Jones Beach State Park on Long Island typically follows a schedule that varies between the "Beach" areas and the "Park" as a whole. Generally, the beach and swimming areas are open from Sunrise to Sunset. During the peak summer season (Memorial Day through Labor Day), lifeguards are on duty from 9:00 AM to 5:00 PM on weekdays and 9:00 AM to 7:00 PM on weekends; once the lifeguards go off duty, swimming is strictly prohibited. However, the park itself often stays open until 10:00 PM or Midnight for those using the boardwalk, the "WildPlay" adventure park, or attending concerts at the Northwell Health at Jones Beach Theater. If there is a major concert, the parking lots near the theater remain open until the event concludes. It is important to note that the parking toll booths usually stop charging for entry around 4:00 PM or 5:00 PM depending on the day, but you must still exit the park by the posted closing time. During the winter months, hours are much more restricted, and many of the amenities close early. Always check the official New York State Parks website for "real-time" alerts, especially if there are weather events or special events that might lead to an early closure of the causeways.
