High waves that oftenly generated by winds and tropical cyclones, pose a significant threat to Indonesia's coastal regions. While waves pose a risk of coastal hazards, they also hold immense potential for renewable energy source. This study aims to analyse the wave characteristics in the southern Banten waters, particularly in Binuangeun, an area with high wave potential identified in 2020. The analysis focuses on wave spectra, wind sea and swell probabilities, and sea state. A wave model Simulating Wave Nearshore (SWAN) software was utilized to conduct the study with wind data, bathymetry, and open boundary wave data as input parameters. The simulation commenced with a regional domain and then refined its resolution to a local domain using nested and unstructured grids. The model generated data on wind speed and direction, wave height and direction, and wave spectra with spatial and temporal variations. The model results show that wind patterns followed Indonesia's monsoon winds, and wave height patterns exhibited a northward trend, with the maximum height recorded in July, reaching nearly 4 meters. Waves in this region were primarily dominated by swell, with swell occurrence probabilities exceeding 90% every month. The highest energy intensity values were observed for periods exceeding 10 seconds. Sea state characteristics assessed at Pulau Deli indicated that the maximum wave height occurred in July with most frequent wave occurrence probabilities 3 – 3.25 meters and 10 – 10.5 seconds, with the distribution percentages of 10.21%. This study provides valuable insights for wave energy potential utilization in this region.
