Why is the coastal plain of Dhofar fertile?

The coastal plain of Dhofar is considered the most fertile area in Oman primarily due to the influence of the summer monsoon climate. This seasonal weather pattern provides the region with consistent moisture, which, combined with the presence of constantly flowing streams, supports temperate vegetation.12

Additionally, the plain is characterized by fertile alluvial soil. This unique combination of water availability and soil quality allows for a productive agricultural environment that contrasts with the arid conditions found in much of the rest of the country.31
