There are umbrellas available to rent on the beach. They are rented by the lifeguards on the public beach. I don't remember the cost, but they may be reserved by the day or week.
The beach is wonderful. It is a wide, white sand beach with a very gradual drop, so at low tide you can wade out quite a ways without any undertow to worry about.
Even at high tide, the beach offers plenty of room to lay out a towel or enjoy an umbrella or cabana.
Hopefully someone else can remember the cost.
Enjoy!
