Hong Kong, located on the southeast coast of China and east of the Pearl River Delta, has developed from a trading port in mid-19th century to a costal cosmopolitan metropolis today. As a highly developed territory, Hong Kong has the most skyscrapers in the world and ranks fourth on both UN Human Development Index and Global Financial Centres Index.
With over 7.5 million residents of various nationalities in a 1,104 m2 territory (only 24% built-up area due to its mountainous topography), Hong Kong is one of the most densely populated places in the world. Most highly-urbanized areas in Kowloon and Hong Kong Island are classified as compact high-rise Local Climate Zone. Hong Kong has a humid subtropical climate influenced by monsoons, particularly characterized with a hot and humid summer, and a cool and dry winter. According to the climate data of Hong Kong Observatory from 1991-2020, the maximum, mean, minimum temperatures are 36.6, 23.5, and 0.0 °C, respectively, and the mean relative humidity is 78%. Therefore, Hong Kong is considered an ideal location to study urban climate due to its unique urban morphology and severe heat stress associated with urban heat and moisture islands in summer.
