How cold is too cold for surfing

It is never too cold.

Just make sure that you have a good wet suit.

And something warm in the car/van for after.

Got some great waves at Gwithian on Boxing day a few years ago. That was with a 3mm summer suit!!!

Had to come out after an hour!! Cleared the head though.

Depends on what your wearing.

Dry suit -- Atlantic in winter
Wet suit -- 60f
No suite -- 70f ;)

When you can do nothing but ice-skate on the water.

Given a good wet suit and the ability to tolerate cold, it is never too cold. People have surfed above the Arctic circle and at Antarctica. RipCurl developed a new heated wet suit this year that may open up a whole new realm of possibilities of surf spots.

For me, l will surf if the water is above 45F but only if it is a nice day. No duck diving during nor'easters thank you very much.

it is never too cold, but l only surf cold water like once a year, l live where da water is warm and waves all year long

when you get out and cant get the key in the keyhole of your cars door because of shivering too much, had that a few times.

NEVER!!!! wear a dry suit.
