Cameroon is a country of central and western Africa. It is bordered by Nigeria to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Cameroon's coastline lies on the Bight of Bonny, part of the Gulf of Guinea and the Atlantic Ocean.
The climate varies with terrain, from tropical along the coast to semiarid and hot in the north. Exceedingly hot and humid, the coastal belt includes some of the wettest places on earth. For example, Debundscha, at the base of Mt. Cameroon, has an average annual rainfall of 405 inches (10,287 mm).
Yaoundé (/ˌjɑːuːnˈdeɪ/ or /jaːˈʊndeɪ/, French pronunciation: [ja.un.de]; German: Jaunde) is the capital of Cameroon and, with a population of approximately 2.5 million, the second largest city in the country after the port city Douala. It lies in the centre of the nation at an elevation of about 750 metres (2,500 ft) above sea level.
