Chengdu Weather

The weather in the mountainous region can be icy cold, but clear, like Tibet, which contrasts almost diametrically with the neighboring mild, humid – and often overcast or outright foggy – weather of the Chengdu Plain to the east that characterizes the city of Chengdu, sometimes likened to the city of London as regards the fog and the drizzly weather. Chengdu gets about 250–300 foggy, cloudy or rainy days each year.

A summary of the weather of Chengdu might read "an early spring, a hot summer, a cool autumn and a warm (relative to surrounding areas) winter". The average mid-winter temperature (January is the coldest month) lies between 3–8 degrees Celsius, while the average summer temperature (July being the hottest month) lies between 22–29 degrees Celsius. Average precipitation (strictly rainfall) for the Chengdu Plain is 1000 mm (about 40 in), which is almost double the amount of precipitation in the Hengduan Mountains to the west.

The best periods to visit Chengdu are from March to June, and September to November. There is substantial rainfall during the rainy season (July and August). Our Chengdu Tours will help you to see the best of Chengdu whatever the weather.


Spring is from March to May. The weather warms up from winter, but with frequent alternative temperature changes. Prepare shirts, thin sweaters and coat for the weather.

Hi Patrick,sorry for being late. I wish you had enjoyed a great journey in China. Cheers:) Whitney Liao replied on 2012-11-21

Hi Patrick, from late Oct. to early Nov. it is the beginning of winter, and the month gets quite cold with an average temperature of 7 ° C (44.6 ° F), and the temperature differences fall between 10 ° C (50 ° F) and 15 ° C (59 ° F).

It is quite important to wear thick clothes such as leather or downclothing, thick woolen sweaters and trousers to stay warm.

You can also bring some food and extra cash for purchasing.
