Parking is free after Labor Day! It's nice in September, water still fairly warm, not as crowded but still lots of folks there. My favorite time of the year, actually. No lifeguards on duty, flotation devices allowed so that's nice! Our gang used to all bring floaties to the beach on the first Saturday after Labor Day and act like kids! Pets allowed too. Don't know about services like the guy who rents umbrellas and chairs, so plan to bring them.
