It is hard to tell you the exact climate this year, but according to the previous year, the average temperature is about 24C, so you can wear summer clothes.
For the shopping, what kind of products do you want to buy? If you can tell me, maybe I can help you to find some wholesale market for you. Or you can go to the shopping mall such Zhongminbaihuo Shopping Center.
