Abstract
Aims: To determine the distribution of maximum average wave height in the southern waters of Java Island and to identify the time and season when the maximum average wave height occurs.
Study Design: Analyzing the map of the distribution of maximum average wave height in the southern waters of Java Island.
Location and Duration: Department of Physics, Udayana University, and Indonesian Agency of Meteorology, Climatology, and Geophysics (BMKG) TunggulWulung Meteorology Station Cilacap, between January 2023 and February 2023.
Methodology: Daily maximum wave height data in the southern waters of Java Island from January 2010 to December 2021 at 00.00, 06.00, 12.00, and 18.00 UTC, with a latitude coordinate limit of 7°S to 12°S and longitude of 106°E to 112°E. The data was calculated using Microsoft Excel and grouped by season and time. The maximum average wave height data was then plotted using Surfer software, and the result is a map of the distribution of maximum average wave height.
Results: The highest maximum wave height was found in the South Indian Ocean from West Java to East Java. The highest maximum wave height in the southern waters of Sukabumi-Garut West Java, and the lowest in the southernwaters of Pangandaran-Yogyakarta. The maximum average wave height tends to be high in the morning at 18.00 UTC for the Transition I, East Wind, and Transition IIseasons. Meanwhile, during the WestWind season, the maximum wave height tends to be high at 12.00 UTC. The highest maximum average wave height occurred during the EastWind season.
Conclusion: The map of the distribution of maximum average wave height can be used as a consideration for predicting the maximum wave height in the southern waters of Java Island.
Keywords: West wind season, maximum wave height, surfer, southern waters of Java Island, east wind season
