Benin, a narrow, north-south strip of land in West Africa, lies between the Equator and the Tropic of Cancer. Benin's latitude ranges from 6o3oN to 12o30N and its longitude from 10E to 3o40E. Benin 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 square kilometers, roughly the size of Pennsylvania, Benin extends from the Niger River in the north to the Atlantic Ocean in the south, a distance of 700 kilometers. (about 500 mi.). Although the coastline measures 121 kilometers. (about 80 mi.), the country measures about 325 kilometers. (about 215 mi.) at its widest point. It is one of the smaller countries in West Africa: eight times smaller than 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 (average elevation 200 meters).
The country can be divided into four main 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 comprised 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 31oC (89oF); the minimum is 24oC (75oF).
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.
