The Tell Atlas enjoys a typical Mediterranean climate, warm with dry summers and mild, rainy winters with snow at upper elevations. As a consequence, the northern slopes of the Tell Atlas are forested with the endemic Abies numidica, and Atlas cedar, pine, and cork oak. In the summer a hot, dry wind, the Sirocco, blows north from the Sahara across the Tell Atlas, causing dusty, dry conditions along the northern coast of Africa.
