Not sure, but I think they close down all public beaches at 11pm. Don't think they'll shoo you away, but they have the right to
Police patrol the area to keep it safe. They will be around but won't bother you if you follow the law. There are Police helicopters which monitor up and down the beach, plain clothes detectives, and police on bikes also can be seen. Usually people leave the parks between 10 to 11 PM.
