This paper analyses different wave height concepts used in the literature and discusses some common problems associated with the determination of design wave heights, such as selection of parametric models and estimation. The authors analyze common methods (peak values, peaks over a threshold, yearly maximum, etc) used in fitting wave data and point out the problems associated with some of the commonly used distributions. The use of significant wave heights for design values is analyzed and discussed. It is shown that significant wave heights have practically no individual information about the tail behaviour of wave heights and individual wave heights are proposed as an alternative. The use of the generalized Pareto distribution for fitting wave height exceedances over high thresholds is proposed and justified and an estimation method is given. Finally, the Kodiak data set is used as an example to illustrate the methodology.
