How does elevation create different climates across Eritrea?

Eritrea’s diverse climatic conditions are primarily driven by significant variations in elevation, which create a stark contrast in temperatures across the country.1

The impact of elevation is most evident when comparing the coastal regions to the central highlands. For example, the coastal city of Massawa experiences some of the highest average temperatures in the world, typically in the mid-80s F (about 30 °C). In contrast, Asmara—located only 40 miles away but situated roughly 7,500 feet (2,300 meters) higher on the plateau—enjoys a much cooler climate, with averages in the low 60s F (about 17 °C).1

Elevation also influences precipitation patterns. The central highlands receive more annual rainfall (16 to 20 inches) compared to the western plains, which receive less than 16 inches. Furthermore, the eastern edges of the plateau and coastal fringes receive limited rainfall from a northeasterly airstream during winter and spring, while the interior Danakil Plain—which includes areas below sea level—remains almost entirely rainless.12
