Oceanweather provides the coastal and ocean engineering community with definitive metocean design data. Site-specific products are available for the Gulf of Mexico (GOMOS2017), Caribbean, Persian/Arabian Gulf (PERGOS), West Africa (WANE3), US Coasts, and global (GROW2012), as well as daily global wind and wave forecasts.


  • Oceanweather Speculative "Spec" Products
    Spec products are products licensed, administered, and governed by Oceanweather (OWI) and/or a partner in the product. OWI Spec products include the following categories of hindcasts: Advanced Spec, GROW-FINE, and GROW....

  • Advanced Spec - Analyses of all wind fields including intensive tropical cyclone modeling are included on grids similar in resolution to GROW-FINE. These products also include either 2-D or 3-D current modeling.

    GROW-FINE - GROW-FINE hindcasts are generally GROW winds run on a finer resolution wave grid, which resolves the coastline, islands, and bathymetry better than GROW alone. Additional analysis of the winds for the highest rank storms by an expert meteorologist may also be included.

    GROW - GROW is intended as a fast turnaround product for initial estimates of site-specific extremes and operability data for the global oceans. Final design criteria, especially those in tropical basins, are best served by a more intense hindcast approach of the other three categories or a dedicated hindcast.

    GROW Add-on - GROW-MET, GROW-HYDRO, and GROW-TIDE are datasets available for purchase by the point alone or in conjunction with any of OWI's speculative products.

  • Joint Industry Project (JIP)
    Basin-wide studies in frontier areas where participants receive large archives of grid points. Intensive wind analyses are performed for all high-ranked storms and many, if not all, background wind fields are reviewed.


  • Although the upfront costs may be higher, participants typically benefit from ongoing updates, verification against their own measurements, and input into deciding future work performed by Oceanweather or other specialists. Oceanweather has over four decades of experience with JIPs covering essentially every major basin. Some historical JIPs include:

    • BOBUMS
    • BOMOS
    • BORE
    • CREST
    • GLOW
    • GUEST
    • NEXT
    • NUG
    • RASMOS
    • SEAMOS
    • SIMOS
    • SOUP
    • SUS
    • WANE
    • WASP
    • WAX
    • WINX
  • Global Wind and Wave Forecasting
    Since 1983 Oceanweather has applied it's models and analysis techniques for operational forecasting of ocean winds and waves. We are the only forecast center in the world to run operational global and regional wave models developed completely in-house....

  • Our forecast philosophy is to use man-interactive techniques and analysis tools to produce a better marine forecast than is possible using pure model forecast data. Our team of marine meteorologists, most with decades of experience, are dedicated to producing the best wind and wave forecasts.

    Since 1983, Oceanweather has operated a real-time forecasting division. The methodology follows a unique approach of optimally combining traditional weather forecasting (which retains the contributions of individual forecasters) and Oceanweather's high-level technology developed and applied in its hindcasting and consulting divisions. The forecast system includes a global wind and wave forecast system and high resolution regional applications.

    In 1983, Oceanweather (OWI) was approached to produce a wind and wave forecast for the Discoverer Seven Seas which was one of the largest drillships in the world. OWI had already built a reputation for pioneering the hindcast approach in developing metocean criteria for structure design as well as developing new wind, wave and tropical models. The result was the first operational forecast system which computed vessel response, an approach that is being "rediscovered" even today.

    Since then, OWI forecasting has expanded rapidly. In the late 1980's the operational forecast was extended to the North Atlantic and North Pacific. A partnership with Ocean Systems produced the first onboard optimum ship routing system which has continued to evolve into today's Vessel Optimization and Safety System (VOSS). In the 1990's forecasting was extended to global coverage and regional high-resolution nested models began operational use. The first global wave graphics on the Internet appeared in 1994 as Oceanweather unveiled its Current Marine Data web site for the maritime community.
