See what weather to expect in Hong Kong, China and plan your trip with confidence. Monthly averages from real historical weather data.
Hong Kong's climate swings hard between a drenched, steamy stretch and a genuinely pleasant cool season — making timing your visit more consequential here than in most cities. Rainfall in August can reach 410mm, turning streets into rivers and making even a dash between indoor shopping malls an ordeal. The flip side is a dry, comfortable cool season that lets you roam the city's layered hillside neighbourhoods and harbour-front promenades without breaking a sweat.
