description Wave power is one of the key sources of generating renewable energy, and it has been widely utilized along the coastal boundary of the whole world. Therefore, it is essential to investigate the global mean and extreme wave power/energy during all four seasons. In this analysis, daily reanalysis data (ERA5) has been utilized for 72 year period from 1950 to 2021. The generalized extreme value distribution (GEV) is ued to determine the extreme values of wave power over the global scale. Further, maximum wave power is evident over the central north Pacific Ocean (PO) and north Atlantic Ocean (AO) during December-January (DJF), while it has been shifted toward the western north PO during June-August (JJA) season. The Southern Ocean experienced a strong amplitude of wave power throughout all seasons. Further, the mean and extreme patterns of wave power are strongly correlated. The rate of increase of wave energy over the global Ocean, Indo-pacific, and SO ranges from 0.11 kW/m to 0.42 kW/m during 1950-2021; however, a significant rate of increase is observed over southern IO during the JJA season. The appropriate locations can be identified for renewable wave energy generation based on global reanalysis.
