Which is the Best Time for Trekking in Nepal?

Many consider autumn and spring the best time for trekking in Nepal. However, that is just a subjective opinion. Yes, both seasons have the perks of stable weather, moderate temperatures, and clear skies. But do they match the challenge of the summer? Or do they match the view of the mountains in winter?

The answer is no, meaning the best time for trekking in Nepal depends upon personal preference. Each season has specific pros and cons and offers something others don’t. It entirely depends on what experience you want to take home. So, Let’s explore each season more to determine the ideal season for you.

When is the Best Time for Trekking in Nepal?

Spring (March to May)

The spring season in Nepal starts in March and ends in May. It is the pre-summer/monsoon and post-winter season. Hence, the temperature is neither cold nor hot, especially in the lower regions. The temperature can reach up to 30°C in the lower Terai region. The higher areas experience a temperature of -15°C, especially at night. The rainfall is minimal in spring. However, the lower region in the late may experience high precipitations. 

Here is a table showing the approximate temperatures for the spring season, organized by month and elevation.

Pros of Trekking in Spring

• The temperatures are neither too hot nor too cold, which is comfortable for trekking. This also allows trekkers to pack less clothes, making the backpack light. 
• Blooming rhododendrons, lush greenery, and various species of wildflowers make the trails kaleidoscopic. Wildlife also comes out in spring. 
• The weather is generally stable, with a lower chance of rain or snow, and hence predictable. The sky is also clear, offering clear mountain views. 
• The daylight hours are longer in spring, allowing trekkers to have ample rest while trekking. 

Cons of Trekking in Spring

• Popular trekking routes, such as the Everest Base Camp Trek or the Annapurna Base Camp Trek, will be crowded, so those seeking solitude might find it hard to trek. 
• The high crowd will result in a higher demand for accommodations. So, the teahouses or lodges on the trail will be filled with people, and the chances of finding them will also decrease. 
• In late spring, the lower elevations will experience hotter days, with the possibility of slight rainfall. Moreover, occasional haze or dust can reduce visibility.

Summer/Monsoon (June to August)

Summer is also the monsoon season in Nepal. From June to August, Nepal experiences both scorching temperatures and cooling rainfall. Both conditions are extreme, so many do not recommend trekking during the summer. However, it is not impossible. 

The temperature in the lower elevations can even exceed 30°C. In the higher elevations, the lowest temperature is about -5°C. June to August also experiences an average of about 4,000 mm of rainfall. Below is a table showing the approximate summer/monsoon season temperatures, organized by month and elevation.

Pros of Trekking in Summer/Monsoon

• During the summer/monsoon season, the landscapes are verdant. You will be trekking along the trail with the alive nature, creating a vibrant environment.
• Unlike in the spring, trails are less crowded. So, if you seek a peaceful trekking experience, this is your season. 
• Rain-shadow areas such as Upper Mustang and Dolpo are ideal destinations since they receive little to no rainfall.
• The sound of waterfalls and rivers after rainfall is therapeutic to hear. 

Cons of Trekking in Summer/Monsoon

• The heavy rainfall in the monsoon season results in slippery and muddy trails, which increase the risk of accidents. Moreover, leeches and insects are common in this season. 
• Landslides are common in some regions. Trekking in such areas can be dangerous, and delays can occur.
• The temperature is at its highest this season, and walking can be uncomfortable due to rashes and sweats. 
• Cloudy and foggy conditions often obstruct mountain views, reducing the scenic appeal.

Autumn (September to November)

Moderate temperatures, views, good trails, and festivals align perfectly to make autumn the best trekking season in Nepal. Nature’s golden hue also adds to the trail’s beauty. The monsoon rains wash away the dust and pollution, making the atmosphere clean. The weather is also dry and stable. 

Moreover, festivals like Dashain and Tihar add cultural value to the trek. The temperature in the lower region is between 20-34°C, and it is below 0°C in the higher elevation. Below is a table showing the approximate temperatures for the autumn season, organized by month and elevation.

Pros of Trekking in Autumn

• Autumn is the best time for trekking in Nepal due to stable weather and mild, comfortable temperatures. 
• Autumn is the post-monsoon season, and the visibility is excellently clear. Hence, you will witness the unobstructed mountain views. 
• Major Nepalese festivals like Dashain and Tihar take place during this time, offering cultural experiences.

Cons of Trekking in Autumn

• It is the most crowded trekking season, especially on popular routes like Everest Base Camp and the Annapurna Circuit.
• Due to high demand, accommodation and flights can be more expensive, and finding them can also become problematic. 
• The large crowds on the trails can diminish the true joy of trekking, which is to connect with nature.

Winter (December to February)

Winter Trekking in Nepal is mainly associated with snow fields and white mountains. When it falls upon the mountain, the early sunrise provides views of the golden Himalayas, which is a treat to watch. Snowfall is more common in mountainous regions. 

The temperature during the nighttime is extremely chilly, often reaching below -20°C in the mountains. In such regions, days are also colder than in any other season. However, it is a very comfortable month for lower-elevation treks like Ghorepani Poon Hill. 

Below is a table showing the approximate temperatures for the autumn season, organized by month and elevation.

Pros of Trekking in Winter

• From mountains to lands in the high-altitude, everything is covered in white snow, providing breathtaking scenery and enhancing the overall trekking experience.
• The skies are also clear, allowing you to witness the snow-clad mountains. 
• The trails are often quieter. Hence, you can have an immersive trekking experience. 
• Since the crowd is low, the prices of flight tickets and accommodations go down, offering the budget trekking opportunity. 

Cons of Trekking in Winter

• Temperatures can drop significantly below the freezing point, especially at higher altitudes. Trekking in such cold temperatures is challenging. Moreover, even if you rest for a night, you might not be able to fully recover from the aches. 
• Some high passes, such as Thorong La and Cho La, may be closed due to heavy snowfall.
• Teahouses in remote high-altitude areas may close. If not closed, they will open on a turn-based basis, limiting the food and accommodation options.
• There is an increased risk of frostbite and altitude sickness due to extreme cold.

Conclusion

Autumn offers the clearest skies, breathtaking mountain views, and comfortable trekking temperatures. Spring brings a vibrant touch to the trek with blooming rhododendrons. Winter offers solitude and snow-covered landscapes. Summer, on the other hand, offers rushing streams and verdant greenery. However, each season has certain challenges. So, the best time for trekking in Nepal depends on your preference and available time.

The key to deciding one for yourself is to know what you want. If it is a moderate temperature and clear views, go for either spring or autumn treks. However, if you prefer challenges, both summer and winter treks are your option.
