Which parts of Algeria receive the most rainfall?

In Algeria, the greatest amount of precipitation occurs in the mountainous regions of the eastern littoral, which are directly exposed to humid winds blowing inland from the Mediterranean.1

While annual precipitation generally increases along the coast from west to east, the highest totals are recorded in specific areas of the eastern mountains. In regions such as the Great Kabylia, Little Kabylia, and the Edough mountains, annual rainfall reaches approximately 40 inches (1,000 mm). Generally, in the area extending from about 50 miles west of Algiers to the Tunisian border, annual precipitation exceeds 24 inches (600 mm).12

Within the Atlas Mountains, rainfall is more plentiful in the Tell Atlas than in the Saharan Atlas, with the highest levels consistently found in the northeastern sections.2
