The current temp is around 70, so not too bad.

Not too bad for wading in at the beach and paddling around for a few
minutes in calm, controlled conditions. When you're literally
fighting for your life in rough windy conditions after a surprise
immersion, that's an entirely different thing. Have you ever taken a
knock down in a sail boat? Things happen pretty quickly and you get
bumped around quite a bit.
