When to Visit Lhasa

January brings some of the coldest conditions Lhasa sees, with daytime highs around 8°C (46°F) and nights dropping to -7°C (19°F). Rainfall is essentially zero, and the sky tends to be a deep, clear blue on most days, making this one of the sunniest months even as it's one of the coldest. Crowds are very low, which means the major sites like Potala Palace feel unhurried.

February warms only slightly, with highs reaching around 10°C (50°F) and lows around -4°C (25°F), along with a modest 3mm of precipitation. Tibetan New Year, Losar, typically falls in February or early March depending on the lunar calendar and is one of the most atmospheric events of the year in Lhasa, when the city takes on a festive quality that contrasts sharply with the cold. Crowd level remains low.

March marks the beginning of a real spring transition, with highs climbing to 13°C (55°F) and lows hovering right around freezing at 0°C (32°F). Rainfall stays very light at around 3mm, and the days are long and often sunny. It can feel like Lhasa is just beginning to wake up after winter, and you'll notice more activity in the markets and around Barkhor Street. Crowd level is low to medium.

April settles into the most reliably comfortable stretch of spring, with highs of 16°C (61°F) and lows at 3°C (37°F), cold enough at night to need a proper layer but pleasant in the afternoon sun. Rainfall ticks up to around 8mm for the month, which is still very dry in absolute terms. This is when Lhasa begins attracting more visitors ahead of the early-summer peak. Crowd level is medium.

May feels almost warm in the middle of the day, reaching 20°C (68°F) at the high end, with lows of 7°C (45°F) overnight. Rainfall climbs to around 30mm, and you'll start noticing afternoon clouds building more regularly, occasionally delivering a brief shower. Saga Dawa, the month of the Buddha's birth, enlightenment, and parinirvana in the Tibetan Buddhist calendar, often peaks in May or June and draws enormous numbers of pilgrims to Jokhang Temple. Crowd level is high.

June tips Lhasa into its warmest and wettest stretch, with highs of 23°C (73°F) and lows of 11°C (52°F). The monsoon's influence begins in earnest, bringing around 84mm of rain, mostly in afternoon and evening downpours. Mornings can still be clear and very pleasant. Tourism peaks significantly in June as summer travel from mainland China ramps up. Crowd level is high.

July is typically the wettest month of the year, with around 140mm of precipitation and daytime highs of 23°C (73°F), the same ceiling as June, since the altitude keeps temperatures from climbing higher even in peak summer. Lows sit at 11°C (53°F). The rain gives everything a lush quality that feels almost incongruous on the plateau. The Potala Palace looks striking in the moody light between storms. Crowd level is very high.

By mid-September the skies are often strikingly clear. Temperatures are still comfortable, with highs of 21°C (70°F) and lows of 9°C (48°F). The quality of light at altitude in late September is something you tend to remember. Crowd level is medium.

October is a sharp transition toward autumn, with highs of 17°C (63°F) and lows dropping to 3°C (37°F). Rainfall returns to the same minimal level as April at about 8mm.

December is cold, dry, and quiet in equal measure, with highs of 9°C (48°F) and lows of -6°C (21°F) and virtually no precipitation.
