Dongguan, a major manufacturing city in the Pearl River Delta of Guangdong province, sits in southern China between Guangzhou and Shenzhen at approximately 23.02°N, 113.75°E. Just north of the Tropic of Cancer, it has a humid subtropical climate (Köppen Cfa) verging on tropical — with long, hot, wet summers and short, mild, drier winters — shaped by the monsoon and exposed to typhoons off the South China Sea.
Summer is long, hot and humid, running from around April to October, with July the warmest month — average highs around 33°C — and oppressive humidity. This is the wet season, when the monsoon brings frequent heavy showers and thunderstorms, and from June to October typhoons off the South China Sea can bring torrential rain, flooding and strong winds to the delta.
Winter, from December to February, is short, mild and drier, with January the coolest month — average highs around 18–19°C and lows near 10–11°C, rarely approaching frost. Cold snaps from the north can briefly bring chilly, damp weather, but genuine cold is unknown. This mild, comparatively dry stretch is the most comfortable time of year.
Dongguan is wet, receiving around 1,700–1,800 mm of rain a year, overwhelmingly concentrated in the wet season from April to September, when monsoon downpours and typhoons deliver the heaviest falls, while winter is relatively dry. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Dongguan shares the humid, subtropical climate of the densely urbanised Pearl River Delta — long hot wet summers and short mild winters — with the delta's dense concentration of cities and industry adding an urban heat-island effect. The typhoon season from June to October is the main hazard, capable of bringing torrential rain and flooding to the low-lying, heavily built-up delta.
