Why the Namib Desert Is Cooler Than the Kgalagadi: Coastal vs. Inland Climate

The Namib Desert (coastal, Atlantic) is cooler than the inland Kgalagadi Desert due to the Benguela Current—a cold ocean current that chills onshore air, creating frequent fog and moderating temperatures.

• Namib average: ~20°C (68°F)
• Kgalagadi average: ~30°C (86°F)

The Kgalagadi, far from oceanic influence, experiences greater solar heating and temperature extremes typical of continental interiors.

Coastal deserts worldwide (Atacama, Namib, Sonoran coast) share this cooling effect, while inland deserts (Sahara, Gobi, Kgalagadi) are hotter.
