@eva-angel I don’t know how you get the +2 C, but in Windy you can compare the predicted temperature with the reported temperature at a weather station. It is explained here: https://community.windy.com/topic/9425/how-to-use-the-observation-vs-forecast-feature At Ivanovo you see that temperature by ECMWF model and the local WMO weather station match.
