The Cape Verde Islands are located in the mid-Atlantic Ocean some 450 kilometers (about 300 mi.) off the west coast of Africa. The archipelago includes 10 islands and 5 islets, divided into the windward (Barlavento) and leeward (Sotavento) groups. The main islands in the Barlavento group are Santo Antão, São Vicente, Santa Luzia, São Nicolau, Sal, and Boa Vista; those of the Sotavento group include Maio, Santiago, Fogo, and Brava. All larger islands but Santa Luzia are inhabited.

Three islands--Sal, Boa Vista, and Maio--generally are level and very dry. Mountains higher than 1,280 meters (4,200 ft.) are found on Santiago, Fogo, Santo Antão, and São Nicolau.

Sand carried by high winds has created spectacular rock formations on all islands, especially the windward ones. Sheer, jagged cliffs rise from the sea on several of the mountainous islands. Natural vegetation is sparse in the uplands and coast, but interior valleys support denser growth.

Rainfall is irregular, and the archipelago suffers periodic droughts and consequent food shortages. The average precipitation per year in Praia is 24 centimeters (9.5 in.). During the winter, storms blowing from the Sahara sometimes cloud the sky, but sunny days are the norm year round.
