Robertsport is a town in western Liberia, about 10 miles (16 km) from the Sierra Leone border.

[1] The town lies on Cape Mount peninsula, a spit of land separating the brackish lagoon Lake Piso from the Atlantic Ocean,[2] 50 mi (80 km) north-west of Monrovia.

[5] In 1849 the Liberian government signed a treaty with the Vai people,[1] acquiring the territory of Cape Mount and subsequently founding Robertsport in 1856.

[8] Since the Second Liberian Civil War, the town, still mostly a fishing village, is being developed as a seaside resort for surfing.

American visitors coming to the area after 2003 met up with a local, Robert Lomax, whom they taught to surf.

At the peak of the wet season from July to September rainfall is exceedingly heavy, with monthly averages of around 35 inches or 900 millimetres.
