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).

The tidal gauge of Algeciras was located at the harbour and it measured sea level from 1943 to 2002. A new tide gauge (PSMSL ID 2117) replaced this stations with records from 2006 onwards.

The tide gauge of Tarifa is located in the harbour and it measures the sea level from 1943 onwards.

The tide gauge of Pasajes measured the sea level from 1948 to 1963.

The tide gauge of Palma de Mallorca is located in the eastern part of the harbour and it measures the sea level from 1964 to 1966. Note that another station (PSMSL ID 1892) was recording data from 1997 onwards in a near location.

The tide gauge of Vigo is currently located at the fisheries harbour and measures the sea level from 1943 onwards.

This oceano-meteorological buoy was deployed on September 27, 2007, at the position 43º50'N 3º47'W, located 22 miles North of Cabo Mayor in Santander. Water depth at the buoy is 2850 meters. Parameters: - Sea water temperature at 3 m depth - Sea water slinity at 3 m depth - Air temperature - Relative humidity - Atmospheric pressure - Wind speed and direction - Waves (significant wave height, height, period and direction) - Currents at 9 m depth - Chlorophyll-a - Oxygen

Salinity monthly climatology for the Iberian Peninsula region, Balearic Islands and Canary Islands, at 0.2º of horizontal spatial resolution and 33 vertical levels.

The tidal gauge of Málaga is located at the harbour and it measures sea level from 1943 onwards, with a gap between 1959 and 1961.

The tide gauge of Puerto de la Luz (Las Palmas de Gran Canaria) is located at the reina Sofía dock and it records sea level data from 1949 onwards.
