Shanghai enjoys a northern subtropical maritime monsoon climate, characterized by plenty of rainfall and adequate sunshine. Shanghai weather is generally mild and moist, with four distinctive seasons. It has a short spring and autumn and a long summer and winter. The main climate features are: warm in spring, hot in summer, cool in autumn and cold in winter.
The “urban heat island effect” (where an urban area is significantly warmer than its surrounding rural areas due to human activities) is significant in Shanghai with the busy population spread over the vast urban area. The alternation of winter and summer monsoons have shaped the local precipitation. There are three raining period, the spring, the early summer( Meiyu Period), and early autumn. In addition, there are three dry period in the middle and late summer, the late autumn and the winter.
The coldest weather lasts from late January to early February. Although the harsh days are limited, the humid cold and the north wind are tortuous. Please note the wet Meiyu Period between mid-June and early July. During these 20 days, the rainfall is often as much as 25% of the city's annual total. Typhoons frequently visit Shanghai between late August and early September and bring heavy rains.
Weather: The season when flowers bloom, between March and May, is the best tourist season. The average temperature varies between 2 and 9°C, but the weather is fickle.
