Météo à Manang (Annapurna) en décembre

December and January are the driest and clearest months in Nepal, which is why regulars recommend December over the spring for Annapurna views - more reliably clear daytime skies than April, and quieter trails with it. Down in Pokhara at 800m it is not cold: highs around 15 to 21C, lows near 8C, and late-December trek reports read like a good English spring day. The altitude is where it changes - rooms high on the trail sit near -10C in December and January, so the packing depends entirely on how high you go rather than on the town. Haze is possible but is far less the December problem than it is later in the winter. The record for Pokhara: 16.7C days, 8.4C nights, 11.5 precipitation days, 9.1 hours of sun and AQI 75.

Manang-forum threads on a March visit describe the road here as genuinely now fully vehicle-accessible from Besisahar, posters naming this a real change from the trek-only access of years past. Regulars call crossing Thorung La this early a genuine open question, several posters asking whether the pass at over five thousand meters is realistically crossable by late March. Posters call March genuinely still pre-season for the high route, several regulars naming this why timing needs careful checking before committing to a full circuit attempt. Regulars call side trips from Manang still genuinely worthwhile regardless of pass conditions, several threads naming this a real fallback if the crossing looks too risky. Posters recommend checking current pass conditions with local guides, several regulars calling this standard given how much snow can still block the route this early. The record: 5.6C days, -3.1C nights, 67mm across nearly 13 days and 68 percent humidity.

Manang-forum threads on a September Annapurna Circuit trip describe late-month timing as straddling the shift into the main trekking season, posters calling the trail busy with real competition for rooms. Regulars call showers still a factor into September and October, heavier rainfall raising a real risk of mudslides along parts of the route. Posters recommend booking ahead rather than assuming a room will be available on arrival, several regulars describing this as standard practice for a busy September trek. Regulars call weather here genuinely unpredictable at this elevation, one poster citing a fall storm that dropped over a meter of accumulation in a single stretch. Posters recommend real cold-weather layers and flexible scheduling regardless of exact September dates, conditions capable of shifting a trek's timeline with little warning. The record: 16C days feeling like 16C, 10.5C nights, an extraordinarily high 367.6mm across nearly 29 days and 78 percent humidity.

Manang-forum threads on trekking the Annapurna Circuit and Tilicho Lake during the wetter months call this one of the better monsoon-season choices in Nepal, posters describing the Manang and Jomsom-Muktinath side as sitting in a real rain shadow that gets comparatively little rain even at peak season. Regulars call the stretch below Pisang a real contrast, considerably wetter than the sheltered sections further along. Posters describe the approach after Chame as noticeably drier, conditions more favorable than what trekkers face lower down. Regulars recommend never attempting this route solo, a partner or guide standing advice. Posters call real waterproof layers still essential despite the rain shadow, conditions never fully predictable. Regulars recommend checking trail and weather conditions before committing to a specific itinerary. The record: 16.8C days feeling like 18C, 10.4C nights, an extraordinarily high 402.6mm across nearly 30 days and 89 percent humidity.

Manang-forum threads on a late-February Annapurna Circuit attempt are direct sub-zero daytime readings are entirely possible this high even with clear skies, real cold-weather gear non-negotiable regardless of how the valley looks lower down. Posters call the Thorong La pass a genuine wildcard, closures from accumulation and icy ground a real risk that can derail a crossing. Regulars describe Tilicho Base Camp lodges as commonly closed until late February or March, worth confirming before counting on that route. Posters call winter technically the region's drier season overall, though a system can still disrupt an itinerary. Regulars recommend flexible timing and a real weather buffer for any February attempt. Posters call the lower Annapurna lodges generally still open even when higher passes are questionable. The record: 3.5C days feeling like 2C, -5C nights, a notably high 36.2cm of fresh accumulation and 59 percent humidity.
