what kind of temperature and weather di I expect in last week of august?

It is still the hot summer days at the end of August in Beijing. The temperature may varies from 22~30C. It may rain often at that time. You need to prepare light clothes as short-sleeved T-shirts and shorts. Remember to pack a raincoat or umbrella just in case.

pleasant temperature just under 30C, but getting quite cold in night and early morning for sweater, during daytime it's fine for (t-)shirt, not so rainy as was beginning of august, folding umbrella anywhere on street cost 10RMB if you will be left without umbrella
