2. Libya – 56mm/year
Most of Libya, one of the countries with the lowest rainfall, is covered in desert, except for northern regions that are lucky to have a Mediterranean climate. The Jabal al Akhdar (Green Mountain) zone of Cyrenaica is where annual rainfall can reach up to 600 mm (23.6 in); however, all other areas of the country receive less, and in the Sahara Desert even less than 50 mm (1.97 in) occurs, resulting in less than 2 percent of the territory being fertile ground. The Libyan Desert has an average daytime temperature of 122 °F (50 °C) and above, and with parts of it never getting any rainfall in decades, it is one of the places with the roughest climate in the world.
