The Republic of Equatorial Guinea is located in west central Africa. Bioko Island lies about {{convert|40|km|mi|1|sp=us}} from Cameroon. Annobón Island lies about {{convert|595|km|mi|0}} southwest of Bioko Island. The larger continental region of Río Muni lies between Cameroon and Gabon on the mainland; it includes the islands of Corisco, Elobey Grande, Elobey Chico, and adjacent islets. The total land area is {{convert|28,051|km2|mi2|abbr=on}}. It has an Exclusive Economic Zone of {{convert|303,509|km2|mi2|abbr=on}}.
Bioko Island, called Fernando Po until the 1970s, is the largest island in the Gulf of Guinea — {{convert|2017|km2|sqmi|0|sp=us}}. It is shaped like a boot, with two large volcanic formations separated by a valley that bisects the island at its narrowest point. The {{convert|195|km|mi|0|adj=on|sp=us}} coastline is steep and rugged in the south but lower and more accessible in the north, with excellent harbors at Malabo and Luba, and several scenic beaches between those towns.
On the continent, Río Muni covers {{convert|26003|km2|sqmi|0|sp=us}}. The coastal plain gives way to a succession of valleys separated by low hills and spurs of the Crystal Mountains. The Rio Benito (Mbini) which divides Río Muni in half, is unnavigable except for a 20-kilometer stretch at its estuary. Temperatures and humidity in Río Muni are generally lower than on Bioko Island.
Annobon Island, named for its discovery on New Year's Day 1472, is a small volcanic island covering {{convert|18|km2|sqmi|1|sp=us}}. The coastline is abrupt except in the north; the principal volcanic cone contains a small lake. Most of the estimated 1,900 inhabitants are fisherman specializing in traditional, smallscale tuna fishing and whaling. The climate is tropical—heavy rainfall, high humidity, and frequent seasonal changes with violent windstorms.

Climate

File:Klimadiagramm-Malabo-Aequatorial-Guinea-metrisch-deutsch.png
The climate of both the continental region and the islands is typically equatorial, with high temperatures, heavy rainfall, and much cloud cover most of the year. Local variations are due to differences in altitude and proximity to the sea. The wet seasons in the continental region are from February to June and from September to December. Rainfall is higher on the coast than inland. In Bata the rainiest months are September, October, and November, with rainfall averaging more than {{convert|94|in|mm|0|abbr=on}} a year. At Calatrava, farther south on the coast, it sometimes reaches {{convert|180|in|mm|0|abbr=on}}. Inland, however, rainfall diminishes; Mikomeseng, for example, receives only about {{convert|58|in|mm|0|abbr=on}}. The average annual temperature is about {{convert|79|F|C|1}} and is fairly constant throughout the year. The temperature maxima are somewhat lower than in Bioko. The relative humidity, however, is higher than in Bioko. Bioko has a rather debilitating climate. The so-called dry season lasts from November to March, and the rest of the year is rainy. The average annual temperature of about {{convert|77|F|C}} varies little throughout the year. Afternoon temperatures reach the high 80s °F (low 30s °C) and drop to only about {{convert|70|F|C|1}} at night. Most of the time the sky is cloudy and overcast. Extreme rainfall occurs in the south, with rain brought by monsoon winds amounting to about {{convert|450|in|mm|0|abbr=on}} a year around San Antonio de Ureca.
