Geography and Climate

The geography of the Namibe Desert is characterized by vast expanses of sand dunes, rocky outcrops, and barren plains. Stretching along the Atlantic coast of Angola, this desert presents a dramatic contrast where the cool, nutrient-rich Benguela Current meets the hot, arid land. Sedese, located within the Namibe Desert, shares these harsh geographical features, marked by extreme aridity and sparse vegetation. Understanding the climate here is crucial: the Namibe Desert experiences very little rainfall, with some areas receiving less than 50 millimeters (2 inches) per year. Temperatures can soar during the day, often exceeding 40°C (104°F), while nights can be surprisingly cold due to the lack of humidity.

The Benguela Current significantly influences the climate of the Namibe Desert. This cold ocean current creates a temperature inversion, where a layer of cool air lies beneath a layer of warm air, inhibiting the formation of rain clouds. As a result, the coastal areas of the desert are often shrouded in fog, which provides a crucial source of moisture for some plant and animal species. This fog, locally known as “cassimbo,” plays a vital role in sustaining life in this arid environment. The interplay between the desert landscape and the oceanic influence creates a unique and challenging habitat that supports specialized forms of life. It’s this combination of factors that makes the Namibe Desert, and Sedese in particular, such a fascinating area for study and exploration.
