The radiation station is in a format that can be used on windy.com. it allows you to add custom data overlay using various formats like GeoJSON, KML,, and more.
I'm on the Nova Scotia coast in Canada. I'm pleased that the buoys are in the observations here, but as reported elsewhere they are labeled (ship) but I can easily identify them by number.
If possible in the future with buoys I think it would be very useful to show the wave data to compare with WW3 and the Euro models. In particular; Significant & Max Wave Height, and Dominant Period.
There are a few sources for data around here;

UPDATE: We were having some issue with WMO stations in general, we're sorry about that. Yesterday we fixed the problem so all the named stations are back on the map. Could you please check them as well? Thank you.
