Geographical Setting

Equatorial Guinea consists of two parts, an island and a mainland region. The island region consists of the islands of Bioko in the Gulf of Guinea, and Annobón, a small volcanic island south of the equator. The capital Malabo is on Bioko Island. The mainland region is Río Muni, where Bata, the largest city, and Oyala, the country's planned future capital, are located. Rio Muni also includes several small offshore islands, such as Corisco, Elobey Grande, and Elobey Chico.

Climate

More information on average rainfall and temperature for each of the climate zones in Equatorial Guinea can be seen at the Equatorial Guinea climate page.

These maps and graphs were developed from the CRU TS 3.21 dataset produced by the Climatic Research Unit at the University of East Anglia, UK. For more information see the climate resource page.

Geology

The geology map shows a simplified version of the geology at a national scale. More information is available in the report UN (1988) (see References section, below).
