Windy is no longer reliable

You can raise a question of reliability, but it's important to point out that this would be the reliability of the weather model you used, probably the ECMWF model.
Windy offers several weather models, particularly the Australian ACCESS models, published by the Bureau of Meteorology (BoM).

Did you test them that day?
It's difficult to analyze the reason for this erroneous wind forecast several days later. But it was probably due to stormy conditions as you observed lightning and thunder. Such local conditions are usually more easily predicted by high resolution models. ACCESS C models have a resolution of 1.5 km while ECMWF has a resolution of 9 km.

When exactly, an hour or day ahead? I would personally recommend checking Wind gust layer to get more info about potential peak values.
