Wearing shorts and tank tops in Guangzhou?

I’m afraid you cannot only take the tank tops and shorts with you, because it will be rainy season in Zhanjiang City and may rain lasting over one month according to the current weather forecast. But the temperature will be about 25C - 35 C on average. You’d better take some coats and an umbrella. At the same time, you also need sunblock to protect yourself from the sunburn.
