Average weather, temperature, rainfall, sunshine hours
Hefei's climate is
temperate, with cold winters and hot, humid and rainy summers.
The city is the capital of the Anhui province and is located in the east of China, at 31 degrees north latitude, on the north shore of Lake Chao, and west of Nanjing and Shanghai.
Winter, from December to February, is quite cold: the average January temperature is 3 °C (37.5 °F). There may be very cold periods, with temperatures around freezing even during the day, and with some chance of snow. The temperature dropped to -13.5 °C (7.7 °F) in December 1991, and to -12 °C (10.5 °F) in January 1984 and in February 2008. In other periods, instead, the temperature becomes mild, around 15 °C (59 °F). At night, fog can form.
Spring, from March to May, is initially mild, and becomes gradually warmer. In May, there are already some hot, summer-like days. Spring is a more unstable season than autumn.
Summer, from June to September, is hot and muggy. Both the heat island effect of the big city and the humidity make the heat uncomfortable, especially in July and August. June is a wet and cloudy month. Periods of good weather can be sweltering, especially in July and August, with highs around 37/38 °C (99/100 °F) or more and tropical nights. The temperature reached 40 °C (104 °F) in August 2003 and in August 2013, and 41 °C (106 °F) in July 2017.
Autumn, in October and November, is initially mild, and gradually becomes cooler, and then quite cold at night by November. This is the time of year when the rains are least frequent.
From time to time, from June to early November,
typhoons, the tropical cyclones of Southeast Asia, can affect this area, though less frequently than in southern China.
Best Time
The best times to visit Hefei are spring and autumn, and in particular, from April to mid-May and from the end of September to the beginning of November. It must be said that spring is rainier, while in autumn, the arrival of a typhoon can not be excluded.
