Despite Hong Kong's reputation of being intensely urbanised, the territory has tried to promote a green environment, and recent growing public concern has prompted the severe restriction of further land reclamation from Victoria Harbour. Awareness of the environment is growing as Hong Kong suffers from increasing pollution compounded by its geography and tall buildings. Approximately 80% of the city's smog originates from other parts of the Pearl River Delta.
Though it is situated just south of the Tropic of Cancer, Hong Kong has a humid subtropical climate (Köppen Cwa). Summer is hot and humid with occasional showers and thunderstorms, and warm air coming from the southwest. Summer is when typhoons are most likely, sometimes resulting in flooding or landslides. Winters are mild and usually start sunny, becoming cloudier towards February; the occasional cold front brings strong, cooling winds from the north. The most temperate seasons are spring, which can be changeable, and autumn, which is generally sunny and dry. Hong Kong averages 1,948 hours of sunshine per year, while the highest and lowest ever recorded temperatures at the Hong Kong Observatory are 36.1 °C (97.0 °F) and 0.0 °C (32.0 °F), respectively.
