About MetOcean Studies Research
Forecasting Current Marine Data Software

Oceanweather Inc. is a specialized metocean consulting firm serving the coastal and ocean engineering communities since 1977. Our approach is to develop and apply high-level technology to satisfy practical requirements in marine meteorology, ocean wave and current specification, ocean engineering, and statistics of environmental data. Our services include atmospheric/oceanographic research, site-specific consulting/modeling, operational forecasting, and generation of long-term climatologies for operability and design in the marine environment.

  • Eastern Pacific GROW-FINE Hindcast: GF-NEPAC

    Announcing GROW-FINE NEPAC (GF-NEPAC) our latest publically available hindcast for the Pacific coastlines of North and Central America, encompassing Alaska’s Aleutian Islands in the North to the middle of Ecuador’s mainland coastline in the South. This hindcast was designed to be an improvement over other available coastal Pacific wind and wave datasets including ERA5 and our earlier NEPAC products.

    These hindcast data consist of continuous hourly time steps of wind and wave parameters from 1979 through 2021, with 2022 to be added soon. Full 2D frequency-directional wave spectra are also available at a subset of the 0.1° (6-minute) resolution coastal grid, while bulk wind and wave parameters have been archived at each grid point. This archive grid extends from the coastline out into deep water incorporating (at least) the offshore 1000 m depth contour. These data are suitable for a variety of uses in the metocean and offshore design fields, and are available for purchase by point or as a whole and in a variety of formats including statistical analyses.

  • Hurricane Ian Fast Response Hindcast

    In order to support hurricane recovery activities and to improve future resiliency, Oceanweather (OWI) routinely produces “fast-response” tropical cyclone hindcasts for significant storms and has started work on the extremely destructive 2022 hurricane Ian. A detailed reanalysis of the conditions experienced in a land-falling hurricane are required in any ocean response modeling to provide critical guidance on the extent of the storm wave and surge inundation. OWI can provide wind, pressure, and/or OWI’s standard wave fields for these events.

    As experts in providing meteorological forcing for ocean response modeling of extreme wind, wave and storm surge events, OWI has a long history of quickly responding to the need for hindcasts of recent or active tropical events. This expertise is also applied in long-term operational and storm hindcasts in public and private sectors around the globe.
