Diamond Beach is a quiet stretch of Atlantic-facing shoreline near the southern tip of Cape May County, offering mellow waves ideal for beginners. The SE-facing coast picks up swells that wrap around the Cape May Peninsula from tropical systems and southerly storms, producing smaller, more manageable surf than the more exposed beaches further north. Light crowds and a relaxed atmosphere make it a peaceful option for surfers seeking uncrowded New Jersey lineups.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
