Physical geography

Sierra Leone is located on the west coast of Africa, between the 7th parallel north, 7th and 10th parallel north, 10th parallels north of the equator. Sierra Leone is bordered by Guinea to the north and northeast, Liberia to the south and southeast, and the Atlantic Ocean to the west. The country has a total area of , divided into a land area of and water of .

Sierra Leone has four distinct geographical regions: coastal Guinean mangroves, the wooded hill country, an upland plateau, and the eastern mountains. Eastern Sierra Leone is an interior region of large plateaus interspersed with high mountains, where Mount Bintumani rises to .

Geology

Sierra Leone can be split into three geological areas, in the east is part of the West African craton, the western area consists of the Rokelides, an orogenic belt, and a 20- to 30-km coastal strip of sediments.

Extreme points

This is a list of the extreme points of Sierra Leone, the points that are farther north, south, east or west than any other location.

* Northernmost point – the northern section of the border with Guinea, Northern Province, Sierra Leone, Northern Province*
* Easternmost point – the tripoint with Guinea and Liberia, Eastern Province, Sierra Leone, Eastern Province
* Southernmost point – unnamed peninsula south of the town of Mano Salija at the mouth of the Mano River, Southern Province, Sierra Leone, Southern Province
* Westernmost point – the point at which the border with Guinea enters the Atlantic Ocean, North West Province, Sierra Leone, North West Province
* *''Note: Sierra Leone does not have a northernmost point, the border being formed here by 10th parallel north''

Climate

The climate is tropical; although it could be classified as a tropical monsoon climate, it could also be described as a climate that is transitional between a continually wet tropical rainforest climate and a tropical savanna climate.

There are two seasons; dry season (NovemberMay) and rainy season (JuneOctober).

December to January are the coolest months of the year, although temperatures can still exceed 40°C, lower to moderate humidity makes the heat around this time of the year more tolerable. Unlike March and April, the months that it gets hot and humid with temperatures around 33°C – 36°C and a solid 50% humidity, making the heat index higher than the actual temperature. The average sea temperature is 30°C.

C (6)s to year.

Average rainfall is highest at the coast, 3000–5000 mm per year; moving inland this decreases and at the eastern border of the country, the average rainfall is 2000–2500 mm.
