Best Time for Annapurna Circuit Trek (2026): Complete Weather & Seasons Guide
The best time for the Annapurna Circuit Trek is one of the most important factors to consider when planning your Himalayan adventure. Stretching around the Annapurna Massif and crossing the famous Thorong La Pass (5,416 metres), the Annapurna Circuit is one of Nepal’s most diverse and rewarding trekking routes. The trail takes you through lush subtropical forests, traditional Gurung and Manangi villages, alpine meadows, high mountain deserts, and sacred pilgrimage sites such as Muktinath, offering an unforgettable trekking experience.
However, weather conditions on the Annapurna Circuit vary significantly throughout the year. While spring and autumn provide clear skies and ideal trekking conditions, winter brings snow-covered mountain passes, and the summer monsoon creates muddy trails and occasional landslides. Choosing the right season can greatly influence your safety, comfort, mountain views, and overall enjoyment.
Whether you’re a first-time trekker or an experienced hiker, this guide explains the best time for the Annapurna Circuit Trek, including seasonal weather, temperatures, trail conditions, photography opportunities, festivals, and practical tips to help you plan the perfect trek in 2026.
Why Timing Matters for the Annapurna Circuit Trek
Unlike many shorter trekking routes in Nepal, the Annapurna Circuit passes through a wide range of climates and elevations. Starting from around 760 metres in the lower Marsyangdi Valley and climbing to Thorong La Pass at 5,416 metres, trekkers experience dramatic changes in weather and temperature within just a few days.
Choosing the right season helps you:
- Enjoy clear mountain views.
- Cross Thorong La Pass safely.
- Reduce the risk of weather-related delays.
- Experience comfortable daytime temperatures.
- Avoid heavy snowfall or monsoon rains.
- Capture better photographs.
- Enjoy open tea houses and trekking services.
Although the Annapurna Circuit can be trekked throughout most of the year, certain seasons provide significantly better conditions than others.
Annapurna Circuit Weather Overview
The Annapurna Circuit experiences four distinct seasons, each offering a different trekking experience.
| Season | Months | Trekking Conditions |
|---|---|---|
| Spring | March–May | Excellent |
| Summer / Monsoon | June–August | Challenging |

| Winter | December–February | Difficult at higher elevations |
Among these seasons, spring and autumn consistently offer the best combination of stable weather, comfortable temperatures, and spectacular Himalayan views.
Best Time for Annapurna Circuit Trek: Spring (March to May)
Spring is widely regarded as one of the finest seasons for trekking the Annapurna Circuit. As winter snow begins to melt, the trails become more accessible, temperatures gradually rise, and forests burst into colour with blooming rhododendrons.
The weather is generally stable, making it an excellent time for both beginner and experienced trekkers.
Weather During Spring
During spring, daytime temperatures are pleasant at lower elevations, while higher altitudes remain cool.
Typical temperatures include:
- Lower elevations: 15°C to 25°C
- Manang: 5°C to 15°C

Between March and April, forests around Chame, Upper Pisang, and lower sections of the trail become covered in vibrant red, pink, and white blossoms.
Combined with snow-covered mountains, these colourful forests create some of the most beautiful trekking scenery in Nepal.
Pleasant Trekking Temperatures
Unlike winter, spring offers comfortable daytime temperatures that make long trekking days more enjoyable.
Most trekkers only require light layers while walking, although warm clothing remains essential during evenings and while crossing Thorong La Pass.

Things to Consider in Spring
As one of the most popular trekking seasons, spring attracts many visitors.
Popular villages such as:

can become busy, particularly during April.
Booking through a reputable trekking company or reserving accommodation in advance is recommended during peak weeks.
Best Time for Annapurna Circuit Trek: Autumn (September to November)
Autumn is generally considered the best time for the Annapurna Circuit Trek. Following the monsoon rains, the skies become exceptionally clear, temperatures remain comfortable, and mountain views are often at their finest.
This season attracts trekkers from around the world and is regarded as Nepal’s peak trekking season.

Autumn offers stable weather with very little rainfall.
Typical temperatures include:
- Lower elevations: 18°C to 24°C

Trekkers enjoy magnificent views of:
- Annapurna I
- Annapurna II
- Annapurna III
- Annapurna IV

These conditions make autumn particularly suitable for:
- First-time trekkers
- Families

Major Nepalese Festivals
Autumn is also Nepal’s biggest festival season.
Trekkers visiting during September and October may experience:
Nepal’s longest and most important Hindu festival, celebrated with family gatherings, blessings, and traditional celebrations.
Tihar
Known as the Festival of Lights, Tihar features colourful decorations, oil lamps, flower garlands, and cultural performances throughout villages and towns.

Stable autumn weather significantly improves the chances of safely crossing Thorong La Pass, the highest point of the trek.
Morning crossings generally offer:

These favourable conditions make autumn the preferred season for most trekkers.
Things to Consider in Autumn
Because autumn is Nepal’s busiest trekking season:
- Tea houses often fill quickly.

- Popular trekking routes may experience more traffic.
Despite the larger number of trekkers, the excellent weather and spectacular mountain scenery make autumn the favourite season for completing the Annapurna Circuit.
Winter Trekking on the Annapurna Circuit (December to February)
Winter transforms the Annapurna Circuit into a peaceful Himalayan wonderland. Snow-covered mountains, frozen rivers, and quiet trails create a unique trekking experience for those seeking solitude. However, winter trekking requires careful planning, proper equipment, and flexibility, especially when crossing Thorong La Pass (5,416 m).
Although fewer trekkers visit during this season, experienced hikers who are prepared for cold conditions can enjoy some of the most spectacular mountain scenery in Nepal.
Weather During Winter
Winter temperatures vary greatly depending on altitude.
Typical temperatures include:
- Lower elevations: 5°C to 15°C
- Manang: -5°C to 8°C
- Thorong La Pass: -15°C to -20°C (or lower at night)
Strong winds and snowfall are common above 4,000 metres.
Advantages of Winter Trekking

Winter is the quietest trekking season.
Tea houses are less crowded, allowing trekkers to enjoy a more peaceful Himalayan experience.
Crystal-Clear Mountain Views
Winter often offers exceptionally clear skies after snowfall.
Snow-covered peaks create breathtaking views of:
- Annapurna II
- Annapurna III
- Annapurna IV
- Gangapurna
- Dhaulagiri
- Tilicho Peak
- Chulu East
- Chulu West
Better Photography
Fresh snow dramatically enhances the mountain scenery.
Photographers particularly enjoy:

Challenges of Winter
Winter also presents several difficulties.
These include:
- Heavy snowfall
- Extremely cold mornings

- Ice-covered trails
- Limited accommodation in some villages
- Possible closure of Thorong La Pass
Always check local weather forecasts before attempting the pass.
Summer and Monsoon Trekking (June to August)
Summer coincides with Nepal’s monsoon season.
Although this is considered the least popular trekking season, parts of the Annapurna Circuit receive less rainfall than many other trekking regions because the northern section lies within the Himalayan rain shadow.
Nevertheless, trekkers should expect wet conditions at lower elevations.
Weather During Summer
Typical temperatures include:
- Lower elevations: 20°C to 30°C
- Manang: 10°C to 18°C
- Thorong La Pass: 0°C to 8°C
Humidity is highest below Chame.
Advantages of Monsoon Trekking
Despite the rain, summer has several benefits.
Beautiful Green Landscapes
- The valleys become incredibly lush.
- Rice terraces, forests, and waterfalls appear at their most vibrant.
Fewer Trekkers
- Trails are noticeably quieter.
- Tea houses often offer more flexibility and better room availability.
Rain Shadow Region
- Areas beyond Manang, including Yak Kharka, Thorong Phedi, and Muktinath, receive much less rainfall than southern Nepal.
- This makes the upper Annapurna Circuit more suitable for monsoon trekking than many other routes.
Challenges of Monsoon Trekking
Trekkers should also prepare for:
- Heavy rain below Chame
- Muddy trails
- Leeches in forested sections
- Cloud-covered mountain views
- Landslides affecting roads
- Flight and transportation delays
Good waterproof gear is essential.
