Sierra Leone is located on the west coast of Africa, bordered by Guinea to the north and northeast, Liberia to the southeast, and the Atlantic Ocean to the west. Covering approximately 71,740 square kilometers, the country’s terrain includes coastal plains, inland hills, plateaus, and mountains. The capital city, Freetown, is situated on a peninsula along the coast, known for its beautiful beaches.
The country’s climate is tropical, heavily influenced by the Atlantic Ocean and characterized by distinct wet and dry seasons. The rainy season typically lasts from May to October, while the dry season spans from November to April. Sierra Leone’s coastal regions experience high humidity and considerable rainfall, while the inland areas, particularly in the northeast, are drier and experience greater temperature variations. The geography and climate play a significant role in the country’s agriculture, environment, and living conditions.
