The air isn't that bad, I live down here and am always shooting in it. If there is salty air, I don't know about it. It can become humid at the beach so watch out for fog on your lens. It's sometimes known to happen in the morning and evenings. Don't exchange lenses in the open beach area. Go to your car for that, and trust me you want to try different angles while your down here. Don't get the camera wet. I know it's obvious, but I thought a reminder wouldn't hurt.
I included a link of some pictures I took about a week ago of famous attractions in Corpus Christi that I thought you might want to go see or take pictures of:
