Dewey Beach, Delaware, is a public beach and is technically "open" 24 hours a day for walking and enjoying the view. However, in 2026, the specific "operational" hours for the beach are governed by local ordinances and safety regulations. Lifeguards from the Dewey Beach Patrol are typically on duty from 10:00 AM to 5:00 PM during the summer season (Memorial Day through Labor Day). Swimming is strongly discouraged when lifeguards are not present. Regarding parking, meters are in effect from 10:00 AM to 2:00 AM daily, though there are "free parking" windows on Monday, Tuesday, and Wednesday evenings after 5:00 PM. For those interested in the famous nightlife, the town’s bars and restaurants usually open for lunch around 11:00 AM and remain active until the mandatory 1:00 AM or 2:00 AM closing times. If you are looking to secure a prime spot on the sand, there is no official "opening" gate, but most families begin to arrive around 9:00 AM to beat the midday heat and the rush for parking spots.
