The ocean water is also at its warmest, superb for swimming and surfing. All the local shops, restaurants, and attractions are fully operational, offering the complete coastal experience. This is especially true for families looking to enjoy classic beach vacations, with plenty of opportunities for sandcastles, swimming, and boardwalk strolls.For couples seeking a slightly quieter experience with pleasant weather, the shoulder seasons of late May to mid-June and early to mid-September are also excellent choices.
