Ah, the west coast water is fine if you know what to expect. I do enjoy the ocean off Florida when I'm out there, but I've also been there in the dead of summer and gotten soaked moving between buildings without a drop of rain falling! I also vividly remember using my windshield wipers to scrape off the love bugs while I was driving to the Cape at the end of September.
That said, when I was living in Denver I had co-workers who had just moved from Florida. They couldn't take the dry air and moved back without jobs! It's all a matter of what you're used to.
