Wave Information Study


Update: The WIS Portal has been updated.

  • Dynamic generation of Extremes tables/plots (~8 mins) and Mean-max tables (~5 mins) has been enabled.
  • Download 'fetch' problem has been mostly addressed. Let us know if you encounter issues.
  • The 2021 Hindcast is being rolled out by regions. Alaska, Gulf of Mexico, and the Great Lakes have been updated.
  • We are investigating an issue with Wind/Wave percent occurrence tables for some stations.
  • WIS Project Mission

    The Wave Information Study project provides a national resource of long-term wave climatologies for all U.S. coastal waters using high-resolution wind fields, mean daily ice concentration fields (where appropriate), third generation phase average wave modeling technologies, that are extensively evaluated to point-source measurements and satellite-based altimetry providing high quality wave estimates. The multi-decade hindcasts and storm event archives are generated to meet tomorrow's coastal engineering needs today.


    • Knowledge of the wave climatology is required for planning, design, construction, and maintenance of USACE projects in the coastal zone
    • Information is scarce due to the lack of measurements at locations over timescales long enough to be statistically significant
    • This lack of information is a critical problem for USACE operations, and project maintenance near the coast


    • Generation of long-term coastal wave estimates using spectral wave models forced by high quality wind fields, to retain continuity
    • Validate the model estimates to measurements
    • Provide easy access to the estimates and tailored products specific to project needs


    • Fully automated hindcast system with limited manual intervention
    • Model simulations cost-effective compared measurements
    • Timely web site updates with new wave estimates
