How can I keep my hair healthy when I go to the beach?

I'm going to the beach for a week and it'll be really windy, plus all the salt in the air (I'm not going swimming in the ocean, it's a beach in Oregon which is too cold to swim in), so I'm going to need to protect my hair from the salt in the air, and from wind damage. My hair right now is in fairly good shape. I never use any heat on my hair and I use a leave in conditioner. How can I really avoid damage though?
