Rehoboth Beach, Delaware, is technically open to the public 24 hours a day, but specific activities are governed by strict 2026 ordinances. The beach is accessible for walking at any time, but swimming is only permitted when lifeguards are on duty, typically from 9:00 AM to 5:00 PM during the summer season (Memorial Day through Labor Day). The famous Rehoboth Beach Boardwalk also remains open around the clock, though most shops and amusements close by 11:00 PM or midnight. It is important to note that "sleeping or loitering" on the beach is prohibited between 1:00 AM and 5:00 AM to allow for cleaning crews to maintain the sand. If you are driving, parking meters are in effect from May 15th to September 15th, usually from 10:00 AM to 10:00 PM. In 2026, the city has also implemented stricter "quiet hours" for the residential areas surrounding the beach, beginning at 11:00 PM.
