The average and extreme wave climate at north of the Gulf of Urabá was evaluated and determined from 11 years of synthetic wave serie derived from the global model surf WaveWatch III, in order to evaluate different oceanographic scenarios. The series of wave height (Hs) was adjusted to different probability distribution functions (minimum of Weibull, Normal, Log - Normal, maximum of Gumbel), finding that the minimum of Weibull had better fit; the same happened for the number of peak wave period (Tp). Waves heights were found from 1.13 and 2.5 m, wich correspond to probability of on exceedance of 50% and 95% respectively. The waves series of 11 years was fixed to the maximun of Gumble function to define extremal regimes and a wave height value of 4.9 m was obtained for return period of 100 years. These results are relevant to the subsequent analysis of the morphological evolution of the Gulf of Urabá, as well as for the design, functionality and stability of engineering works on the waterfront
