Temperature Extremes in the Namib Desert

The Namib Desert in southwestern Africa experiences dramatic temperature variations:

• Average annual temperature: 18–20°C (64–68°F)
• Daytime highs: Often reach 38°C (100°F)
• Nighttime lows: Can drop below freezing, to −5°C (23°F)

This extreme diurnal swing—driven by cloudless skies, low humidity, and bare ground—creates harsh conditions for life. Organisms adapt through behavioral, physiological, and morphological strategies to endure scorching days and freezing nights.
