In Chongqing, a great metropolis of south-central China, the climate is temperate, with fairly mild but cloudy winters and hot and muggy summers. A city with a millennial history, today Chongqing is a megalopolis, polluted as often happens in the big cities of China. Because of its position in a plain far from the sea and surrounded by mountains, in summer it is very hot, one of the hottest cities in China, while in the other seasons (but also on summer nights) it is often cloudy and foggy. The city is located at the meeting point between the Jialing and Yangtze rivers.
Here are the average temperatures.

The winter, from December to February, is quite mild, in fact the average January temperature is 8 °C (46.5 °F). However, there may be cold periods, with maximum temperatures fluctuating around 5 °C (41 °F) and sometimes even snowfalls. Anyway, the sky is often cloudy.

The spring, from March to May, is initially mild, and becomes gradually warmer, but also more rainy. In May, there are already some warm and summer-like days, at least as regards to the temperature.

The summer, from June to September, is hot and muggy. The distance from the sea and the humidity make the heat annoying, especially in July and August. There can be oppressive periods, especially in July and August, with highs around 38/40 °C (100/104 °F) and tropical nights. In August 2006, the temperature reached 43 °C (109.5 °F), and there have been 13 days with highs equal to or higher than 40 °C (104 °F). However, July and August are also the (relatively) sunniest months of the year.

The autumn, in October and November, is generally mild, and gradually becomes cooler, and then quite cold at night by November. The rains gradually decrease, but the sun becomes less and less frequent.


The amount of sunshine in Chongqing is very poor: the only months when the sunshine hours exceed 40% (but still remain below 50%) are July and August, while from November to February the sun is almost never seen.
