Manaslu Circuit Trek Monthly Weather Guide

Detailed Overview of the Manaslu Circuit Trek

The Manaslu Circuit Trekis one of Nepal’s most fascinating and off-beat trekking routes, circling the majestic Mount Manaslu (8,163m), the eighth-highest mountain in the world. The trek beautifully combines Himalayan scenery, rich Tibetan-influenced culture, and diverse climatic zones that change dramatically as you ascend. Starting from the lush subtropical valleys of Soti Khola, the trail winds through alpine meadows, glacial valleys, and high mountain passes before concluding at Dharapani.

Unlike the crowded Annapurna and Everest regions, the Manaslu trek offers a more peaceful and authentic experience. However, due to its high altitude and varied terrain, understanding the monthly weather and temperature is crucial to planning your journey safely and comfortably.

The region experiences four major seasons: Spring, Monsoon, Autumn, and Winter, each offering a unique trekking experience. From blooming rhododendrons in spring to crystal-clear mountain views in autumn, every season has its own charm and challenges. Let’s dive into the detailed monthly weather, temperature, and rainfall patterns to help you choose the best time for your adventure.

Is the Manaslu Circuit Trek Safe?

Yes, the Manaslu Circuit Trek is generally safe, provided you trek during the favorable seasons, prepare well, and follow the guidance of licensed guides. Since it’s a restricted area trek, a minimum of two trekkers accompanied by a certified guide is mandatory.

The trail itself is well-established, but certain sections, particularly near Larke La Pass (5,160m), can be challenging due to snow or high winds during winter and early spring. The monsoon months (June–August) bring landslides and slippery trails, making this period riskier.

Altitude sickness is another potential concern since trekkers reach elevations above 5,000 meters. However, with proper acclimatization and gradual ascent, most trekkers complete the journey safely. Hiring an experienced guide, carrying essential medicines, and monitoring your health at higher altitudes are key safety measures.

Overall, with the right timing and preparation, the Manaslu Circuit Trek is one of Nepal’s safest and most rewarding treks, offering an unforgettable combination of nature, culture, and adventure.

Seasonal Weather Patterns and Their Impact on Manaslu Circuit Trekking

Understanding the weather is vital when trekking in the Himalayas. The Manaslu region’s climate ranges from subtropical at lower altitudes to alpine and arctic at higher elevations. Here’s a breakdown of each trekking season and how it impacts your experience.

Spring (March–May): The Blooming Season for Manaslu Circuit Trek

Spring is considered one of the best times to trek the Manaslu Circuit. As winter fades, the trails come alive with rhododendrons, orchids, and magnolias in full bloom, painting the forests in shades of red, pink, and white.

• Temperature:

• Lower region (700m–2,000m): 10°C–25°C
• Higher region (3,000m–5,160m): -5°C–15°C

• Weather: Clear mornings and mild afternoons with occasional light rain in May.

• Highlights: Stunning views of Mount Manaslu, Ganesh Himal, and Himalchuli.

Days are pleasantly warm, and nights are cool but manageable. It’s also the peak climbing season, meaning you’ll encounter other trekkers and mountaineers. With stable weather and good visibility, spring offers the perfect blend of comfort and scenery.

Monsoon (June–August): The Wet and Challenging Season

The monsoon season brings heavy rainfall, making this period less favorable for trekking the Manaslu Circuit. The lower trails become muddy and slippery, and frequent landslides can obstruct paths. However, for those seeking solitude, this is when the region is at its greenest and quietest.

• Temperature:

• Lower region: 20°C–30°C
• Higher region: 5°C–15°C

• Rainfall: 500–700 mm (maximum during July and August)

• Challenges: Leeches, landslides, and cloud-covered mountains.

Although the views are limited due to mist and clouds, post-rain mornings can occasionally reveal breathtaking, crystal-clear scenery. If you decide to trek during this season, pack waterproof gear, sturdy boots, and insect repellent.

For safety reasons, most trekkers avoid Manaslu during the monsoon and choose to trek right after it ends, in early September.

Autumn (September–November): The Prime Trekking Season

Autumn is undoubtedly the best time for the Manaslu Circuit Trek. The monsoon rains leave the air fresh and the landscapes dust-free, offering spectacular visibility of the mountains. The trails are vibrant with festivals like Dashain and Tihar, adding cultural richness to your journey.

• Temperature:

• Lower region: 8°C–20°C
• Higher region: -2°C–12°C

• Weather: Stable, dry, and clear skies with minimal precipitation.

• Highlights: Perfect conditions for photography and high pass crossings.

During this period, you can expect consistent weather, comfortable days, and clear nights, ideal for crossing the Larke La Pass. Tea houses are open, and the trekking community is lively but not overly crowded like the Everest or Annapurna routes. If you seek the perfect combination of comfort, visibility, and safety, autumn is the time to go.

Winter (December–February): The Cold and Serene Season

Winter transforms Manaslu into a snow-clad wonderland. While the lower regions remain accessible, the upper trails, especially near Larke La Pass, experience heavy snowfall, making them difficult to cross.

• Temperature:

• Lower region: 0°C–12°C
• Higher region: -10°C to -20°C

• Weather: Crisp, clear skies with occasional snowstorms.

• Highlights: Fewer trekkers, peaceful lodges, and stunning snowy landscapes.

Only experienced trekkers attempt the circuit during winter. With proper cold-weather gear and guides familiar with the route, trekking is possible up to Samagaun or Samdo, where the views are equally spectacular. Winter treks are rewarding for those who love solitude, but be prepared for freezing nights and potential trail closures beyond 4,500 meters.

Summary: Choosing the Right Time to Trek

Verdict:
The best time for the Manaslu Circuit Trek is Spring (March–May) and Autumn (September–November), offering the most stable weather, vibrant scenery, and safe conditions for crossing high passes.

Manaslu Circuit Trek Temperature Overview

The temperature on the Manaslu Circuit varies greatly depending on the altitude. Lower regions like Soti Khola and Jagat have warm subtropical climates, while higher areas such as Samagaun and Larke La can be extremely cold.

Understanding these variations helps trekkers pack efficiently and layer properly, especially when transitioning from humid forests to icy mountain passes.

Manaslu Circuit Trek vs Annapurna Base Camp vs Everest Base Camp Trek

When planning your adventure in Nepal, you might find yourself comparing three of the most iconic Himalayan routes — Manaslu Circuit Trek, Annapurna Base Camp Trek (ABC), and Everest Base Camp Trek (EBC). While all three offer jaw-dropping mountain vistas and cultural immersion, each trek delivers a unique experience in terms of weather, crowd level, difficulty, and scenery.

1. Scenery and Landscape

• Manaslu Circuit Trek: Offers a blend of remote wilderness and Tibetan-influenced culture. The route circles Mount Manaslu (8,163m) and passes through deep gorges, terraced fields, and high alpine passes. The scenery changes dramatically every few days, from lush subtropical forests to icy mountain deserts.

• Annapurna Base Camp Trek: Known for its diverse ecosystem, ABC features terraced farmlands, bamboo forests, and the iconic Annapurna Sanctuary, surrounded by towering peaks like Machapuchare and Annapurna I.

• Everest Base Camp Trek: Offers panoramic views of the world’s highest peaks, Everest, Lhotse, and Nuptse. The trail includes Sherpa villages, monasteries, and the famous viewpoint of Kala Patthar (5,545m).

2. Difficulty Level

• Manaslu Circuit: Moderate to strenuous. The Larke La Pass (5,160m) poses the toughest challenge due to its steep ascent and unpredictable weather.

• Annapurna Base Camp: Moderate. The trails are well-maintained, and altitude sickness is less of a concern.

• Everest Base Camp: Moderately difficult. High altitude and long trekking days make acclimatization crucial.

3. Weather and Best Time to Trek

All three treks share similar ideal seasons, Spring (March–May) and Autumn (September–November).
However, the Manaslu Circuit is less crowded during these times, offering a more peaceful experience compared to the bustling ABC and EBC trails.

4. Crowd Level

• Manaslu Circuit Trek: Restricted area permit limits the number of trekkers — making it perfect for solitude seekers.

• Annapurna Base Camp: Popular among first-time trekkers and moderately crowded during peak seasons.

• Everest Base Camp: The most popular trekking route in Nepal, often crowded, especially during October and April.

5. Cost Comparison

Verdict:
If you’re seeking a remote, culturally rich, and scenic adventure, the Manaslu Circuit Trek is the perfect choice. It combines the raw beauty of Everest with the comfort of Annapurna — minus the crowd.

6. Can I do the Manaslu Circuit Trek in winter?

Yes, you can, but only up to Samagaun or Samdo. Crossing the Larke La Pass during heavy snowfall is risky. Winter trekking (December–February) offers peaceful trails and clear views, but temperatures drop below -20°C at higher altitudes. If you trek in winter, bring appropriate cold-weather gear and go with an experienced guide.

7. Why do the Manaslu Circuit Trek in Autumn?

Autumn (September–November) is the most popular season for the Manaslu Circuit Trek. After the monsoon, the skies are crystal clear, offering uninterrupted views of the Himalayas. The weather is stable, the air is fresh, and the trail conditions are ideal. Plus, you can witness Nepal’s biggest festivals, Dashain and Tihar, adding a cultural touch to your adventure.

8. Why do the Manaslu Circuit Trek in Spring?

Spring (March–May) brings life and color to the Manaslu region. Rhododendron forests bloom in full vibrancy, wildlife becomes more active, and temperatures are mild. Visibility is excellent, making it perfect for photography and panoramic views of Mount Manaslu and Ganesh Himal. It’s also a great season for those who enjoy botany and biodiversity along the trail.

9. Why do the Manaslu Circuit Trek in Monsoon?

Monsoon (June–August) is generally considered off-season due to rain, leeches, and landslides in lower areas.

The upper Manaslu region (like Samagaun and Samdo) receives less rainfall, making it possible for experienced trekkers to explore with caution and proper gear.

10. Why do the Manaslu Circuit Trek in Winter?

Winter (December–February) transforms Manaslu into a snowy paradise. The trails are peaceful and the views are crystal clear. However, it’s also the coldest season, and snow can block the Larke La Pass. This season is perfect for trekkers who love solitude, tranquility, and photography of snow-draped Himalayan peaks.

Yes, especially above 3,000 meters. Common symptoms include headache, nausea, and fatigue. Preventive measures include slow ascent, hydration, and acclimatization days (usually in Samagaun and Samdo). Always consult your guide if symptoms worsen.
