OWI are pleased to announce the availability of West Africa Normals and Extremes (WANE4), our latest publicly available hindcast for the West African coastline. This hindcast was designed to be an improvement over other available wind and wave datasets including ERA5 and our own previous WANE products.

These hindcast data consist of continuous hourly time steps of wind and wave parameters from 1979 through 2024, with yearly future updates. Full 2D frequency-directional wave spectra are also available along the entire coastline at a subset of archive locations. 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.

WANE4 output data are available on archive grids matching the previous WANE3 hindcast which follow the West African coastline (blue and red computational domains shown).
