Climate in Shanghai

Under the Köppen climate classification system, Singapore has a tropical rainforest climate with no distinctive seasons. Its climate is characterized by uniform temperature and pressure, high humidity, and abundant rainfall. Temperatures range from 22 °C to 34 °C (72° to 93 °F). On average, the relative humidity is around 90% in the morning and 60% in the afternoon. The lowest and highest temperatures recorded in its maritime history are 19.4 °C (66.9 °F) and 35.8 °C (96.4 °F) respectively.

May and June are the hottest months, while November and December make up the wetter monsoon season. From August to October, there is often haze, sometimes severe enough to prompt public health warnings, due to bush fires in neighbouring Indonesia.

Singapore does not observe daylight saving time or a summer time zone change. The length of the day is nearly constant year round due to the country's location near the equator.

The importance of Shanghai grew radically in the 19th century, as the city's strategic position at the mouth of the Yangtze River made it an ideal location for trade with the West. During the First Opium War (1839–1842), British forces temporarily held Shanghai. The war ended with the 1842 Treaty of Nanjing, opened the treaty ports, Shanghai included, for international trade. The Treaty of the Bogue signed in 1843, and the Sino-American Treaty of Wangsia signed in 1844 together allowed foreign nations to visit and trade on Chinese soil, the start of the foreign concessions.

The geography of Shanghai is characterised by its location on the Yangtze River Delta on China's east coast and its proximity to the Pacific Ocean via the East China Sea. The city is centred around the Huangpu River, a tributary of the Yangtze River, and extends outwards in all directions, with the suburbs and satellite towns reaching east to the East China Sea, north and west to Jiangsu province, and south to Zhejiang province over Hangzhou Bay.

The vast majority of Shanghai's land area is flat, apart from a few hills in the southwest corner, due to its location on the alluvial plain of the Yangtze's river delta. The city has many rivers and lakes and is known for its rich water resources, and thanks to its coastal, riverside location and warm climate ensuring ice-free waters, provides easy access to China's interior, resulting in Shanghai being the world's largest port.
