Zhuhai (/ˈdʒuːˈhaɪ/, Chinese: 珠海; pinyin: Zhūhǎi; Yale: Jyūhói; literally: "Pearl Sea") is a prefecture-level city on the southern coast of Guangdong province in China. Located in the Pearl River Delta, Zhuhai borders Jiangmen to the northwest, Zhongshan to the north, and Macau to the south. Zhuhai was one of the original Special Economic Zones established in the 1980s. Zhuhai is also one of China's premier tourist destinations, being called the Chinese Riviera. While the city is located in the traditionally Cantonese-speaking region of Guangdong Province, a significant portion of population is now made up of Mandarin speaking economic migrants originally from inland provinces.
The core of Zhuhai in the northeastern portion of the administrative division, is part of the Guangzhou-Shenzhen built-up area on the mouth of the river delta, the biggest built-up area in the world with more than 44,478,513 inhabitants at the 2010 census, encompassing Shenzhen, Dongguan, Foshan, Zhongshan, Macao, main part of Guangzhou, and small parts of Jiangmen and Huizhou cities.
According to a report released in 2014 by the Chinese Academy of Social Sciences, Zhuhai is the most livable city in China.
Zhuhai borders the Macau Special Administrative Region (north and west), and is 140 kilometres (87 miles) southwest of Guangzhou. Its territory includes 146 islands and a coastline of 690 kilometres (429 miles).
The islands within the prefecture-level city of Zhuhai include a number of near-shore islands, often connected to the mainland by bridges or causeways (such as Hengqin, Qi'ao, or Yeli Islands), as well as some islands in the open South China Sea (the Wanshan Archipelago). Some of the latter are actually geographically closer to Hong Kong than to the Zhuhai mainland. The jurisdiction of Nei Lingding Island, located in the Pearl River estuary was transferred from Zhuhai to Shenzhen in 2009.
Zhuhai has a humid subtropical climate affected by the East Asian Monsoon (Koppen classification Cwa) and moderated by the South China Sea, with long, hot and humid summers with frequent thunderstorms, and short, mild and dry winters. Average highs in January and July are 18 and 32 °C (64 and 90 °F) respectively. It never snows and a frost has never been recorded in the city centre. Conversely, extreme heat waves do not occur as they do further inland.
