1 LOCATION AND SIZE

Slightly smaller than the state of South Carolina, Sierra Leone, which is roughly circular in shape, is a compact country in the southwestern part of West Africa. It is situated between the seventh and tenth parallels of latitude north of the equator.

2 TERRITORIES AND DEPENDENCIES

Sierra Leone has no territories or dependencies.

3 CLIMATE

Because it is so close to the equator, Sierra Leone has a tropical climate; temperatures stay fairly constant throughout the year. The mean temperature is about 27°C (81°F) on the coast and almost as high on the eastern plateau. The dry season lasts from November to April, with a wet season occurring during the rest of the year. The prevailing winds from the southwest monsoon characterize the rainy season. Rainfall is greatest along the coast, especially in the mountains, which receive more than 580 centimeters (230 inches) of rainfall annually, compared to an average of approximately 315 centimeters (125 inches) in the rest of the country. During the dry season, harmattan winds blow from the Sahara Desert, bringing sandstorms but little rain.

4 TOPOGRAPHIC REGIONS

Sierra Leone's varied terrain includes the striking, mountainous Sierra Leone Peninsula; a zone of low-lying coastal marshland along the Atlantic Ocean; and a wide plains area extending inland to about the middle of the country. East of the plains, the land rises to a broad, moderately elevated plateau interspersed with occasional hills and mountains.

5 OCEANS AND SEAS

Sierra Leone is bounded on the southwest and west by the Atlantic Ocean; the country is located northwest of that part of the Atlantic Coast known as the Grain Coast, which borders Liberia.

Seacoast and Undersea Features

There are oil and gas reserves under the ocean floor off the coast of Sierra Leone.

Sea Inlets and Straits

Sherbro Island is separated from the mainland by Sherbro River on the north and Sherbro Strait on the east.

Islands and Archipelagos

There are three major island groups off the coast of Sierra Leone: the Banana Islands, the Turtle Islands, and Sherbro Island. Sherbro Island is by far the largest. The city of Bonthe is located on this island.

Coastal Features

The coast is very irregular, forming many bays, inlets, and peninsulas. The most significant features are the Sierra Leone Peninsula, where Freetown is located, and Yawri Bay, which is located in the center of the coast just south of the peninsula. The coastal plain has numerous estuaries whose river channels, like that of the Sierra Leone River, continue to flow under the sea. Mangrove swamps line much of the coast, and behind the trees, marine and freshwater swamps occupy large areas.

6 INLAND LAKES

Most of the small lakes in Sierra Leone are located in the south. The three largest and most important are Lake Sonfon, Lake Mabesi, and Lake Mape.

7 RIVERS AND WATERFALLS

Most of the rivers of Sierra Leone drain into the Atlantic Ocean; a few, however, terminate at inland lakes. Of the numerous rivers, the most important ones are the Great and Little Scarcies in the north and the Rokel in the central region. The Great Scarcies forms part of the northern border with Guinea. The Rokel River originates in the Loma Mountains and flows west to the Atlantic Ocean near Freetown. At 440 kilometers (270 miles), the Rokel is the longest river in the country. Also important are the Mano and Moro Rivers, which form the southern border with Liberia. Other major rivers include the Jong, Sewa, Soa, and Moa.

8 DESERTS

There are no deserts in Sierra Leone.

9 FLAT AND ROLLING TERRAIN

The coastal plain covers a zone varying in width from about 8 to 40 kilometers (5 to 25 miles). In the southern section of the plateau region, erosion has formed a large area of rolling terrain, which is 64 kilometers (40 miles) wide at certain points and reaches elevations between 152 and 304 meters (500 and 1,000 feet).

10 MOUNTAINS AND VOLCANOES

The mountainous Sierra Leone Peninsula, on which Freetown is located, is 40 kilometers (25 miles) long and about 16 kilometers (10 miles) wide. The highest point in Sierra Leone, Mount Loma Mansa (Bintimani), rises to a height of 1,948 meters (6,391 feet) in the Loma Mountains, which span the northeastern part of the country.

11 CANYONS AND CAVES

There are no well-known named caves or canyons in Sierra Leone.

12 PLATEAUS AND MONOLITHS

The plateau region, which encompasses roughly the eastern half of the country, has elevations ranging from roughly 304 meters (1,000 feet) to about 608 meters (2,000 feet).

13 MAN-MADE FEATURES

The most significant dam in Sierra Leone is the Guma Valley Dam, which is 68 meters (223 feet) high and supplies water to an area that includes the capital city of Freetown.
