What it's all about

It's about the belief that quality weather resources should be free and open for the sailing community. It's also about the fact that free download of high resolution output from regional forecast models is not easily available. 

Free and open download of high resolution GRIB files from regional models, is available on this site provided that the use is not commercial. The entire Mediterranean is covered with OpenSkiron and OpenWRF Gribs.

It is possible to view the GRIB files in zyGrib (v6.24 and up), the GRIB plugin for OpenCPN, uGrib and ViewFax.

The site is expanding to include examples on GRIB file usage including Weather Routing. Focus will be on supporting open source tools and free and open weather resources.

  • Greetings to the team at zyGrib for rapidly adapting zyGrib to visualize the Skiron based Grib files available here. zyGrib is undoubtedly among the better Grib readers available and it is free & open source. The newest version of zyGrib is available at http://www.zygrib.org/.
  • Thanks to Robert Rozumalski, the Wizard at NOAA/NWS Science and Training Resource Center for wrapping and supporting EMS-WRF in such a way that even a dumb sailor can set up and run a weather prediction model. Click here and find out what it is all about.
