Lhasa Season in September: Early Autumn

September brings the transition from summer to cooler, drier autumn weather in Lhasa. Days remain pleasant for outdoor activities, while nights turn chilly. Precipitation starts to decline after the monsoon peak, resulting in more sunny and stable days ideal for high-altitude sightseeing.

It is widely regarded as one of the best months to visit Lhasa — mild temperatures, excellent visibility, and beautiful early autumn scenery on the Tibetan Plateau.

Cooling but Comfortable Temperatures

September delivers pleasant early autumn weather to Lhasa. Daytime highs often reach a comfortable 19–22°C (66–72°F) under the strong sunshine, with lows around 3–7°C (37–45°F). Midday feels warm and ideal for exploring the city and nearby sites.

As the month progresses, temperatures cool gradually. Highs typically hover around 17–20°C (63–68°F), while lows can fall to 1–5°C (34–41°F) or lower on clear nights. The large day-night temperature difference (often 15°C or more) is typical of the high altitude, so proper layering is essential.

Decreasing Precipitation and Abundant Sunshine

Lhasa sees moderate rainfall in September as the rainy season winds down, averaging about 60–70 mm across roughly 10–15 days, usually in the form of short showers. Rain becomes less frequent toward late September.

Known as the “City of Sunshine,” Lhasa enjoys 7–8 hours of sunshine per day on average. Clear blue skies and excellent visibility highlight the Potala Palace, surrounding mountains, and early autumn landscapes. Strong UV radiation remains a key consideration at this altitude.

Daylight Hours and Sunshine

Daylight remains long, starting at around 12.5 hours early in the month and shortening to about 11.8 hours by late September. With plenty of sunshine and a high percentage of clear days, September provides excellent conditions for photography and outdoor activities.
