Sebastian Inlet is the most famous surf spot in Florida, where offset jetties create a sand-bottom wedge producing performance-quality rights off the north jetty. First Peak — immediately adjacent to the jetty — was one of the best waves on the entire East Coast for nearly 40 years (diminished after a 2003 jetty retrofit). Monster Hole on the south side's ebb shoal provides rides up to 400 yards on epic swells. Alumni include Kelly Slater, Lisa Andersen, and the Hobgood twins. State park entry fee required.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Sebastian Inlet is 1-2ft with a 8.6s swell period. Wind is ENE at 13mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Sebastian Inlet is 1-2ft, produced by a 1.2ft ENE primary swell at 9s, a 0.8ft ESE secondary swell at 4s, a 0.2ft E tertiary swell at 13s. 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 Sebastian Inlet is Thursday from 6 AM to 9 AM with 3ft waves, a 7.85s swell period, and conditions rated Fair - Good. Check the hourly forecast for updates as conditions can shift.
Sebastian Inlet works best with a NE swell and W 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 Sebastian Inlet. 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 Sebastian Inlet include strong currents, rip currents, jetty rocks, boat traffic, sharks, localism, crowded lineups. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Sebastian Inlet 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.
