Wind-generated surface gravity wave heights and periods are non-observable variables. Notwithstanding, their role in sea environment characterization and consequently in ocean and coastal engineering design criteria is crucial. A new criterion of defining discrete waves from sea surface elevation time series, called orbital criterion, is applied to wave rider buoys records measured off the west coast of Portugal. The method uses the Hilbert Transform and the representation of the time series in the complex plane. Statistics and distributions of wave heights estimated with z-u-c and orbital criteria are employed in assessing the influence of the discretization criteria on the statistical characterization of random waves.
