Is the temperature in Beidaihe 19-23 degrees suitable for going to sea? I have booked a ticket for July 13. Do you want to return it and go another day?

I have worked at the seaside for a long time, and I also like swimming in the sea. My experience is that 19-23 degrees is too cold to go out to sea. When the temperature is above 30 degrees, the water temperature is more comfortable than 28 degrees (now you can check the sea water temperature, not the weather forecast, but the ocean forecast).

Swimming in the sea when the water temperature is too low is not only uncomfortable, but also prone to leg cramps and so on. Be sure to get ready for exercise and exercise your body, especially your calves and toes.

In fact, it is the coolest after swimming out of the water. Prepare a big towel and wrap it as soon as it comes out of the water.
