Summer Treks in Nepal - Advantages and Disadvantages, Weather and Temperature, and 10 Best Summer Trekking Trails
Nepal offers some of the best summer treks, taking you to the arid desert-like landscapes of the Tibetan plateau and some rain shadow areas. Summer or Monsoon season (June to August) is not considered the ideal time for trekking in Nepal with its monsoon rains, several regions remain perfect for exploration. Nepal has many rain shadow areas resulting from the huge mountains that block the moisture-carrying clouds in the Dhaulagiri, Dolpo, Manaslu, Mustang, and even parts of the Annapurna region resulting in clear skies and less precipitation.
Trekking seasons in Nepal come with advantages and disadvantages. The main advantages of the summer trek in Nepal are vibrant atmospheric colors, lush green landscapes, clear skies, and fewer crowds on the trail making it an ideal season for trekking. Highlighting disadvantages, the lower altitude region on the trek route can be extremely warm and hot. Heavy rainfall can cause floods and landslides with leeches throughout the trail.
Nepal experiences the hottest climate during the summer/monsoon season. It is hot, humid, and wet, which may not be the ideal trekking season for most of the trek routes in Nepal. Expect a daytime temperature of more than 30°C (86°F) and a nighttime temperature drop minimum of 14°C (68°F) to 30°C (86°F).
Advantages and Disadvantages of Summer Treks in Nepal
Advantages of Trekking in Summer/Monsoon Season
Green Scenery and Blooming Flowers
In summer, monsoon rains make the hills and mountains very green. Trekking through these lush forests and seeing wildflowers can be amazing. Imagine walking through a huge, colorful garden – that's what summer treks are like.
Fewer Crowds
In summer, there are fewer tourists on the popular trekking trails like Annapurna Circuit and Upper Mustang Treks. This means more peace. You can enjoy the mountains without the busy crowds. It feels like having the trails to yourself, making the experience more personal.
Lower Costs and Better Availability
With fewer trekkers around, accommodation and services are more readily available. Prices for lodges, teahouses, and other accommodations tend to be lower. This can make summer treks a more economical choice, especially for budget-conscious adventurers.
Rich Cultural Interactions
Villagers are less busy with tourists during the summer, offering more opportunities for genuine cultural exchanges. Witness traditional farming practices, participate in local festivals, and experience the daily lives of Nepal’s rural communities.
Disadvantages of Summer/Monsoon Trekking in Nepal
Monsoon Rains
One big problem with trekking in summer is the heavy rain. Trails can get muddy and slippery, which makes walking hard. Rain can also cause landslides and block roads, leading to delays. It is important to be ready for wet weather and have the right gear.
Leeches and Bugs
Wet weather brings out leeches and other insects. This can be annoying for trekkers. Even though leeches are not dangerous, they can be a bother. Wearing long sleeves and using bug spray can help keep them away.
Cloudy Skies
In summer, clouds often cover the mountains, hiding the beautiful views. If you want to see clear views of the Himalayas, summer might not be the best time. But when the skies do clear, the views are even more special.
Heat and Humidity
Lower elevations can be hot and humid during the summer months. This can make trekking physically demanding, especially for those who are not familiar with such conditions. Staying hydrated and taking breaks is essential to manage the heat.

Tips for Summer/Monsoon Season Trekking in Nepal
Trekking in Nepal during the summer season can be a thrilling yet challenging adventure. While the monsoon brings lush greenery, it also presents unique obstacles. Check out some essential tips to make your summer trekking experience in Nepal memorable and enjoyable.
Embrace the Weather and Be Ready for the Rain
Nepal's summer season, typically from June to August, is marked by monsoon rains. These rains can be both a blessing and a curse. While they rejuvenate the landscapes, they also make trails slippery and challenging. Always carry a waterproof jacket and sturdy trekking boots with good grip.
Pick the Right Trekking Route
Not all trekking routes in Nepal are suitable for summer. Some trails become treacherous due to landslides and swollen rivers. Opt for regions in the rain shadow areas, like Upper Mustang or the Annapurna Circuit, where the impact of monsoon is less severe. These areas not only offer safer paths but also stunning, undisturbed views.
Start Early, Finish Early
Mornings are usually dry and clear compared to afternoons. It often rains in the afternoon. Begin your trek early to make the most of the pleasant weather and avoid afternoon rains. Plus, starting early means you can reach your destination in time to relax and enjoy the local hospitality.
Protect Yourself from Leeches
Leeches are common during the rainy season. They like damp places. Wear long sleeves and pants. Use salt or insect repellent to keep them away. Keeping a small packet of salt handy can help remove any leeches that latch on.
Stay Hydrated and Eat Well
The humid weather can make you thirsty. Carry a reusable water bottle and refill it when you can. Use purification tablets or a portable filter if needed. Snack on energy bars, nuts, and dried fruits to keep your energy up.
Respect Local Culture and Customs
Nepal has a rich culture. You will pass through many villages with their own traditions. Show respect by learning a few basic phrases in Nepali, dressing modestly, and asking for permission before taking photographs. Engaging with locals can make your trek more enjoyable and provide valuable insights into their way of life.
Be Prepared for Change
Monsoon weather can be unpredictable. Flights might get delayed, and trails might be blocked. Always have a flexible itinerary and be prepared for sudden changes. It is a good idea to keep extra days in your schedule to accommodate any unexpected delays.
Hire a Local Guide
A local guide can be very helpful during the rainy season. They know the trails and weather well. Guides can also enhance your experience by sharing stories, pointing out interesting flora and fauna, and helping you navigate tricky parts of the trail.
Conclusion
Exploring Nepal during the summer offers a unique experience, with fewer crowds and lush, vibrant landscapes. The best summer or monsoon treks in Nepal are found in regions that lie in the rain shadow of the Himalayas, ensuring drier and more stable trekking conditions.
