Which regions of Morocco receive the most precipitation?

In Morocco, precipitation is heavily influenced by elevation and geography, with the highest levels recorded in the country's mountainous regions rather than the lowlands.1

• Mountainous Regions: The mountains capture significant moisture from North Atlantic storm systems. The central Rif mountains receive the most substantial rainfall, exceeding 80 inches (2,030 mm) annually. The High Atlas also receives significant precipitation, averaging about 30 inches (760 mm) per year. Within these ranges, slopes with a northern exposure generally receive more rainfall than those facing south.213
• Coastal Lowlands: In the broad coastal plains, rainfall is significantly lower and follows a pattern of decreasing intensity from north to south. For example, the northern Gharb plain receives approximately 32 inches (800 mm) of rain annually, while the Sous valley receives less than 8 inches (200 mm).1

Overall, rainfall in Morocco is seasonal, occurring primarily between October and April, and the mountains create a rain shadow effect that leads to abrupt desert conditions to their east.14
