Data in Windy is correct. But the global weather models with medium resolution such as 9 km for ECMWF model cannot provide correct temperature at top of Olympus Mount 1952m, obviously. It would need to use high resolution models but they are not available in your area.
This post may help you to understand this apparent issue

I suggest that you select Meteoblue model in the point forecast table (this model is not available in the map). It takes much better the altitude into account.
