Despite my screen name, I'm not a big fan of cold water and as this has been a recurring topic for spring visitors I thought I'd give an update. IMHO, the gulf is definitely warm enough for frolicking in. As we walked along the beach and I got splashed, my first reaction was OH! Then within a couple seconds it felt fine. NOT like Lake Michigan Fine and you get-numb-so-you-can't-feel-it, but the Hey,-this-feels-pretty-good kind of fine. Family was even swimming in it, but I prefer pools. Remember, water temps in much deeper water are colder, and lately we're getting south winds which bring the top surface water in.
But as always, watch the flags. Earlier we had two days of extremely rough water, so bad that NO-ONE, not even the idiots went in.
