From pleasants 20-25C to -30C in some peaks. Castilles? Snow for granted. The north? Chilly as hell. Not snowy, but the humidity fro the Atlantic will make you feel cooler than the Castilles themselves even if freezing.

Can be hard, and NOT just because of Filomena. Not all Spain it's a Mediterranean beach, trust me. Some winters in Leon can be harder than the average Winter in Poland.

How hard a Winter can be? Pick a height map of Spain... and you will deduce something by yourself.
