I’ve seen videos of people surfing in the winter and read articles about it, it’s never explained how they are not dying of hypothermia. It just looks like they are wearing a wet suit. I read that it hypothermia starts below 95 F (35 C), I’m unsure how they are able to hit the water without freezing to death.

I am shit at surfing but I tried 16C water with a 4 mm wetsuit. A 4 mm proper wetsuit did warm me like a sleeping bag in spring… but I got very cold feet and hands and my ears were a pain.
This to say, the suits available on the market, can be up to 8 or more millimeters, they are extremely hot. It’s incredible the first time you try them, it’s wet clothing that is hotter when whet than when is dry.
So the answer is, they use the appropriate protection. And they are doing sport. So they heat by moving.
A suit for non-sport need to be a lot thicker. If you remove the activity from the equation you feel the cold way more.
