Abstract

Ocean waves are one of the important aspects of oceanography in planning coastal structures, determining port layouts, shipping routes, and managing the marine environment. There are many factors that influence ocean waves, one of which is wind speed and direction. Waves can generate energy to shape the beach, create currents, and cause forces that act on coastal structures. Therefore, wave data is needed as a parameter in planning coastal structures. This study aims to determine the wave height and wave period at Pangali-ali Beach, Majene, based on a wind speed distribution model and to compare the wave forecasting results using the SPM (Shore Protection Manual) method with Altimetry Satellite data. The results of this study indicate that the dominant wind direction based on wind data over 10 years (2014-2023) is from the Southeast with an occurrence frequency of 27.2%. The wave height forecast using the SPM method occurred in 2014, measuring 2.63 m with a wave period of 7.25 s.
