30th Street is a beach break in Ocean City offering punchy sandbars shaped by the jetty system that runs along the island. The SE-facing exposure picks up S and SE swells from tropical systems and nor'easters, producing fast, hollow rides during fall hurricane season. Like many OC breaks, the sandbars shift seasonally, rewarding surfers who learn to read the constantly evolving bottom.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at 30th St. is 2-3ft with a 9.35s swell period. Wind is SW at 6mph and conditions are rated Poor - Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at 30th St. is 2-3ft, produced by a 2.2ft ESE primary swell at 10s, a 1.1ft SE secondary swell at 8s, a 0.5ft SSW tertiary swell at 3s. 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.
Based on the current 5-day forecast, the best window to surf 30th St. is Sunday from 6 AM to 9 AM with 2ft waves, a 5.7s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
30th St. works best with a SE swell and NW winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at 30th St.. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.

Common hazards at 30th St. include rip currents, shifting sandbars, crowded lineups during summer, cold water in winter, jellyfish in summer. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our 30th St. 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. See the forecast accuracy card above for per-spot and regional performance metrics.
