Dongguan lies in China’s southern subtropical monsoon belt, where warm, moist air keeps the wet season running from April through September and puts the coast directly in the path of typhoons crossing the South China Sea between June and October.
Sitting within the Pearl River Delta between Guangzhou and Shenzhen, the city’s dense network of canals and rivers can back up quickly when a strong storm cell stalls overhead. A typhoon’s track and intensity can shift within hours of landfall, so live radar imagery is a key complement to official typhoon warnings for tracking rain bands as they move inland. The China Meteorological Administration operates the national radar network covering Guangdong. Learn more: Hurricane Season Radar Guide · Open the full Rain Map
