Chengdu, the capital of Sichuan province in the Sichuan Basin, is known for its humid subtropical climate with mild, overcast winters and hot, rainy summers. The live forecast above shows the city’s typical damp conditions, which persist year-round due to the basin’s geography.
What is Chengdu’s climate like by season?
Winter, from December to February, is cool and often overcast, with average highs around 10–12°C and lows near 3–5°C. Snow is rare, but drizzle is common. Summer, June to August, is hot and humid, with highs averaging 29–30°C and heavy rainfall, especially in July and August. Spring and autumn are transitional, with pleasant temperatures but frequent rain. The city receives about 900–1,200 millimetres of precipitation annually, most of it falling from May to September. For a detailed seasonal outlook, travellers often check the chengdu weather by month to plan their visit.
When to visit and how to prepare
March–April and September–October offer the most comfortable weather for sightseeing, with moderate temperatures and lower humidity. If visiting in November or December, pack layers and a waterproof jacket, as cool drizzle is frequent. January 2026 will likely bring the same mild winter pattern. For short-term planning, a chengdu weather 14 days or chengdu weather 15 days forecast is helpful. The chengdu weather forecast 30 days gives a longer view, though accuracy declines with range. Those coming from a Canadian city like Vancouver will find Chengdu’s winter rain familiar, though summers are much hotter.
Does Chengdu get snow?
Snow is very rare in central Chengdu. The city’s low altitude (about 500 metres) and basin location keep winter temperatures above freezing most nights. A light dusting may occur once or twice a decade, but it melts quickly. For snow, head to the nearby mountains.
How humid is Chengdu in summer?
Summer humidity in Chengdu frequently exceeds 80%, making the heat feel oppressive. July and August afternoons often feel like 35–38°C due to the humidex. Light, breathable clothing and air conditioning are essential during these months.
What is the best time to avoid rain?
The driest months are December through March, though even then skies are often overcast. January and February average only 10–15 mm of rain per month. However, the trade-off is persistent cloud cover and occasional fog.
