October brings the pleasant autumn season with the retreat of the rain, drop in humidity and cooler temperatures. The summer heat subsides as the temperatures see a gradual decline to average 23.3°C (73.9°F) to 30°C (86°F).
The mostly cloudless skies bring much-wanted dryness after the summer rains and thunderstorms. The risk of cyclones is almost non-existent, which means it is the best time to visit Hong Kong with comfortable conditions on the horizon.
Fall offers an escape from the rainy summer with many options - Dragon's Back is one such option, which is renowned among urban hikers to provide picturesque views of southern Hong Kong with its amazing shorelines during the colorful fall weather. Steer clear from the first week of October as the National Day drives many mainland Chinese tourists to Hong Kong and the place gets crowded.
