Чэнгуань — погода по месяцам

Lhasa-forum threads on Tibet in January describe daytime readings as genuinely milder than the numbers suggest, posters calling the strong high-altitude sun capable of making a cold day feel considerably warmer in direct light. Regulars call warmer layers essential for the nighttime drop, temperatures falling well below freezing after dark. Posters describe December and January as the coldest stretch of the year, though real sunshine remains a near-daily feature despite the season. Regulars call January genuinely rewarding for culture, most Tibetan travel happening in winter with monasteries and streets considerably more active with pilgrim activity than the tourist season. Posters recommend three to five days as plenty for a real feel of the city, fewer crowds meaning no wait at sites like the Potala Palace. Regulars recommend real cold-weather layers regardless of how sunny it looks. The record: 2.2C days feeling like -2C, -10.9C nights, 12.5mm across 5 days and 40 percent humidity.

Lhasa-forum threads on a February visit describe this as genuinely a real window before Tibet's annual closure, posters naming late February through late March as when the region typically shuts to foreign travelers for the Lunar New Year period. Regulars call early February specifically still open, several posters naming this the reason to time a trip carefully around the closure dates. Posters call daytime highs genuinely mild for the season despite cold nights, several regulars naming a range roughly around seven degrees by day with lows dropping toward negative ten. Regulars call winter genuinely low season here, several threads naming few tourists and a more authentic experience as real advantages of visiting now. Posters recommend confirming current closure dates before booking a February trip, several regulars calling this standard given how much the window can shift year to year. The record: 4.2C days, -8.5C nights, 18.9mm across nearly 5 days and 40 percent humidity.

Lhasa-forum threads on Tibet's climate describe March as capable of genuinely warm, sunny days despite the calendar reading winter, though posters call real spring not properly underway until April arrives. Regulars describe the valley floor around Lhasa as staying largely clear of real accumulation even through winter, elevation doing more to explain the thin air than heavy snow cover. Posters recommend real acclimatization time, at least a few days at Lhasa's altitude before attempting anywhere higher, regardless of how comfortable daytime feels. Regulars call nights genuinely cold this time of year, a real contrast to a sunny midday that can feel deceptively mild. Posters recommend April through early November as the broader favorable window, March still workable for thinner crowds over ideal warmth. Regulars call the Potala Palace worth visiting regardless of month. The record: 7.2C days feeling like 5C, -5.9C nights, a low 46 percent humidity and 11 hours of sun.

Lhasa-forum threads on spring travel confirm April is when the season genuinely gets underway, milder conditions replacing the harsher winter cold that lingers into March in central Tibet. Posters describe a real daily temperature swing as the defining feature of the plateau climate, cool mornings before sunrise warming substantially by midday once the intense high-altitude sun is fully up. This sun is genuinely strong, Lhasa's own nickname as the Sunlight City repeated across threads as more than marketing, sunscreen and eye protection essential rather than optional. Posters name April through early November as the broad favorable window for Tibet overall, April sitting at the milder, quieter front edge of it before the wetter July-August stretch and before peak-season crowds build later on. The record: 11.5C days feeling like 10C, -1.2C nights, a notably high 25.2cm of fresh snowfall and 51 percent humidity.

A Tibet-focused operator's June guide describes clear skies and comfortable daytime temperatures as the month's draw, with evenings cooling off but not as sharply as earlier in spring. It frames June as early summer proper — the valleys and meadows turning green, a noticeably different Lhasa than the dry, cold shoulder-season months.

August in Lhasa is comfortable - neither hot nor cold at about 3,650m - and the trade-off is the sky. July and August carry roughly half of Tibet's annual rainfall and there are fewer blue days because of it, though regulars make the point that it mostly falls overnight around Lhasa, Shigatse and Chamdo, and eases through the second half of August. They also rate the plateau at its most beautiful now. The other reasons to come in August are the Shoton and Wangguo festivals; the cost is that this is peak season, crowded and expensive. Sun is fierce at this altitude whatever the cloud - sunscreen is the standing advice. The record: 19.4C days, 10.8C nights, 23.7 precipitation days carrying 155.6mm, 10.2 hours of sun and AQI 43.

Lhasa-forum threads on packing for early September describe conditions as genuinely warm enough during the day, posters citing typical readings between roughly eight and twenty degrees Celsius across the wider region this month. Regulars call UV exposure a real concern despite the mild air temperature, long sleeves and trousers recommended regardless of how comfortable the heat feels. Posters recommend scarves, gloves and a hat for the evening chill, temperature swings here considered genuinely significant between day and night. Regulars call September one of the stronger overall windows for Tibet, several posters listing it alongside late April, May, June and October as the recommended stretch. Posters recommend booking through an established local operator regardless of exact dates, a guide required every day in Tibet under current travel rules. The record: 17.8C days feeling like 18C, 8.4C nights, an extraordinarily high 135.5mm across 22 days and 68 percent humidity.

Forum posters describe December mornings as genuinely nippy (down around -6C) but warming quickly once the sun is up, typically reaching 6-10C by midday under famously clear blue skies with little to no wind - the lack of wind chill and generally dry air are repeatedly cited as making the cold feel much more manageable than the raw numbers suggest. Nights stay cold, but posters note most hotels provide electric blankets, keeping sleep comfortable despite outdoor temperatures. December and January are named as the coldest months of the year here, but posters consistently frame December as a genuinely good time to visit specifically because the usual tourist crowds are absent, offering a quieter, more authentic experience of Lhasa's monasteries and old town.
