Water in SoCal is much colder than the east coast. It was 72 today. I wore a full wet suit. Let’s me stay in the water much longer. My husband didn’t bother putting a wet suit on. But I’m a wimp. When I’m snorkeling in Hawaii I wear a full wet suit. I can snorkel for over an hour with the wetsuit on. I”m going to have to do knee repairs on my wetsuit after the season is over.
