Is Windy.com accurate?
The power-user favourite for its animated maps, used by pilots, sailors and weather enthusiasts.
Windy.com is as accurate as the model you pick - it shows the raw ECMWF, GFS and ICON models directly rather than hiding them. Our tested scoreboards tell you which of those is verifying best where you are.
How Windy.com makes its forecast. Windy is the honest one: it does not invent a forecast, it lets you pick and display the raw models directly - ECMWF, GFS, ICON and more. That is exactly the philosophy behind checkweather.io. That matters, because it means the accuracy you get from Windy.com is really the accuracy of the models underneath it - the same models we test, in the open, against the recorded weather.
Our verdict. Because Windy shows the real models, its accuracy is simply the accuracy of whichever model you select. Our scoreboards tell you which of those models is verifying best where you are right now.
