Main Beach at Fernandina is Amelia Island's primary surf spot, known for spitting sand-bottom barrels just yards from shore. With limited interference from outside sandbars, it delivers a legit shorebreak experience at higher tides — hollow, fast, and powerful. When a solid NE swell hits in winter, this spot fires with some of the longest, most powerful lines on the island.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Main Beach is 1-2ft with a 6.75s swell period. Wind is ENE at 8mph 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 Main Beach is 1-2ft, produced by a 0.9ft ESE primary swell at 7s, a 0.7ft ESE secondary swell at 9s, a 2ft E wind swell swell at 6s. 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 Main Beach is Monday from 6 AM to 9 AM with 2ft waves, a 4.85s swell period, and conditions rated Poor. Check the hourly forecast for updates as conditions can shift.
Main Beach 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 Main Beach. 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.

Our Main Beach 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.
