It's just like moving from California to New England :-)
You're exagerating, the confusion between the mediterranean climate and the place I come from is very frequent.
I lived in the South, but in the "other south", the South-West, oceanic and cold. Saturday it was only 13°C in Agen while it was 23°C in Wroclaw !
OK, like moving from British Columbia :)
