Timeframe of Typhoon Season in Jiangsu
Jiangsu Province is located on the eastern coast of China, within a region frequently influenced by Northwest Pacific typhoons. Based on long-term climate patterns, typhoons affecting Jiangsu are mainly concentrated between June and October each year, with July, August, and September being the most active period for typhoon activity, commonly known as the "peak typhoon season." In rare years, the outer cloud bands of typhoons may affect the province in May or November, but the probability is relatively low.
It is important to note that not all typhoons affecting Jiangsu make "direct landfall" in the province. In fact, many typhoons first make landfall in Zhejiang, Shanghai, Fujian, and other areas, then move northward along Jiangsu's offshore waters or weaken as they penetrate inland, "passing through" Jiangsu and bringing strong winds, heavy rain, and storm surges. A minority of typhoons make direct landfall along the coast of Jiangsu, particularly around Yancheng and Lianyungang. Regardless of the path, both coastal areas and low-lying inland regions must remain vigilant.
Average Number of Typhoons Per Year
According to multi-year statistics from meteorological departments, an average of 2–4 typhoons significantly affect Jiangsu each year, although the specific number fluctuates considerably from year to year. Some years see fewer typhoons, with only one grazing the area; other years may experience consecutive typhoon impacts. For example, in 2018, Typhoon RUMBIA caused severe wind and rain impacts across many parts of Jiangsu.
The impact of typhoons on Jiangsu varies greatly: some bring only showers and short-lived strong winds, while others can cause more serious disasters such as urban waterlogging, flooded farmland, uprooted trees, and seawater intrusion. Therefore, even if a typhoon does not make direct landfall, one should not let their guard down.
