December is covered in full depth in our dedicated Annapurna Circuit Trek December guide — early December specifically offers the most forgiving winter conditions of the entire season.

January is deep winter in every sense: the coldest nights, the highest snow accumulation, and the greatest likelihood that Thorong La is genuinely difficult or temporarily closed after a storm. It's also, the quietest month on the entire circuit — a real trade-off for trekkers who prioritize solitude above almost everything else and who come prepared for serious winter conditions.

February is worth treating as two different months in one. Early February still carries deep winter's harshness, cold, potential snow, real pass risk. By mid-to-late February, conditions typically start easing: temperatures climb gradually, and the back half of the month often delivers the first reliable spring-style crossing windows at Thorong La, sometimes weeks before the trail traffic of March and April arrives. Rhododendrons at lower elevations can even begin budding in the final week. Late February is arguably the most underrated window on the entire winter-to-spring calendar, quieter than anything from March onward, with conditions that are frequently better than January by a wide margin.

Annapurna Circuit Winter Weather

Weather changes as sharply with elevation in winter as in any other season, arguably more so, since the gap between a mild lower valley and a genuinely harsh high pass widens in the cold months.

Lower Marsyangdi valley (Dharapani through Chame) stays relatively mild by day throughout winter, often comfortable in direct sun even in January.

Pisang and Manang turn cold, particularly at night, with daytime conditions still often pleasant when skies are clear.

Yak Kharka and Thorong Phedi/High Camp sit firmly in serious winter territory across all three months, cold days, harsh nights, and rising snow probability with elevation.

Thorong La is where winter's real character shows: extremely cold, wind-exposed, and the point where December, January, and February genuinely diverge from each other in terms of practical crossability.

Muktinath and lower Mustang, in the rain shadow, stay drier than the wetter Marsyangdi side but remain cold and often windy throughout winter.

How Cold Is the Annapurna Circuit in Winter?

Area Winter conditions

Lower valleys Cool to mild in sunny periods, often reaching the mid-teens °C by day

Chame / Pisang Cold mornings and evenings throughout winter

Manang Cold, especially at night, with real daytime relief in direct sun

Thorong Phedi Very cold, commonly well below freezing overnight

Thorong La (5,416m) Extremely cold and exposed — nighttime temperatures commonly fall below −15°C to −20°C, occasionally colder in January specifically

Muktinath / Mustang Cold and often wind

Temperature alone doesn't tell the full story — wind chill at the pass can make the effective cold considerably worse than the air temperature suggests, and this matters across all three winter months, not just the coldest one.

Does It Snow on the Annapurna Circuit in Winter?

Yes, at higher elevations, and the likelihood varies by month. Lower sections mostly stay dry throughout winter. Above roughly 3,500 m, snowfall becomes a real factor, with January carrying the highest accumulation risk of the three months and the greatest chance of a storm significant enough to affect Thorong La directly. December tends to see less accumulated snow, particularly early in the month. February often starts with residual snow from January before conditions ease later on. None of this is guaranteed in either direction for any given year — some winters are milder than others, which is exactly why current, local conditions matter more than a general seasonal statistic.

Can You Cross Thorong La in Winter?

Sometimes, and this is the question the rest of the article really orbits around. Across all three winter months, crossing depends on actual current conditions, not the calendar. December offers the best odds, particularly early in the month. January carries the highest risk of the pass being difficult or temporarily closed after a significant storm. February starts similarly to January but improves as the month progresses, with late February frequently delivering some of the season's most reliable winter crossing windows.

A responsible winter approach to Thorong La means: treating the crossing as conditional rather than fixed, building real buffer days into the itinerary, relying on your guide's current local knowledge rather than a general seasonal reputation, and willing to wait or adjust plans if the day's conditions don't support a safe crossing. If the pass is blocked or looking risky when you're in the area, the Poon Hill section of the wider Annapurna region remains fully accessible and rewarding throughout winter, a useful fallback rather than a consolation prize, with its own spectacular winter mountain views from a much lower, safer elevation.

For the complete elevation profile behind the pass, see our Annapurna Circuit Trek Elevation guide; for the full difficulty picture, see our difficulty guide.

Thorong La Winter Conditions

The pass feels dramatically colder than anywhere else on the route in every winter month, for the same underlying reasons regardless of which month you're in: elevation, wind exposure, and minimal shelter. A clear, sunny morning in Manang says very little about what's happening 1,900 metres higher, conditions at the pass can shift faster and with less warning than they do lower down, and this holds true across December, January, and February alike.

Winter Trail Conditions

Expect real variation by both elevation and specific month. Lower sections generally stay dry and firm across all three months. Middle elevations pick up frost and occasional ice, particularly in shaded sections, more pronounced in January than December. High elevations carry the most month-to-month variation, December's trails are often more passable than January's, while February's trail conditions typically start rough and later improves. Road-transferred sections at either end of the itinerary aren't affected the same way, since they're covered by vehicle.

Winter Daylight

Days are shorter than in autumn or spring throughout the entire winter season, with December and January carrying the shortest daylight windows of the year and February gradually lengthening as it progresses. This changes how you should plan walking hours, particularly on the Thorong La day, where finishing the descent before dark matters more in winter than in any other season. Weather can still deteriorate later in the day regardless of month, and shorter daylight means less margin to recover from a delay.

Is the Annapurna Circuit Open in Winter?

The route itself stays accessible throughout winter, this is different from every individual section being practical to cross on any given day. Lower and middle sections generally remain open and walkable across all three months. The genuine question mark is Thorong La specifically, where a significant snowfall can temporarily close the crossing regardless of which winter month you're in, though the odds of that happening shift meaningfully from December (lower) to January (highest) to late February (improving again). Road access on some sections can provide flexibility if trail conditions shift, but current local information — from your guide, is what actually answers this question for your specific dates.

Accommodation on the Annapurna Circuit in Winter

Teahouses remain open along the established route through all three winter months, but operating patterns genuinely vary more than in peak season. Some smaller or higher-altitude lodges reduce services or close for parts of the winter, heating arrangements differ by location, and dining rooms can run considerably colder than they would in October. This holds across December, January, and February, though it can feel more pronounced in January specifically, when trekker numbers, and with them, the incentive for smaller lodges to stay fully staffed drops to their lowest point of the year. A genuinely warm sleeping bag matters in every winter month, regardless of what a given teahouse advertises.

How Crowded Is the Annapurna Circuit in Winter?

Quiet throughout, with real variation between the three months. December can still carry a little of November's tail-end traffic into its first couple of weeks. January is the quietest month on the entire circuit, solitary trekking, if that's what you're after. February starts just as quiet as January before gradually picking up toward March, meaning late February often delivers a rare combination: improving Thorong La conditions alongside trails that are still close to empty.

Is Winter Good for Beginners?

Possible for a well-prepared beginner, but honestly, this is where winter's difficulty curve steepens noticeably compared to autumn or spring — and the gap widens further from December to January before narrowing again in late February. Cold, potential snow and ice, shorter daylight, and a less predictable Thorong La all raise the bar above what a first-timer faces in October or April. A beginner drawn to winter scenery might do better easing in with early December or late February, rather than the deep-winter conditions of January, or consider a lower-altitude winter option like Poon Hill as an introduction before attempting Thorong La in the cold season. For the complete picture on beginner suitability generally, see our Annapurna Circuit Trek for Beginners guide.

Altitude and Thorong La in Winter

Winter cold doesn't add a separate altitude risk on top of what exists any other month — altitude sickness is driven by elevation and ascent rate, not temperature — but cold does make the practical consequences of a problem more serious, across all three winter months roughly equally. Slower recovery, harder conditions for a guide managing a descent, and less margin generally all raise the stakes of the same underlying risk. Gradual ascent, taking the Manang rest day seriously, staying properly hydrated (harder in the cold), and reporting symptoms honestly all matter exactly as much in January as in December or February.

What to Pack for the Annapurna Circuit in Winter

This is a winter-at-altitude packing list throughout the season, with the heaviest requirements in January specifically:

Clothing: base layers, thermal underwear, a warm fleece or mid-layer, a genuinely warm down jacket, a waterproof and windproof shell, warm trekking trousers, thermal leggings, a warm hat, insulated gloves, and warm socks.

High-altitude and winter essentials: a sleeping bag rated for genuinely cold conditions, sunglasses (snow glare is real), sunscreen, a headlamp with spare batteries, trekking poles, an insulated water bottle, and high-quality waterproof boots with good grip.

Traction: microspikes or crampons, worth having available if current conditions at the time call for them — not something every winter trekker automatically needs, but genuinely useful in a snow-affected January or early February.

Practical: gaiters where trail conditions warrant them, personal medication, and basic first-aid supplies.

This isn't the full packing list — see our general Nepal trekking packing guide for the complete rundown.

Guide and Porter in Winter

A licensed guide has been legally mandatory throughout the Annapurna Conservation Area since April 2023, year-round — and winter is exactly when that requirement earns its keep, across all three months. Local, current knowledge of pass conditions, teahouse operating status, and when to wait versus when to push on matters more in January than in October, and matters more in early February than in late February. A porter is genuinely useful throughout winter, since cold-weather gear — a heavier sleeping bag, more insulating layers, traction equipment — adds real bulk beyond what an autumn pack carries. For full detail on hiring and pricing, see our porter guide; for the guide requirement itself, see our permit guide.

Trekking Without a Porter in Winter

Possible for a well-prepared trekker across all three months, with the same winter-specific catch throughout the season: cold-weather gear takes up more space and weighs more than an autumn kit, making a self-carried pack noticeably heavier in any winter month. Keep the pack as light as practically possible, and carry your own essential warm layers even with a porter, so you're never separated from them on a slow, cold day. For the complete self-carry guide, see Annapurna Circuit Trek Without Porter.

Solo Annapurna Circuit Trek in Winter

Workable throughout winter, and January specifically appeals to solo trekkers seeking real solitude — this is the quietest month on the entire circuit. The trade-off holds across all three months: fewer other trekkers around means less informal backup if something goes wrong, and winter's compounding factors make a guide's judgment more valuable solo or not. Guide and permit requirements are unaffected by season. For the full picture on solo logistics, see our Annapurna Circuit Trek Solo guide.

Winter Itinerary Planning

Itinerary structure follows the same underlying logic in winter as any season — route choice, acclimatization, and pace matter most — but winter specifically rewards genuine flexibility over a rigid schedule, and that need is sharpest in January, moderate in December, and easing again by late February. A weather-related delay at Thorong La is a real, non-trivial possibility across the season, most likely in January. For the full route breakdown, see our Annapurna Circuit itinerary guide, or the current Annapurna Circuit Trek page for the day-by-day structure.

Road Access and Winter Conditions

The modern Annapurna Circuit isn't the remote, no-vehicle-access route older descriptions suggest — road access reaches well into the route on both ends, which matters in winter specifically because it offers a flexibility buffer if trail conditions shift. Places Nepal's itinerary uses road transport throughout (Kathmandu–Besisahar–Dharapani and Jomsom–Pokhara), which sidesteps a real winter complication some other itineraries face: the Jomsom–Pokhara flight route commonly suspends entirely from December through February due to crosswinds and snow. A road-based itinerary simply isn't exposed to that particular winter disruption.

Annapurna Circuit Winter Cost

Package pricing doesn't change by season — Places Nepal's current rate runs $720–$990 per person depending on group arrangement, or $820 flat on a fixed group departure, consistent across December, January, and February alike. Winter isn't automatically cheaper simply because it's quieter; what can add cost is a potential buffer day or two if weather affects the Thorong La crossing (a real possibility in any winter month, most likely in January), plus winter-specific gear an autumn trekker wouldn't need. For the complete cost breakdown, see our Annapurna Circuit Trek Cost guide.
