Top 3 Driest Countries in the World in 2025

The driest countries in 2025 mostly lie in the Middle East and North Africa, where desert climates dominate. These nations experience extremely low rainfall, high temperatures, and intense evaporation, shaping their ecosystems and water resource challenges. Understanding these countries is essential for grasping global water scarcity issues.

1. Egypt

Egypt is the driest country globally with an average annual rainfall of only 18 millimeters. Its desert climate causes extreme aridity, with most of the country receiving almost no rain. The Nile River is crucial for water supply and agriculture, but the vast majority of Egypt’s land remains dry and inhospitable.

2. Libya

Libya ranks second with average yearly precipitation around 56 millimeters. The Sahara Desert covers most of Libya, contributing to its hyper-arid conditions. Rainfall is rare and unpredictable, concentrating mainly in coastal mountain areas, while vast desert interiors receive virtually no rain.

3. Saudi Arabia

Saudi Arabia stands third, with average rainfall near 59 millimeters, mainly falling between November and April. Its large deserts like the Rub’ al Khali see years without any rainfall. High temperatures cause rapid evaporation, limiting water availability despite occasional short, intense rainstorms.

What is the Driest Country in the World?

Egypt tops the list in 2025 as the driest country globally, setting the standard for extreme aridity. Egypt’s desert terrain results in just 18 mm of rainfall annually, making it the driest among all nations. The country’s Nile River is its lifeline, but most of the land remains hyper-arid and inhospitable.
