A welcoming spot for beginners and intermediates, with a relaxed barrier island vibe that makes it one of the more laid-back stretches of the New Jersey coast.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Sea Isle City is 2-3ft with a 5.9s swell period. Wind is WSW at 8mph. Conditions are rated Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Sea Isle City is 2-3ft, produced by a 2ft E wind swell swell at 6s, a 1.6ft SE secondary swell at 9s, a 1ft SW wind swell swell at 2s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.

Our Sea Isle City forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable; extended forecasts show general trends. We also verify our offshore swell predictions against NOAA buoy measurements daily — see our accuracy page for those swell-verification metrics (buoys measure open-water swell, not breaking surf size).
