The conditions of the state of the sea on the beaches are determined by physical phenomena that depend on local characteristics.

The parameters of sea waves come from the WAM (Wave Model) with 0.25º resolution and LAM (European Shelf Model) with 0.10º resolution  from ECMWF (European Centre for Medium-range Weather Forecasts) and correspond to the prediction of the model grid point closest to the beach considered, providing forecasts of sea waves (significant wave height, swell, direction medium wave, medium wave period, wave, and temperature of sea water), as well as wind and wind direction at the surface, up to 5 days (H +120), updated daily.

The Institute of Meteorology provides these products to support shipping, coastal activities, water sports, activities, recreation and tourism, these can be developed to anywhere near the coast to the needs of the user.
