What's the temperature on the quantum cruise ship?

It is said to be 25-26 degrees, but according to my own feeling, it should be above 20 degrees, but less than 25 degrees. I went on1end of October 165438+. It's not cold in a single shirt boat, and it's not hot in autumn clothes. It is normal cold weather on the outer deck of the ship, and the sea breeze is very strong. I basically don't want to go out.
