I agree, with PP. It's been pretty warm still down here during the day. Even if you're by the ocean you'll still probably want short sleeves during the day and maybe a sweater/sweatshirt at night. Of course, the weather could change all of a sudden and be cold during the day but I would bring a variety of things. You could probably leave the shorts at home if you want to have one less thing to pack, and just do pants and short sleeves unless you think you will get hot easily.
