Annapurna Circuit Trek during Winter

The Annapurna Circuit Trek during winter is possible. 

Still, trekkers must prepare for freezing temperatures, snow-covered trails, shorter daylight hours, reduced teahouse services, and the possibility that Thorong La Pass may become temporarily inaccessible.

Winter brings dry weather, quiet trails, clear mountain views, and a peaceful trekking environment across much of the Annapurna region. 

When Is Winter on the Annapurna Circuit?

Winter on the Annapurna Circuit generally lasts from December through February. The lower valleys experience cool days and cold nights, while settlements above 3,000 metres face freezing temperatures, frost, ice, and possible snowfall.

Weather conditions vary considerably by elevation. Lower sections may remain dry and comfortable in the daytime, while high-altitude areas can experience strong winds and temperatures well below freezing.

December, January, and February each provide a different winter trekking experience.

Annapurna Circuit Trek in December

December marks the beginning of the main winter season. Early December can retain some of the stable conditions associated with late autumn, including dry trails, clear skies, and excellent mountain visibility.

The first half of December is generally more manageable than the second half. Daytime walking conditions at lower and middle elevations may remain comfortable when the sun is out, but temperatures fall quickly after sunset.

As the month progresses, nights become colder, and frost becomes more common. Snowfall is possible around Thorong Phedi, High Camp, and Thorong La Pass.

December is often a practical winter month for experienced trekkers because many lodges are still operating after the autumn season.

However, some lodge owners may begin moving to lower elevations later in the month, particularly in smaller high-altitude settlements.

Annapurna Circuit Trek in January

January is generally the coldest and most demanding month on the Annapurna Circuit. Temperatures can fall far below freezing at higher elevations, particularly during the night and early morning.

Lower valleys may still experience sunny days, dry weather, and clear mountain views. However, the upper route can be affected by accumulated snow, frozen streams, hard ice, and strong wind.

Teahouse availability is also more limited during January. Some lodges remain open for winter trekkers and local travellers, while others close because of frozen water systems, reduced supplies, or the seasonal movement of their owners.

Annapurna Circuit Trek in February

February remains a winter trekking month, but conditions often begin to improve gradually as the month progresses. Early February can be almost as cold as January, with snow, ice, and freezing nights affecting the upper route.

Daylight slowly increases during February, and daytime temperatures may become more comfortable at lower and middle elevations. Clear mornings and strong mountain visibility are still common during stable weather.

Late February may provide a better balance between winter scenery and improving trail conditions. However, winter does not end at the same time at every elevation. Snow can remain around Thorong Phedi, High Camp, and Thorong La even when lower villages begin to feel warmer.

Fresh snowfall remains possible throughout the month. A sunny day in the lower valley does not guarantee suitable conditions at the pass.

More lodges may begin preparing for the spring trekking season toward the end of February. Even so, accommodation and food availability should be confirmed before travelling into sparsely populated high-altitude sections.

Annapurna Circuit Weather During Winter

Winter weather on the Annapurna Circuit changes significantly as the route rises from low river valleys to Thorong La Pass at 5,416 metres.

Lower sections generally experience dry and cool conditions, while the upper route faces freezing temperatures, snow, ice, and strong wind. Direct sunlight can make daytime walking feel comfortable, but the temperature drops rapidly in shaded areas and after sunset.

The following temperature ranges are approximate. Actual conditions depend on the month, elevation, sunlight, snowfall, wind, and local weather systems.

Elevation	Typical Daytime Temperature	Typical Nighttime Temperature	Expected Winter Conditions
800–1,500 m	12°C to 22°C	3°C to 10°C	Cool, mostly dry, and comfortable in direct sunlight
1,500–2,500 m	8°C to 17°C	-2°C to 6°C	Cold mornings, mild sunny afternoons, and possible frost
2,500–3,500 m	3°C to 12°C	-8°C to 0°C	Cold days, freezing nights, frost, and occasional snow
3,500–4,500 m	-2°C to 8°C	-15°C to -5°C	Frozen ground, snow, ice, and strong wind
4,500–5,000 m	-8°C to 2°C	-20°C to -10°C	Severe cold, exposed terrain, and possible deep snow
5,000–5,416 m	-12°C to -3°C	-25°C to -15°C	Extreme cold, strong wind, ice, and possible whiteout conditions

These temperatures can feel considerably colder because of wind chill. Trekkers must carry equipment suitable for freezing nights even when the lower route feels mild during the day.

Temperature at Lower Elevations

Lower sections of the Annapurna Circuit are generally cool and dry during winter. Daytime temperatures may feel pleasant when the sun is strong, particularly while walking uphill.

Mornings and evenings are much colder. Frost may form on vegetation, roofs, bridges, stone steps, and shaded trails. Wet surfaces can freeze overnight and remain slippery during the early morning.

Lightweight trekking clothes may be sufficient while walking in direct sunlight, but a fleece or insulated layer should remain easily accessible. Trekkers should change into dry clothing immediately after reaching the lodge because sweat-soaked layers become cold quickly.

Weather in Higher Elevations

Conditions become significantly colder above 3,000 metres. Settlements around the upper Marsyangdi Valley can experience freezing nights, cold wind, snowfall, and extended periods when shaded ground remains frozen.

The air is generally dry, which can increase dehydration without creating an obvious feeling of thirst. Trekkers should drink regularly and protect exposed skin from cold air and strong ultraviolet radiation.

Water pipes, taps, and toilets may freeze in high-altitude teahouses. Lodges may have limited running water, and warm water can cost more because fuel is difficult to transport.

Acclimatization remains essential during winter. Cold weather does not reduce the risk of altitude sickness. Trekkers should ascend gradually, remain hydrated, avoid alcohol, and monitor symptoms carefully above 3,000 metres. Nepal Tourism Board warns that acute mountain sickness can develop at high elevations and recommends using designated routes and trekking in groups.

Weather at Thorong La Pass

Thorong La Pass is the most challenging section of the winter trek. At 5,416 metres, the pass is exposed to freezing temperatures, strong wind, snow, and rapidly changing visibility.

The climb usually begins before sunrise, when temperatures can be at their lowest. Snow may make the route difficult to follow, while ice can reduce traction on steep sections. Deep or windblown snow can also increase the time and energy required to reach the pass.

A crossing should only be attempted when the route is open, weather conditions are stable, and an experienced guide confirms that the trail is manageable.

Trekkers should not continue through heavy snowfall, strong wind, poor visibility, or uncertain trail conditions. Waiting for better weather or returning to a lower settlement is safer than forcing a crossing to maintain a fixed itinerary.

Advantages of Trekking the Annapurna Circuit in Winter

Quieter Trails

Winter is one of the quietest periods on the Annapurna Circuit. Trails, viewpoints, dining rooms, and overnight settlements receive significantly fewer trekkers than during the main spring and autumn seasons.

The quieter environment creates a more peaceful trekking experience. Trekkers can move at a comfortable pace, spend longer at viewpoints, and enjoy the landscape without large groups.

Fewer people also reduce competition for rooms in the teahouses that remain open. However, accommodation should still be confirmed in advance because some high-altitude lodges close during the coldest weeks.

Clear Mountain Views

Winter frequently brings dry air and clear skies. Stable mornings can provide sharp views of Annapurna II, Annapurna III, Annapurna IV, Gangapurna, Tilicho Peak, Chulu peaks, Dhaulagiri, and surrounding Himalayan ranges.

The low humidity often creates excellent long-distance visibility. Snow-covered summits appear especially clear against deep blue winter skies.

Cloud and snowfall remain possible, but prolonged monsoon-style cloud cover is uncommon. Nepal Tourism Board notes that even during severe winter conditions in December and January, bright sunshine and brilliant views can compensate for the cold.

Snow-Covered Landscapes

Snow can transform the upper Annapurna Circuit into a dramatic winter environment. Alpine slopes, stone villages, high passes, and surrounding peaks may be covered in fresh snow.

The contrast between dry lower valleys and snowy high-altitude terrain adds variety to the journey. Frozen streams, frosted forests, and snow-covered prayer flags create scenery that is not normally seen during warmer trekking seasons.

Snow also increases difficulty. Scenic conditions should never be treated as evidence that the trail is safe.

Better Room Availability

The lodges that remain open during winter usually have fewer guests. Trekkers may have more choice of rooms and quieter dining areas in established overnight stops.

Rooms in mountain teahouses are generally not heated. Heating is usually limited to the communal dining room, where a stove may operate during the evening.

A four-season sleeping bag remains necessary because an available room does not guarantee a warm sleeping environment.

More Time With Local Communities

Winter’s slower pace can create more meaningful interaction with lodge owners and residents who remain in the mountain villages.

Quiet dining rooms provide opportunities to learn about seasonal migration, traditional food storage, livestock care, winter agriculture, Buddhist culture, and daily life in isolated Himalayan communities.

Some villages become noticeably quieter because families move to lower elevations during the coldest months. This seasonal change is an important part of the winter experience.

Possible Off-Season Savings

Some accommodation providers, transport services, or trekking companies may offer seasonal flexibility in their rates. However, winter should not automatically be treated as a low-cost trekking season.

Extra expenses may arise from additional lodge nights, route changes, winter equipment, alternative transportation, or delays caused by snowfall.

Trekkers should prioritize suitable equipment and professional support rather than choosing winter only to reduce costs.

Challenges of the Annapurna Circuit Winter Trek

Extreme Cold

Cold is the main challenge of winter trekking. Temperatures can fall well below freezing at night, especially above 3,500 metres.

Cold affects sleep, appetite, hydration, battery performance, and the ability to complete simple tasks. Dressing, packing, and preparing for departure take longer when hands are cold.

Layering is essential. Trekkers should avoid waiting until they feel extremely cold before adding insulation.

Snowy and Icy Trails

Snow and ice can cover the route between Manang and Thorong La Pass. Shaded forest paths, stone steps, bridges, stream crossings, and steep descents may also become slippery.

Trekking poles and traction devices can improve stability. Crampon-compatible equipment may be required when hard ice or deep snow affects the high pass, depending on current conditions and the guide’s assessment.

Walking speed should remain controlled. Rushing on frozen ground creates a greater risk of slipping and injury.

Shorter Daylight Hours

Winter days are shorter than spring, summer, and autumn days. Trekkers have less daylight available for long stages, route delays, and unexpected weather changes.

Daily walks should begin early, but departures should also consider frozen trails and extreme pre-sunrise temperatures.

A reliable headlamp is necessary even when the planned walking time ends before dark.

Reduced Teahouse Services

Most main trekking routes in the Annapurna region are served by teahouses, but winter operations can be limited.

Some lodges close completely, while others operate with fewer staff, reduced menus, limited electricity, and restricted water supplies. Fresh vegetables, fruit, meat, and bakery items may be less available at higher elevations.

Advance communication helps ensure that food and accommodation are available at the next planned stop.

Possible Thorong La Closure

Heavy snowfall, deep snow, ice, strong wind, or poor visibility can make Thorong La temporarily inaccessible.

The pass does not follow a fixed winter opening schedule. Conditions can improve after several clear days and deteriorate again after a single storm.

A complete winter circuit can never be guaranteed before the journey begins. Trekkers must remain prepared to wait, return by the same route, or use an alternative itinerary.

Dehydration and Altitude Sickness

Cold air reduces the desire to drink, but the body continues losing moisture through breathing, sweating, and increased urination at altitude.

Water bottles may freeze overnight or during high-altitude walking. Insulated bottle covers and wide-mouth bottles help reduce freezing.

Symptoms of altitude sickness should never be dismissed as cold, tiredness, or poor sleep. Headache, nausea, unusual weakness, dizziness, confusion, and breathing difficulty require immediate attention.

Winter Transport Disruptions

Snow, ice, landslides, road maintenance, and mechanical problems can affect mountain transport.

Road journeys may take longer, while flights operating through mountain valleys can be delayed by wind, cloud, or reduced visibility.

A winter itinerary should include buffer days before international flights or other fixed travel arrangements.

Annapurna Circuit Winter Packing List

Insulated Clothing

Carry moisture-wicking thermal base layers, a warm fleece, an insulated down or synthetic jacket, trekking trousers, insulated trousers, and a waterproof outer shell.

A warm hat, neck gaiter, insulated gloves, and waterproof over-gloves are essential. Carrying spare gloves is useful because wet or lost gloves can create a serious problem at high altitude.

Clothing should be layered so insulation can be adjusted during steep climbs, sunny afternoons, shaded sections, and cold rest stops.

Winter Trekking Footwear

Use waterproof, insulated trekking boots with strong ankle support and deep tread. Boots should have enough room for warm socks without restricting circulation.

Carry wool or synthetic trekking socks, liner socks, gaiters, and lightweight shoes for use inside teahouses.

Microspikes or another suitable traction system may be necessary on icy trails. Equipment requirements should be based on current route conditions rather than the calendar alone.

High-Altitude Sleeping Equipment

Carry a four-season sleeping bag suitable for temperatures well below freezing. A sleeping bag liner can add warmth and help keep the sleeping bag clean.

Teahouses usually provide blankets, but their availability and condition can vary. Blankets should support rather than replace an appropriate winter sleeping bag.

Keep sleeping equipment dry inside a waterproof bag because damp insulation loses effectiveness.

Sun and Cold Protection

Carry high-SPF sunscreen, UV-protective sunglasses, lip balm, and moisturiser. Snow reflects sunlight and increases exposure to ultraviolet radiation.

A neck gaiter or face covering protects the nose, cheeks, and lips from cold wind. Sunglasses or goggles are especially important when walking across snow-covered terrain.

Safety and Navigation Equipment

Carry trekking poles, a headlamp with spare batteries, a first-aid kit, blister treatment, waterproof document bags, an emergency blanket, a whistle, and a fully charged power bank.

A phone with offline maps is helpful but should not replace a guide or local route knowledge. Cold temperatures reduce battery life, so electronic equipment should be carried close to the body when possible.

A water purification system remains necessary because bottled water may be unavailable or environmentally unsuitable at higher elevations.

Do You Need a Guide for the Annapurna Circuit in Winter?

A licensed trekking guide is required for the Annapurna Circuit under Nepal Tourism Board’s revised TIMS provisions. A guide is particularly important during winter. Snow can hide trail markings, ice can change the safest walking line, and lodge closures may require adjustments to planned overnight stops.

Experienced guides communicate with lodge owners, drivers, authorities, and other trekking teams to obtain current information about snow depth, pass conditions, accommodation, and transport.

Guides also monitor acclimatization, identify possible altitude sickness, manage emergency communication, and help determine whether Thorong La can be crossed safely.

Professional support cannot guarantee stable weather or an open pass. It provides informed decision-making when conditions require waiting, turning back, or changing the route.

FAQs

Is the Annapurna Circuit open during winter?

Yes, the Annapurna Circuit generally remains open during winter, but specific sections may become inaccessible because of snow, ice, strong wind, or poor visibility. The lower and middle route may remain walkable even when Thorong La Pass is closed. Trekkers should check current conditions and maintain a flexible itinerary rather than assuming the full circuit can always be completed.

Is December a good time for the Annapurna Circuit?

December can be suitable for experienced trekkers prepared for cold conditions. Early December often offers clear skies, quiet trails, and relatively manageable snow levels. Conditions usually become colder later in the month. Freezing nights, icy paths, limited lodge services, and snowfall near Thorong La remain possible, so suitable equipment and extra days are necessary.

Can I trek the Annapurna Circuit in January?

The Annapurna Circuit can be trekked in January, but it is generally the coldest and most challenging winter month. Deep snow, ice, lodge closures, and possible Thorong La closure can affect the itinerary. January is most appropriate for experienced trekkers travelling with a licensed guide, proper winter equipment, and enough flexibility to change or shorten the route.

Is February suitable for the Annapurna Circuit?

February can be suitable, particularly toward the end of the month when daylight increases and lower-elevation temperatures begin to improve. High-altitude sections remain cold, and snow or ice can still affect Thorong Phedi and Thorong La. Trekkers should not treat late February as spring and must remain equipped for full winter conditions.

Are teahouses open during winter?

Some teahouses remain open throughout winter, especially in larger settlements, but others close or provide limited services. High-altitude lodges may have reduced menus, fewer staff, frozen water systems, and limited electricity. Accommodation should be confirmed before each stage because normal spring or autumn stopping points may not always be available.
