Namib
Sign in to saveThe Namib (, ; ) is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and northwest South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert.

AI overview
The Namib is a coastal desert stretching over 1,300 miles along the Atlantic coasts of Angola, Namibia, and South Africa, making it one of Southern Africa's major geographical features. It matters as a significant natural region that spans multiple countries and transitions between different ecosystems, from the Atlantic Ocean eastward toward the Kalahari Desert.

The Namib (, ; ) is a coastal desert in Southern Africa. According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and northwest South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the aridest regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and contains some of the world's driest regions, with only western South America's Atacama Desert to challenge it for age and aridity benchmarks. Most of Namibia's share of the Namib Desert is protected under the environmental protection included in the constitution of the country.
The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand dunes, some of which are high and span long, are the second-largest in the world after the Badain Jaran Desert dunes in China. Temperatures along the coast are stable and generally range between annually, while temperatures further inland are variable—summer daytime temperatures can exceed while nights can be freezing. Fogs that originate offshore from the collision of the cold Benguela Current and warm air from the Hadley cell create a fog belt that frequently envelops parts of the desert. Coastal regions can experience more than 180 days of thick fog a year. While this has proved a major hazard to ships—more than a thousand wrecks litter the Skeleton Coast—it is a vital source of moisture for desert life.
