The first thing you need to do when planning a backpacking trip into the Himalayas is figure out the ideal time to trek the Annapurna Circuit. The Annapurna Circuit is an incredible trek that weaves through steep river gorges, stunning high-altitude settlements, beautiful alpine meadows and most importantly, over the challenging Thorong La Pass (also known as Thorung La), which rises to an elevation of 5,416 meters, making it one of the most impressive trek routes on the planet! The weather varies greatly between each season on the Annapurna Circuit trail. Selecting the best season for your trek will most likely be the difference between experiencing some of the best clear mountain views possible and getting caught up in an intense monsoon rainstorm. No matter if you have never trekked before or are a seasoned mountaineer, this guide provides detailed information regarding the four seasons that exist in relation to trekking on the Annapurna Circuit so that you can plan your ultimate adventure on the Annapurna Circuit. Nepal has four distinct trekking seasons as a result of the diverse climate in Nepal, which is created by a combination of the Himalayan rainforest’s rainy shadow effect, as well as the effects of monsoon winds. Each season provides its own unique beauty, challenges and number of trekkers on the trail. By the time you reach the end of this guide, you will have enough information to determine when is the best time for you to trek the Annapurna Circuit based on your individual goals for the trek, your personal physical condition and your individual trekking budget.
Overview of Trekking Seasons in Nepal
Ideal time to trek the Annapurna Circuit
In Nepal, you can choose four seasons for trekking (spring: March-May; Monsoon/Summer: June-August; Autumn: September-November;r and Winter: December-February). Each season will affect trail conditions, visibility, and your overall experience when trekking the Annapurna Circuit; the weather pattern produced by the Himalayan mountain chain is mainly due to the South Asian Monsoon and heavy rainfall occurring in areas to the south, while the Annapurna region’s location lying in a ‘Monsoon Shadow’ affects the amount of rain that falls in places like Manang and Mustang during the summer.
The trekking methods on popular routes such as the Everest Base Camp trek (EBC trek) and the Annapurna Base Camp trek (ABC trek) follow a similar seasonal flow; however, there are additional differences associated with geography, including narrower weather windows near Thorong La Pass (between the Himalayas and the Annapurna Mountain Range) and the higher altitude gains of the Annapurna Circuit.
Best Time to Trek the Annapurna Circuit:
At a Glance:
Best overall months: October and November (autumn) | March and April (spring)
Best for mountain views: October–November
Best for fewer crowds: March and December (shoulder months)
Best for budget travellers: June–August (off-season discounts) or winter
Annapurna Circuit Trek in Spring (March–May)
Spring recreation in the Annapurna Circuit offers a rewarding experience in the lower elevation temperature ranges from 10ºC – 20ºC during the day, the wild rhododendron forests explode with red, pink and white blooms, and there are Clear Mornings where you’ll have great views of Annapurna I (8,091m), Annapurna II, Dhaulagiri and Machhapuchhre (Fishtail) above the table mountains. Moderate numbers (notably less than in peak fall) make it a good time to find lodge space on trekking routes without pre-bookings. In the late Afternoon there are often clouds and the potential for light showers developing as early monsoonal moisture moves north. Photographers have great opportunities to take advantage of the available colour in the landscape, as these flowers give tremendous depth of field in front of the mountain.
Who is going to want to Trek during Spring? First-Time Trekker’s looking to experience their first trek to the Himalaya, families and anyone else who enjoys colourful scenery and yet still have great views of the mountains. If the Annapurna Circuit is your ultimate goal, the Annapurna Base Camp Trek is an excellent place for your springtime warm-up.
Annapurna Circuit Trek in Autumn (September–November)

The best time for trekking around the Annapurna Circuit is in autumn,n and there are good reasons for this! Once the monsoon rains have finished, the sky clears to an amazing bright blue colo, ur and you can see for hundreds of kilometres with incredible, unobstructed views of the entire Annapurna mountain range. The temperature is pleasant; warm during the day and chilly at night, and the tracks are in excellent condition due to the rain compacting the dust.
The months from October to November are the peak months to trek. The lodges have plenty of supplies; the trek is busy with trekkers but does not feel unmanageable, and Thorong La Pass can be crossed by trekkers of average fitness. The fresh post-monsoon landscape and the vibrant festival perioDashainain and Tihar) contribute to a rich cultural atmosphere which can only be experienced at this time of year.
Similar to trekking to Everest Base Camp (EBC), autumn attracts the largest number of trekkers worldwide. Prices for lodges are at their highest during this peak window, so it is recommended to book your accommodation in advance, especially in popular places like Muktinath and Manang. Despite the crowds, autumn remains the best season for first-time trekkers or seasoned trekkers who are looking to cross high passes.
Annapurna Circuit Trek in Winter (December–February)
To trek the Annapurna Circuit in winter requires exceptional planning because of the ruggedness of the area and the chance of encountering bad weather. The temperatures above 3,500 meters can plummet to -10°C or lower; the Thorong La Pass can become totally enveloped in snow after a severe snowstorm and might not be crossed for days. Properly equipped with cold-weather gear, having experience at high altitudes, and paying particular attention to the weather, the trek will be successful.

In addition, there are great benefits to winter trekking as well. The trails will be virtually empty, and you will have a greater chance of getting that almost meditative experience of being in the Himalayas. There will be some clear days between storms, giving you approximately two extraordinary views; many of the lodge owners will have more time on their hands to talk with you about the local area; and you can expect substantial discount rates on all of your accommodations and services during this slow time of year.
Winter trekking is appropriate for the experienced trekker who has previously completed difficult treks such as the Langtang Valley trek or Manaslu Circuit trek and enjoys solitude while trekking alone and is comfortable with navigation in the snow. If you have trekked in high altitudes and would like to try another high-altitude trek, the Annapurna Circuit in winter would make an excellent challenge.
Annapurna Circuit Trek in Summer / Monsoon (June–August)
Most Nepalese trekking routes are considered off-season between June and August due to heavy rains, muddy trails, leeches, landslides and low visibility. Therefore, trekkers should not attempt the most popular treks, like the Ghorepani Poon Hill, during this period.
However, due to the monsoon’s effect on Nepal, the Annapurna Circuit’s upper route and the Manang Valley and Mustang region fall in the rain shadow area of the Himalayas and will not experience heavy rainfall. Despite the massive amount of rain that southern Nepal experiences, which can be very wet and muddy, the high-altitude semi-arid region above Chame into Manang is generally dry. Trekkers will experience the lush green of lower valleys, massive waterfalls and blooming areas in high meadows along the route; therefore, those willing to accept the mud and leech conditions from June to August may receive stunning views of the mountain scenery that they have been waiting for.
Experienced trekkers who are travelling along the circuit from the Manang side and have proper waterproof gear can successfully trek through the summer months, as well as budget-conscious travellers who can pay the lowest accommodation and flight prices of the year duringthe monsoon.
Annapurna Circuit Weather by Month:
Understanding the Annapurna Circuit weather by month helps you plan your trek with precision. Here is a concise monthly overview:
January–February: Cold, snowy at altitude. The Thorong La crossing is risky. Quiet trails. Clear skies between snowfall.
March–April: Warming days, rhododendron blooms, good visibility, moderate trekkers.
May: Pre-monsoon warmth, occasional haze and afternoon clouds building. Still good for trekking.
December: Cooling fast, fewer trekkers, still manageable conditions early in the month.
Factors to Consider When Choosing Your Trekking Time
Factors beyond the weather may influence when the best month to visit the Annapurna Circuit is for you. For example, altitude experience and fitness levels are important factors. First-time trekkers should choose either spring or autumn when conditions tend to be very good. Budget-minded trekkers can save the most money in the shoulder months of early March, late November, or in the winter months. October offers great panoramic views of the mountains for photographers, while the rhododendron flowers blooming in spring provide equally beautiful photos.
Cultural events can add to the experience of your trek and provide you with lifelong memories beyond the scenery. Experiencing Dashain in October and Tihar (Festival of Lights) in November in remote villages in the Himalayas provides wonderful experiences that will be remembered long after the trek is done. The cost and availability of permits to trek the Annapurna circuit do not fluctuate throughout the year. The prices for lodging and flights fluctuate and account for the major variance in price by season.
Best Time for Specific Trekking Goals:
Best Time for Beginners
The months of October and November provide excellent introductory trekking conditions with good weather, plenty of staff in lodges, and clearly marked trails. The second-best time to go is in the spring from late-March through mid-April.
Best Time for Photographers
In October, the mountain background is very clear, and then inAprili,l the first rhododendrons are blooming. Many photographers do two trips to the Annapurna circuit — one in the spring and one in the fall.
Best Time for Solo Trekkers
If you are a solo trekker who wants to have some time alone on the trail, then try to trek in December-January or June (only the upper section). You will have the trail nearly to yourself, and the locals will give you a more personal experience.
Best Time for High-Pass Crossings
The safest and easiest times to cross Thorong La Pass are in October-November or March-May. Don’t even think about attempting the pass alone in January or February unless you have the expertise to do so, and don’t try the pass during the monsoon because of the potential for rockfall and trail washing out.
