I use a bunch of different sources if I need an accurate wind forecast.
If time fishing the big pond, I usually just stick with the Windy app. Anyone who uses this app need to be aware of the different weather models this app uses. You can change the weather model from ECMWF to GFS, NAM and others. It’s helpful to understand the tendencies of each model because they will very likely give you different forecasts.
If I’m fishing the BIG POND, I use the Wind Alert app first. This one also has the option of choosing the different weather models but it also has an option to blend them which is what I prefer.
On top of the Wind Alert app I will use the Windy app because it also gives wave forecasts and is very convenient because it shows the wind forecast on the map. I will also occasionally use the NOAA marine forecasts in addition to Windy and Wind Alert.
If instant to see what the current wind is I use MyRadarPro app. It opens fast and gives you a good idea of what the current winds and directions are.
