From coastal deserts to river-fed oases, this list explores the seven driest places on Earth, highlighting their locations, environments, and extreme aridity. Discover these remarkable landscapes where water is scarce, yet adventure and wonder abound.
1. McMurdo Dry Valleys, Antarctica
A polar desert shaped by strong katabatic winds and unique topography, the McMurdo Dry Valleys remain one of the world’s driest regions. Snowfall rarely accumulates, creating an extreme, otherworldly landscape that fascinates scientists.
2. Atacama Desert, Chile / Peru
Average Annual Precipitation: ≈ 0.1 mm
The Atacama Desert, the driest non-polar desert, owes its extreme aridity to the cold Humboldt Current, Andes rain shadow, and persistent high-pressure systems.
3. Arica, Chile
Average Annual Precipitation: ≈ 0.76 mm
This coastal city, part of the Atacama system, receives barely any rainfall despite its Pacific Ocean location, making it one of the world’s driest inhabited places.
4. Aswan, Egypt
Average Annual Precipitation: ≈ 0.86 mm
One of Africa’s most arid cities, Aswan’s dry climate preserves ancient monuments along the Nile, offering a glimpse into Egypt’s millennia-old civilization.
5. Luxor, Egypt
Average Annual Precipitation: ≈ 1 mm
Luxor’s dry, hot climate has preserved iconic ancient sites like the Valley of the Kings, highlighting the contrast between fertile Nile banks and surrounding desert.
6. Ica, Peru
Average Annual Precipitation: ≈ 2.29 mm
Bordering the Atacama, Ica’s hyper-arid conditions protect historical artifacts and the El Huacachina oasis, a stunning contrast in an otherwise desert landscape.
7. Wadi Halfa, Sudan
Average Annual Precipitation: ≈ 4.6 mm
