The ensemble numerical prediction of ocean waves is considered and all published works on this new topic in Geosciences are reviewed. A Wave Ensemble Prediction System is described where a global third-generation wave model is adopted. Twenty members are generated by a method based on Empirical Orthogonal Functions and a particular realistic case where several extreme wave events occurred is analysed.
