Wheather in Beijing

Generally it is very hot with abundant rainfall in August of Beijing. The average temperature could be about 26 C or a little higher. In the afternoon or some sunny days, the short or heavy rainstorms may happen suddenly. Therefore, except the short-sleeved shirt and pants, you'd better take along the raincoat or an umbrella. Anyway, the rainfall of Beijing is very dense over the recent days so that whether the rain or floods happen then is still unknown.
As a whole, you need pay much attention to the weather forecast then.
