Cotonou is the largest city in Benin. About 679,012 people officially live there, but more than two million live in the wider city area. The city is still growing, especially towards the west.

Cotonou is located in the southeast of Benin. It sits between the Atlantic Ocean and Lake Nokoué. Even though Porto-Novo is the official capital, Cotonou is where the government of Benin does most of its work.

History of Cotonou

The name "Cotonou" means "by the river of death" in the Fon language. In the early 1800s, Cotonou was a small fishing village. King Ghezo of Dahomey is thought to have officially founded it in 1830.

The village grew into an important trading center. In 1851, the French Second Republic made a deal with King Ghezo. This allowed them to set up a trading post in Cotonou. Later, under King Glele (1858–89), the land was given to the Second French Empire in 1878.

In 1883, the French Navy took over the city. They wanted to stop the British from taking control of the area. After King Glele died in 1889, King Béhanzin tried to challenge the agreement, but he was not successful. The town grew very quickly after a harbor was built in 1908. In 1960, the population was only 70,000 people.

Geography and Location

Cotonou is on a narrow strip of land. This land is between Lake Nokoué and the Atlantic Ocean. A canal called the lagoon of Cotonou cuts the city in half. The French dug this canal in 1855. There are three bridges that cross this canal. The Ouémé River also flows into the Atlantic Ocean right at Cotonou.

The city has good ways to get around. This includes air, sea, and land routes. There are also river routes to Porto Novo. These routes help Cotonou trade with nearby countries like Nigeria, Niger, Burkina Faso, and Togo.

For many years, the coast near Cotonou has been losing land to the sea. This problem got worse after the Nangbeto Dam and the deep-water port of Cotonou were built in 1961. A study showed that the coast east of Cotonou had moved back by 400 meters in 40 years. This has caused many people to move away from their homes along the coast.

Climate in Cotonou

Cotonou has a tropical wet and dry climate. This means it has two rainy seasons and two dry seasons. The rainy seasons are from April to July and from September to October. During these times, Cotonou gets about 800 to 1200 millimeters of rain each year.

In December and January, the city experiences harmattan winds. These winds are dry and dusty. Temperatures in Cotonou stay quite steady all year. The average high temperature is around 30°C, and the average low is about 25°C.
