Simulating WAves Nearshore (SWAN) Regional Wave Model: Palau

Sea State

Simulating WAves Nearshore (SWAN) regional wave model 14-day hourly forecast for the Republic of Palau. The computation utilizes spatial resolution ranging from 3,000 m in the open ocean to 50 m at the shore, with model results interpolated to a 275-m grid for display and archive. This high-resolution model captures key coastal wave processes such as refraction, shoaling, breaking, and shadowing to provide a general indication of the nearshore environment. Boundary conditions are derived from global and regional WaveWatch III models operated by PacIOOS. Global wind forcing and polar ice coverage are provided by NOAA's Global Forecast System (GFS), while astronomical tide levels are defined using the Oregon State University Tidal Prediction Software (OTPS) to modulate wave transmission into reef lagoons. While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, various sources of uncertainty and error remain. As such, please use these data with the appropriate caution, especially for activities involving ocean safety or decision-making.
