Southern Morocco has three distinct geographical areas, each with its own micro-climate. The semitropical, verdant Souss Valley is hot and humid, with temperatures ranging between 22°C and a steamy 38°C, when water vapour rises like a mist from the huge citrus groves that fill the valley. The valley is also prone to heavy winds in spring. The climate of the barren Anti Atlas veers between freezing winters and hot, dry summers. The deep southern coast enjoys a more constant year-round sunny climate.
