hello! may i know the weather in Hong Kong on late August till early September 2013?

Hi, it will be hot and humid. The average temperature is around 29C. So summer clothes are needed to be taken along. At the same time, it may rain frequently and the thunderstorms or typhoons may block your trip sometimes. Therefore, umbrella and rainy coat are also needed to be prepared.
In general, I suggest you pay attention to the weather forecast before going out.
