    • The predominant climate types are Mediterranean in the north and Saharan in the south. Four climatic sub-regions can be identified: sub-humid in the far north, semi-arid in the northwest and at Cap Bon, arid in the centre and hyper-arid and desert in most of the south. Over 40% of the country lies in the hyper-arid zone. Although average annual rainfall amounts to 220 mm, geographic variation is substantial, with regional averages ranging from 1,500 mm in the north to 50 mm in the far south, in the heart of the Sahara.
