Equatorial Guinea lies on the west coast of Africa, bordering the North Atlantic Ocean, with Cameroon lying to the north and Gabon to the east and south.

The mainland consists of coastal plains rising to interior thickly forested hills. The most important part of Equatorial Guinea is the island of Bioko which is formed from three extinct volcanoes.
The nation's capital, Malabo, is situated here.

Both the mainland and the islands have a typical equatorial climate with high temperatures, high humidity, heavy rainfall, and much cloud around the year. Annual rainfall is around 2,000 mm/80 in.
