What's the temperature in Gulangyu Island in Xiamen in October? Can I swim in the water?

If it doesn't rain and there is no typhoon, it's ok, about 27-33 degrees, which is similar to the feeling in summer. Sooner or later, the wind will be stronger and a little cold. It's okay to go swimming in the afternoon, but it won't work if it rains or there is a typhoon. Even if there is a typhoon in Xiamen in August, it is quite cold and there is no way to go swimming, so it is best to look at the weather forecast in advance. Typhoons are usually reported in advance! ~
