Discover SeaConditions

SeaConditions is a public service providing weather forecasts at sea. Forecasts concerning the Mediterranean Sea are produced by numerical models using  satellite observations and in situ data (e.g. opportunity ships and buoys).  The computation is based on state-of-the-art ocean models, delivering detailed information with high spatial and temporal resolution. Forecasts for a time-span of 3 four days and a half, with a time resolution of 6 3 hours for the first two days and a half and of 6 hours for the second two, are produced. SeaConditions provides following information: 

  •  "sea-forecasts" that is: sea surface temperature, surface currents, significant wave height and direction, wave period and direction
  •  "air-forecasts" that is: air-temperature at 2 meter a.g.l., surface pressure, precipitation, cloud coverage, 10 meter a.g.l. wind;
  • "sea satellite observations": chlorophyll concentrationwater transparency;
  • sea level;
  • bathimetry and awash rocks. 

The forecasts are displayed as an information layer superimposed on a Google-map. The graphical rendering includes color shading and/or arrows, depending on the field to be displayed. 

All forecast times are UTC-based (Coordinated Universal Time). See table below for some examples: 

The service is available on the web and on mobile (Google Play ed Apple Store)

SeaConditions is a product of the TESSA project, executed by: 

  • Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC) and Istituto per l'Ambiente Marino e Costiero (IAMC-CNR). These project partners are responsible for the research activities and the distribution of ocean model products; 
  • Links s.p.a., which has realized the system for web publication of the forecasts. 

Meteorological forecasts are  produced and certified by the Italian Meteorological Service (

The forecast are produced by the Mediterranean Forecasting System ( of the Italian Institute of Geophysics and Vulcanology (INGV, Bologna, Italy) and delivered through Copernicus/MyOcean ( 

Data source for water level observations and forecasts are provided by Italian Institute for Environment Research and Protection (ISPRA).

Bathymetry and awash rocks data are provided by the Hydrographic Institute of the Italian Navy (IIM). Those data does not replace, nor will replace data provided directly by the IIM or, in general, any other nautic official document.
