Guangzhou, formerly known as Canton, is the capital of Guangdong Province and the third most popular metropolitan area for visitors in Mainland China. The city is the economic centre of the Pearl River Delta and it is one of the leading commercial and manufacturing regions in Mainland China. In addition, the China Import and Export Fair, which is also known as the Canton Fair, is held bi-annually in Guangzhou in April and October.
Guangzhou, situated as it is in close proximity to Hong Kong and Macau at the north edge of the Zhujiang River Delta, is considered as the gateway-not only to south China-but to China as a whole. Guangzhou enjoys a pleasant climate all year round, with a mean yearly temperature of around 22.8 centigrade. Influenced by the Asian monsoon, the rainy season is from April to June; and as it is usually oppressively hot from August to September, the best time to visit is usually between Octobers to December.
