In 2013, the Instituto Español de Oceanografía (IEO) developed a maritime data downstream service (http://playas.ieo.es) particularly focused on providing sea surface temperature (SST) at Iberian Atlantic beaches, a parameter that, although basic for the scientific community, it was certainly rather unusual in those weather forecast reports to the wider public. Thus, although the web-service enhances the visualization of SST at more than one thousand beaches, it also provides 3-day forecast of a set of other meteo-ocean variables (air temperature, wind speed and direction, wave height, period and direction, and tides).
