Is summer good for trekking the Upper Mustang? (June – August)
When we think of summer in Nepal, we often imagine heavy rainfall, muddy trails, and humid weather. However, Upper Mustang is different—it lies in a rain shadow, meaning it experiences little to no rainfall even during monsoon season. From June to August, while the rest of Nepal faces monsoon downpours, Upper Mustang remains a dry oasis, making it a unique summer trekking destination.

Warm and Dry Weather – Unlike other trekking regions, Upper Mustang remains mostly dry, with daytime temperatures reaching up to 32°C and nighttime temperatures around 21°C.
Lush Greenery & Unique Landscapes – While Mustang is known for its barren beauty, summer months bring a touch of greenery, creating a rare and stunning contrast.

The Yartung Festival (August) – This vibrant cultural festival in Lo Manthang features horse races, traditional dances, and grand celebrations—a must-see event for cultural explorers.
Monsoon in Mustang Nepal
Although Upper Mustang is mostly rain-free, occasional light showers can make trails slightly muddy and affect transportation in lower regions. Be prepared for:
Muddy Trails – Some parts of the trek may be slippery, requiring proper trekking shoes.
Road Challenges – Overland travel may experience minor disruptions due to rain in lower regions.
Unpredictable Weather – While the skies are often clear, occasional rain showers can occur, so packing light rain gear is recommended.
Despite these minor challenges, summer trekking in the Upper Mustang is a rare and rewarding experience, offering stunning landscapes, warm weather, and cultural immersion without the usual monsoon troubles.
Things to Consider for Summer Trekkers
Pack Light but Be Prepared – Wear breathable clothing for warm days and carry a light rain jacket.
Plan for Unpredictability – Be flexible with your itinerary as road and trail conditions can change.
Don’t Miss the Yartung Festival – If you’re trekking in August, plan your trip around this spectacular event for an added cultural experience.
If you’re looking for an off-season adventure with fewer crowds, cultural festivities, and breathtaking landscapes, then Upper Mustang in summer is the perfect trek for you!
