The Mont Ventoux is the most northern mountain of the Provencial Alps. It is lying on the cross-road of geographical zones. The western side has the southern, warm and dry climate and the Mont Ventoux “bay” has a micro-climate, often even warmer and dryer than the rest of the Vaucluse.

The eastern part is also warm, but lying higher on the Sault plateau, it is more humid. The northern side is the coldest side. When the sun is up high in the summer, it can reach this part of the Mont Ventoux. In the winter however, this shadow side is cold and snow can pack up on the Mont Serein ski-station, lying on the north side of the Mont Ventoux.
