Our Robert Moses State Park 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).
