The reason why I know the wind forecasts are not that good is that my

Do you pay for wind forecasts?

When you fly a light aircraft you need good forecasts and the wind ones are
much more unreliable than the cloud base and rain forecasts, free or not.
You don't rely on a forecast made the day before as it is more likely to be
wrong than right.
That is the state of wind forecasting ATM, about a day if you are (un)lucky.
