Data from Open-Meteo • Updated 12:26:26 PM
Hong Kong's air quality is affected by local vehicle emissions, shipping in the harbor, and regional pollution from the Pearl River Delta. Winter monsoon winds can bring pollution from the mainland, while summer typhoons clear the air dramatically. The city's extensive trail network in the hills offers escape from urban pollution.
