    • Simulating WAves Nearshore (SWAN) Regional Wave Model: Tutuila, American Samoa

    Metadata Updated: January 27, 2025

    Simulating WAves Nearshore (SWAN) regional wave model 7-day output with a 5-day hourly forecast for the island of Tutuila, American Samoa at approximately 250-m resolution. This high-resolution model is utilized to capture shallow water effects and nearshore coastal dynamics such as refracting, shoaling, and smaller scale shadowing. It is run directly after the Samoa regional WaveWatch III (WW3) wave model (ww3_samoa) has completed. Please note that some of the nested model setup is still in the testing and validation phase. While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, numerous sources of error are possible. As such, please use these data with the caution appropriate for any ocean related activity.
