Benin, officially the Republic of Benin, is a country in Western Africa which lies between the Equator and the Tropic of Cancer. It borders Togo to the west, Nigeria to the east and Burkina Faso and Niger to the north; its short coastline to the south leads to the Bight of Benin. Its size is just over 110,000 km² with a population of almost 8,500,000. Its capital is the Yoruba founded city of Porto Novo, but the seat of government is the Fon city of Cotonou. Benin was known as Dahomey until 1975.

The country can be divided into four areas from the south to the north. The low-lying, sandy, coastal plain (highest elevation 10 meters) is, at most, 10 kilometers wide. It is marshy and dotted with lakes and lagoons communicating with the ocean. The plateaus of southern Benin (altitude between 20 meters and 200 meters) are split by valleys running north to south along the Couffo, Zou, and Oueme Rivers. An area of flat lands dotted with rocky hills whose altitude seldom reaches 400 meters extends around Nikki and Save. Finally, a range of mountains extends along the northwest border and into Togo; this is the Atacora, with the highest point, Mont Sokbaro, at 658 meters.

Two types of landscape predominate in the south. Benin has fields of lying fallow, mangroves, and remnants of large sacred forests. In the rest of the country, the savanna is covered with thorny scrubs and dotted with huge baobab trees. Some forests line the banks of rivers. In the north and the northwest of Benin the Reserve du W du Niger and Pendjari National Park attract tourists eager to see elephants, lions, antelopes, hippos, and monkeys.

Benin's climate is hot and humid. Annual rainfall in the coastal area averages 36 cm. (14 in.), not particularly high for coastal West Africa. Benin has two rainy and two dry seasons. The principal rainy season is from April to late July, with a shorter less intense rainy period from late September to November. The main dry season is from December to April, with a short cooler dry season from late July to early September. Temperatures and humidity are high along the tropical coast. In Cotonou, the average maximum temperature is 31 °C (89 °F); the minimum is 24 °C (75 °F). Variations in temperature increase when moving north through a savanna and plateau toward the Sahel. A dry wind from the Sahara called the Harmattan blows from December to March. Grass dries up, the vegetation turns reddish brown, and a veil of fine dust hangs over the country, causing the skies to be overcast. It also is the season when farmers burn brush in the fields.
