in trekking in Upper Mustang.
Packing Essentials
Pack appropriate gear for monsoon conditions, including:
- Waterproof Jacket and Pants: Essential for staying dry during rain showers.
- Waterproof Backpack Cover: Protect your belongings from getting wet.
- Waterproof Hiking Boots: Provide good traction and ankle support.
- Quick-Drying Clothes: Avoid cotton, which takes a long time to dry.
- Insect Repellent: Protect yourself from mosquitoes and leeches.
- Water Purification Tablets or Filter: Ensure you have access to safe drinking water.
- First-Aid Kit: Include essential medications, bandages, and antiseptic wipes.
Acclimatization
Altitude sickness can affect anyone, regardless of fitness level. Ascend gradually to allow your body to acclimatize to the altitude. Drink plenty of water, avoid alcohol and smoking, and listen to your body. If you experience symptoms of altitude sickness (headache, nausea, dizziness), descend to a lower altitude immediately.
Stay Updated on Weather Conditions
Monitor the weather forecast regularly and be prepared to adjust your itinerary if necessary. Consult with your guide and local tea house owners for the latest weather updates and trail conditions. Be aware of the potential for landslides and avoid trekking in areas prone to landslides during heavy rain.
Respect Local Culture
Upper Mustang is a culturally sensitive region with a rich Tibetan Buddhist heritage. Dress modestly, especially when visiting monasteries and religious sites. Ask for permission before taking photos of people or places. Be respectful of local customs and traditions. Support the local economy by purchasing goods and services from local businesses.
