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 refer to a time-span of four and a half days, with a time schedule of 3 hours for the first two and a half days and of 6 hours for the second two. SeaConditions provides the following information: 

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

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 information 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 and  Apple Store)

SeaConditions is a product of the TESSA project, created 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 created the system for web publication of the forecasts.

Weather forecasts are based on observations and forecasts produced and certified by the Meteorological Service of the Italian Air Force (

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