Sierra Leone has approximately 402 km (250 miles) of coastline on the Atlantic Ocean. The coast is known for its beautiful beaches and many ports.

The country is crisscrossed by many rivers. The most important are the Rokel and the Sewa. A large part of the country is covered by tropical rainforests. These are home to rich biodiversity, including various species of plants and animals. In the eastern part of the country, there is savannah and dry areas. Sierra Leone also has several smaller islands in the Atlantic Ocean, including the Banana and Turtle islands.


Highest peak: Bintumani 1 945 m (6 381 feet) above sea level.

This mountain is located in the interior of the country in the Loma Mountains, which is part of the West African mountain system. It is also known as Loma Mansa.



Sierra Leone has two main rainy seasons during the year. The main rainy season runs from May to October, while the second, less pronounced, rainy season runs from December to April.

Temperatures here are high all year round. They average between 26°C (79°F) and 32°C (90°F), with lows around 20°C (68°F) and 24°C (75°F) at night. The warmest months are during the dry season.

The country is known for high humidity. The humid air can be particularly intense during rainy seasons. During the rainy season, Sierra Leone can face tropical storms and hurricanes, especially on the coast. Precipitation is quite significant. Annual rainfall varies from 2 000 mm (80 inches) to 4 000 mm (160 inches), which depends on the specific location.

The coast, especially around the capital Freetown, has an oceanic climate with milder temperatures and higher rainfall.


Fauna and flora:

Sierra Leone used to be home to elephant populations, but due to over-hunting and habitat loss, the country’s elephant population has been much reduced.

Leopards are among the big cats that also inhabit some parts of the country. Several species of monkeys live here, including chimpanzees, mangabeys and colobus.

There are crocodiles in the rivers and coastal areas, various species of turtles live in the sea and on the beaches, e.g. the giant loggerhead. There are many species of birds, including parrots.

The forests include a variety of tree species, including mahogany, ebony, and tropical hardwoods. Palm trees have important economic uses. Coastal areas are often overgrown with mangroves, which are important for the protection of coastal ecosystems and fisheries.



The main agricultural crops include rice, cassava, potatoes, bananas, sweet potatoes, sorghum, maize, and oil palm. Rice is the staple food for most of the population.

The country also produces coffee and cocoa, which are important export crops. Fishing is an important industry. Various types of fish and seafood are an important source of food and income for many fishermen. Oil palms are grown in Sierra Leone. Oil from these is an important raw material for the food industry and is also used in traditional African cuisine.

Pastoralism is widespread in inland areas. Livestock, especially cattle and goats, are raised for meat and milk.


Extraction of raw materials:

Sierra Leone has long been known for diamond mining. However, the diamond industry has been plagued by conflict and the illegal diamond trade, leading to the designation of “blood diamonds.” Since then, international agreements and regulations have been adopted. The country has significant reserves of iron ore, titanium, bauxite, and gold. The extraction of these raw materials plays an important role in the country’s economy and contributes to income.

There are extensive forests that provide wood for local consumption and export.



The mining of diamonds and precious stones represents a significant source of income for the country. Food and beverage production is another important sector of industry. With the development of infrastructure and construction in the country, the production of cement and building material is becoming more and more important.
