Here's how the next 5 days are shaping up at Sebastian Inlet, Florida - East Coast. Each day is rated based on breaking wave height, swell period, and wind — updated hourly from the latest NOAA GFS run.
Thu, Sep 3: 2–3ft, 9s period, rated Poor. Get out early for the best of it — 2-3ft waves on ENE swell at 6s and 7mph ENE winds. Conditions go downhill through the afternoon.
Fri, Sep 4: 2–3ft, 5s period, rated Fair. Early morning is your best window — 2-3ft waves on E swell at 5s with moderate S wind around 8mph. The E wind kicks in by afternoon — 13mph and very poor by then.
Sat, Sep 5: 1–2ft, 4s period, rated Very Poor. Not the most exciting day — 1-2ft and very poor conditions with gentle S breeze. Winds do pick up a bit by the afternoon to 13mph.
Sun, Sep 6: 1–2ft, 7s period, rated Poor - Fair. Get out early for the best of it — 1-2ft waves on E swell at 6s and light WSW winds. Wind fills in through the day, pushing up to 9mph from the E and dropping conditions to poor.
Mon, Sep 7: 1–2ft, 9s period, rated Poor - Fair. Get out early for the best of it — 1-2ft waves on ESE swell at 7s and gentle W breeze. Conditions go downhill through the afternoon.

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 5.5s swell period. Wind is E at 9mph. 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 1.7ft E wind swell swell at 6s, a 1.1ft E secondary swell at 9s, a 0.8ft NNE wind swell swell at 5s. 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 Friday from 6 AM to 9 AM with 2ft waves, a 5.3s swell period, and conditions rated Fair. 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.

The prime season at Sebastian Inlet is fall, when swell direction, wind patterns, and water temps line up most consistently. Outside the peak season you can still score, but you'll need to watch the forecast closely for the right windows.
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. 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).
