Will it be cold to drift at 23 degrees?

No, it is cold. Drifting is an adventure and entertainment activity. When the water temperature is too low at 23 degrees, people will feel cold, causing muscle contraction and nervous tension, so drifting at 23 degrees will lead to colds or fever. It usually takes about 30 degrees to raise the water temperature to a comfortable temperature, and 23 degrees is not enough to heat the water temperature, so it is very cold.
