XyGrib for Opencpn gribs

Not sure if this has come up already but the latest XyGrib allows grib2 downloads which can be opened with the opencpn grib viewer. Well the file extension is .grb2 so assume they're grib2.

https://opengribs.org/en/xygrib

Only tried a few but manual says these are th models available >

Re: XyGrib for Opencpn gribs

I routinely download wave data in Grib (1, not 2) files and view it in OpenCPN. Has all the same functions as viewing wind (color overlays, spot data, etc.)

Yes it does (global) waves (height, period, direction) but does not display swell vs wind waves...
