What wind forecast datasets are available for forcing a wave forecast model? I am trying to set up a spectral wave model for waves forecasting in the Mediterranean. I need the meteorological forecast for this region. I am aware of the ECMWF datasets. But unfortunately, only the reanalyses datasets are freely available. 

So, is there any free source for wind forecasting which covers the Mediterranean region?
Yes, the GFS model is a global model. The data is released in the public domain, so you can use it for free for any lawful purpose. See complete terms of use here. You can get the data here.
