Benin, a narrow, key-shaped, north–south strip of land in West Africa, lies between the Equator and the Tropic of Cancer. Its latitude ranges from 6°30′ N to 12°30′ N and its longitude from 1° E to 3°40′ E. It is bounded by Togo to the west, Burkina Faso and Niger to the north, Nigeria to the east, and the Bight of Benin to the south.
With an area of 112,622 km2 (43,484 sq mi), it is slightly bigger than the nation of Bulgaria. It extends from the Niger River in the north to the Atlantic Ocean in the south, a distance of 700 km (435 mi). Although the coastline measures 121 km (75 mi), the country measures about 325 km (202 mi) at its widest point.
It is one of the smaller countries in West Africa, about one eighth the size of Nigeria, its neighbor to the east. It is, however, twice as large as Togo, its neighbor to the west. A relief map of Benin shows that it has little variation in elevation, averaging 200 m (656 ft) in elevation.
Biogeography
Topography of Benin
The country can be divided into four main areas from the south to the north. The low-lying, sandy, coastal plain, which has a highest elevation of 10 m (33 ft) is, at most, 10 km (6 mi) wide. It is marshy and dotted with lakes and lagoons connected to the ocean. The plateaus of southern Benin, with an altitude ranging between 20 and 200 m (66 and 656 ft), are split by valleys running north to south along the Couffo, Zou, and Oueme Rivers, an area that has been categorised by the World Wildlife Fund as part of the Guinean forest-savanna mosaicecoregion. Then an area of flat lands dotted with rocky hills whose altitude seldom reaches 400 m (1,312 ft) extends around Nikki and Savé. Finally, the Atacora mountain range extends along the northwest border and into Togo with the highest point, Mont Sokbaro, at 658 m (2,159 ft).
Benin has fields 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. The country formerly offered habitat for the endangered painted hunting dog, Lycaon pictus,[1] although this canid is considered to have been extirpated from Benin due to human population expansion. Woodlands comprise approximately 31 percent of Benin's land area.[2]

Benin's climate is hot and humid. Annual rainfall in the coastal area averages 1,360 mm (53.5 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 (87.8 °F); the minimum is 24 °C (75.2 °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 is also the season when farmers burn brush in the fields.
