August is a hot month during the summer season with the average temperatures in a high range of 26.7°C (80.1°F) to 31.1°C (88°F). Many days experience the mercury crossing the 32.2°C (90°F) and a few days hit 35°C (95°F).
Rains are near to their peak with 431.8mm (17") scattered over 17 days in August, as Hong Kong rarely receives a direct hit by cyclones but is often caught in the outer edge of these storms when torrential rain covers the monthly rainfall in a few days.
Summer hosts many festivals, fairs, and events that bring joy to tourists and locals alike. The Golden Bauhinia Square sees the daily flag-raising ceremony irrespective of rain or shine and is a nice place to visit in the backdrop of a world-renowned convention center. Another option is to visit the world-famous Madame Tussaud's Wax Museum with the aid of plenty of refreshing drinks on the way to beat the heat and perspiration.
