Lhasa records around 3,000 hours of sunshine a year — more than almost any other city in China — and most of its roughly 440 mm of annual rain falls between June and September, much of it at night. That combination defines Tibet weather: thin, dry air, fierce daytime sun, cold nights, and a monsoon season that interferes with mountain views more than with sightseeing. The two clearest travel windows are late April to early June and September to early November.
The table below gives Lhasa month by month; the sections after it cover the seasons and how Everest, Kailash and Nyingchi differ from the capital.
Lhasa, month by month
| Month | Day high / night low (°C) | Character |
|---|---|---|
| January | 7 / −10 | Cold nights, reliable sun; the quietest month |
| February | 9 / −7 | Losar (Tibetan New Year) season; some businesses pause |
| March | 12 / −3 | Warming and windy; Nyingchi peach blossom begins late month |
| April | 16 / 1 | Season opens; clear peaks, thin crowds |
| May | 20 / 5 | Prime window; Everest views at their most reliable |
| June | 23 / 9 | Warmest days; rain begins late month |
| July | 22 / 10 | Monsoon peak, mostly night rain; green valleys, cloudy peaks |
| August | 21 / 9 | Monsoon continues; Shoton Festival crowds in Lhasa |
| September | 20 / 7 | Rain tails off; second prime window opens |
| October | 16 / 0 | Crystal visibility; the photographers’ month |
| November | 11 / −5 | Cold mornings, empty sites, low prices |
| December | 8 / −8 | Deep off-season; sunny Lhasa days, hard travel out west |
Figures are long-term Lhasa averages; a 20 °C swing between noon and midnight is normal in any month, which is why layers beat any single jacket.
The two windows worth aiming for
Late April to early June pairs warming days with pre-monsoon clarity — Everest’s north face (8,848.86 m) shows most reliably in May, and Saga Dawa, the full-moon festival in May or June, fills the Barkhor with pilgrims. September to early November is the mirror image: the monsoon withdraws, dust has been rained out of the air, and October delivers the sharpest mountain visibility of the year. Both windows suit every standard route, including fixed-departure group tours.
Season by season
Winter (December–February) is underrated for Lhasa itself: sun most days, afternoon temperatures above freezing, pilgrim crowds at the Jokhang rather than tourist ones, and noticeably lower prices. High passes and western Tibet are genuinely hard going, and the Namtso road (4,718 m lake) closes after snowfalls. Spring (March–May) opens with wind and peach blossom in Nyingchi — late March to mid April at around 2,900 m — and builds to May’s clarity. Summer (June–August) is the warmest, greenest and busiest stretch; rain falls mostly at night, but cloud sits on the big peaks more often than not. Autumn (September–November) dries out fast and ends the season on its best visibility.
Beyond Lhasa: how the regions differ
Everest Base Camp (5,150 m, Rongbuk side) runs 15–20 °C colder than Lhasa with wind on top — down jacket territory in any month, and best visited inside the two clear windows. The Mount Kailash kora season runs mid-May to early October; the 5,648 m Drolma La pass holds snow outside it. Nyingchi, at roughly 2,900 m the lowest major stop, is wetter and milder than the plateau proper and peaks early with the peach blossom. Yamdrok Lake (4,441 m) is a day-trip altitude rather than a weather problem — wind and sun are the realities there year-round.
Frequently asked questions
When is the cheapest time to visit Tibet?
November to February. Winter departures price well below the April–October season, Lhasa hotels discount heavily, and sites like the Potala Palace are at their quietest. The trade-off is cold nights around −10 °C, closed high routes such as Namtso, and limited access to western Tibet — but a Lhasa-centred winter itinerary works well.
What is the single best month for Tibet?
For most routes, May or October. May pairs warm days with pre-monsoon Everest clarity and the Saga Dawa festival; October delivers the year’s sharpest visibility after the rain has washed the dust out. June to August wins on warmth and greenery but loses mountain views to cloud more often.
Does the rainy season ruin a summer trip?
No — it redistributes it. Lhasa’s monsoon rain falls mostly at night, mornings are frequently clear, and valleys are at their greenest. What summer genuinely costs you is reliability of big-mountain views: Everest’s face hides in cloud more often in July and August. City, monastery and festival itineraries — including August’s Shoton — lose almost nothing.
When can I see Mount Everest clearly from the Tibet side?
The reliable windows are May and October, with late April, early June and September close behind. At Everest Base Camp (5,150 m, Rongbuk) the north face shows on most clear mornings in those months; in July and August monsoon cloud wins more days than it loses. Dawn beats afternoon for visibility in every season.
How cold does it actually get?
Lhasa winter nights reach about −10 °C while the same January day can hit 7 °C in strong sun — the swing matters more than the lows. Everest Base Camp runs 15–20 °C colder than Lhasa year-round with wind chill on top. Pack layers and a down jacket for any itinerary touching 5,000 m, in any month.
How do I pick my month and start planning?
Decide what the trip is for: mountain views point to May or October, festivals to Saga Dawa in May–June or Shoton in August, budget to winter. Then count the permit clock — scans 20 working days before arrival, four to five weeks of lead time. Send us the month and we return a day-by-day plan priced for it.
