Beach, anyone? (Jeddah)

I need help, otherwise pretty soon i'm going to a hospital and telling them I suffer from lack of Sun and my skin is turning white.. I look like the girl from Grudge so it scares people.

Ok, let's go back to my question here...How do I get in a mixed beach resort, anyone? FOR ONE DAY?

I don't want to have to make a yearly membership that frankly costs third of my salary. I just want one day where I can get in and out, be fulfilled for the rest of the week that I had one great day at the beach. I've been looking around and no luck!

Are only westerners allowed in? I'm dying to SEA some water here.
