The climate of Yancheng is
temperate, with cold, relatively dry winters and hot, humid and rainy summers.
The city is located in Jiangsu Province, at 33 degrees north latitude and about 45 km (28 mi) from the Yellow Sea coast. About 80 km (50 mi) to the southwest is Lake Gaoyou, while to the west is Lake Hongze.
Winter, from December to February, is quite cold: the average January temperature is slightly above freezing.
There may be very cold periods, with temperatures around freezing even during the day, and with some chance of snow. Occasionally, the minimum temperature can drop to -10 °C (14 °F).
In other situations, instead, the temperature becomes mild, around 18/20 °C (64/68 °F).
At night, fog can form.
Spring, from March to May, is initially mild, and becomes gradually warmer. Sometimes it can already get hot: in late April, the temperature can sometimes exceed 30 °C (86 °F), and in May, 35 °C (95 °F). 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.
The periods of good weather can be sweltering, with highs around 37/38 °C (99/100 °F) or more and tropical nights.
Summer is the rainiest season. Sometimes there can be particularly heavy rains.
Autumn, in October and November, is initially mild, and gradually becomes cooler, and then quite cold at night by November.
From July to early October (and occasionally also in the second half of June), Yancheng can be affected by
typhoons, the tropical cyclones of South-East Asia, although this area of China is less exposed than the south.
