I have been an avid follower of WINDY for quite some time.
I've also maintained a high level of weather interest for over 40year because of my access to direct satellite data and being a boating person. My basic comment is that this year I feel the wind projection has changed from approximately 80% to 50% reliability for a 48hr period. This mainly applies to wind speed. Personally I now prioritize my own projection again with WINDY assistance.
I know I can compare your data access with other sources , but overall the three your projections are displayed with have declined in accuracy in my area.
Thank you for your post, however Windy does not create any forecast data but instead only visualises forecast and actual data received from various third party providers.
