I've surfed for 8 or nine years (yeah, I live in Sacramento now, but I refuse to sayt I've given it up, I'll be back eventually.)
Learning is a very trying experience. It'll be easier down south, where the water's warmer. Up in Santa Cruz, it takes quite a bit of dedication jsut to keep getting in the 55 degree water. It takes a long time to learn, years to get good, and decades to master. It's not like learning to ride a bike or play basketball, it's much, much more difficult. The hardest part is that you can't do it at your leisure. If you're trying to improve your 3 point shot, you can jsut keep grabbing the ball and shooting until you've practiced as much as you like. With surfing, Postitioning yourself so that you can actually get waves is as important as actually standing up and riding the wave. If you can't get waves, you can't learn. And if you go to any of the better spots, there are guys who have surfed there every day for years, and they're not likely to be passing on any decent waves so that some kook can try his hand at learning to stand up. So, if you want to learn, definitely find a beginner friendly beach (NOT places like windansea, silver strand, pleasure point, steamer lane... and those are jsut a few of the places not to go in CA). If you were in Santa Cruz, I'd suggest Cowell's Beach, but I don't know any beginner places down south. Get a longboard, they're a LOT easier to paddle and balance on. Once you get the hang of that, you can try a shortboard if you're into tricks and stuff. I qouldn't recommend a bodyboard. They're not as fun, and, at lest up here, you command absolutely no respect on one. The general rule is that the first person to catch the wave, or the farthest person back, gets the wave. No one counts bodyboarders as surfers though, and almsot anyone will drop in in front of them. The attitude is basically "if they want respect, they can learn to stand up like everyone else did". (also - what are you more likely to aviod, a 2 foot sponge, or a 6 foot pointed fiberglass dart with 6" fins sticking out of it?).
Oh, and after I moved up here, my brother decided my brand new, custom shaped, $400 board was available, since I wasn't using it, and he snapped it. There are few things that piss you off more than a snapped board. I once snapped a $500 longboard on the first day of a 3 day trip, and it was the only board I brought. That blew.
