The base map in Windy is provided by OSM (Open Street Maps). Windy cannot modify it or add anything. So better to contact them at https://www.openstreetmap.org/#map=5/44.308/-7.866

You should easily see that the Rain accumulation is the precipitation predicted for the next 10 days at maximum.
There is no way to predict annual or trimestrial precipitation !

At maximum magnification the background map shows contour lines. You just need to zoom in.
