Shanghai's Climate
Shanghai has a humid subtropical climate with four distinct seasons and high humidity year-round, owing to its coastal setting at the mouth of the Yangtze. Winter (December to February) is cold and damp, occasionally biting but rarely snowy, while summer (June to August) is hot and sticky. Early summer brings the prolonged Meiyu (plum rains), and late summer into early autumn is when typhoons and tropical systems can make landfall.
