Liberia is situated in West Africa, bordering the North Atlantic Ocean to the country's southwest. It lies between latitudes 4° and 9°N, and longitudes 7° and 12°W.
The landscape is characterized by mostly flat to rolling coastal plains that contain mangroves and swamps, which rise to a rolling plateau and low mountains in the northeast. Tropical rainforests cover the hills, while elephant grass and semi-deciduous forests make up the dominant vegetation in the northern sections. The equatorial climate is hot year-round with heavy rainfall from May to October with a short interlude in mid-July to August. During the winter months of November to March, dry dust-laden harmattan winds blow inland, causing many problems for residents.
Liberia's watershed tends to move in a southwestern pattern towards the sea as new rains move down the forested plateau off the inland mountain range of Guinée Forestière, in Guinea. Cape Mount near the border with Sierra Leone receives the most precipitation in the nation.The country's main northwestern boundary is traversed by the Mano River while its southeast limits are bounded by the Cavalla River. Liberia's three largest rivers are St. Paul exiting near Monrovia, the river St. John at Buchanan and the Cestos River, all of which flow into the Atlantic. The Cavalla is the longest river in the nation at 320 miles (515 km).
