July is the hottest month of the year with the average high temperatures at a blistering 31.7°C (89.1°F). It is a time to avoid Hong Kong with its sweltering heat and humidity, as the temperatures rarely drop below the average low of 26.7°C (80.1°F).
Rain is unrelenting with 381mm (15") in the space of 18 days, even though the daily sunshine is at the highest of the year at 7 hours.
For ocean lovers, July is a great time to hit the beach; for swimmers - this is the best time with average sea temperatures of 25.6°C (78.1°F) to enjoy the waters.
Beware of summer thunderstorms and the ultraviolet index of the sun at a dangerous 11, while on a visit to a beach such as the Mui Wo and Silver Mine Bay Beach to escape from the heat and the urban jungle. The longest stretch of sand to beat the summer blues is on Cheung Sha Beach and Pui O Beach.
