Is it cold in Qinhuangdao in early September?

I went there at the beginning of September last year. I didn't go into the water. I felt scared and a little cold.

At the beginning of September, the weather will gradually turn colder. It is still relatively cold in the morning and evening. It is recommended to wear long sleeves to go out, and it is better not to go to the sea in the morning and evening. It is relatively reluctant when the sun is the hottest at noon. It is only about 25 degrees. It depends on you. Physical fitness, the picture is the weather data in September last year, you can refer to it. <br/><br/>Come in early September, the sea is open, and seafood will be more delicious than it is now. <br/><br/>Please click the green "Accept as best answer", thanks
