Meteomed Weather Data


Raw global model data is sourced by MeteoSolutions from the European Center for Medium-Range Weather Forecasts (ECMWF) and the MetOffice, the UK's national weather service. The Met Office weather data for the first two days are subsequently processed on the MeteoSolutions servers, in order to generate an exclusive forecast atmospheric model for Meteomed, based on a WRF-ARW at 4km horizontal resolution. On the data of the WRF-ARW model, a marine forecast model is then elaborated, always at 4km of horizontal resolution, based on the WW3 (WaveWatch3) model of NOAA (National Oceanic and Atmospheric Administration), which allows you to define the interaction of the wave with the coastal orography and the bathymetry of the seabed. Beyond the two-day forecast, atmospheric and marine data from the global model are used European ECMWF at 9km resolution.

The main improvement, in the use of high resolution Meteomed proprietary data in the first two days of the forecast, is evident in the interaction with the bathymetry, the islands and the coasts; the influence of morphology on the marine condition is essential to have reliable information for the harbors and for all areas with complex orography, where the interaction of the wave with the obstacles is decisive.

On our web pages, displays UTC (Universal Time Coordinated) which corresponds to local time solar zero meridian passing through the Greenwich observatory. To obtain the Italian local time in solar time regime (in practice between the last Sunday of October and the last Saturday of the following March) one hour must be added to the UTC time. Instead in daylight saving time (between the last Sunday of March and last Saturday in October) you need to add two hours to UTC time.


The atmospheric and marine data present on the SMS and on the automatic responder are taken from a representative point of an entire sector, more or less vast. In some cases the weather and sea conditions may differ even over a very small area, for a more in-depth analysis we also recommend the use of the cartographic map.

For the first seven days of the forecast (first 168 hours) the data are on an hourly basis, from the eighth to the tenth day they are every 12 hours.
