Geography of Eritrea
Eritrea is located in the Horn of Africa and is bordered on the northeast and east by the Red Sea, on the west and northwest by Sudan, on the south by Ethiopia, and on the southeast by Djibouti. The country has a high central plateau that varies from 1,800 to 3,000 meters (5,906 to 9,843 ft) above sea level. A coastal plain, western lowlands, and some 350 islands comprise the remainder of Eritrea's land mass. Eritrea has no year-round rivers.
Hot, dry desert strip along Red Sea coast; cooler and wetter in the central highlands (up to 610 mm (24.0 in) of rainfall annually); semiarid in western hills and lowlands; rainfall heaviest during June–September except in coastal desert. The climate is temperate in the mountains and hot in the lowlands. Asmara, the capital, is about 2,400 meters (7,874 ft) above sea level. Maximum temperature is 26 °C (78.8 °F). The weather is usually sunny and dry, with the short or belg rains occurring February–April and the big or meher rains beginning in late June and ending in mid-September.

Ecoregions: Most of Eritrea's coast is part of the Ethiopian xeric grasslands and shrublands semi-desert ecoregion. The southern part of the Red Sea coast, along with the Red Sea coast of Djibouti, has been described as the Eritrean coastal desert, a harsh sand and gravel coastal strip covered in dune grasses and shrubs that is important as a channel for the mass migration of birds of prey.
