Lesotho covers 30,355 km2 (11,720 sq mi). It is the only independent state in the world that lies entirely above 1,000 metres (3,281 ft) in elevation. Its lowest point of 1,400 metres (4,593 ft) is thus the highest in the world. Over 80% of the country lies above 1,800 metres (5,906 ft). Lesotho is also the southernmost landlocked country in the world and is entirely surrounded by South Africa. It lies between latitudes 28° and 31°S, and longitudes 27° and 30°E.
Because of its altitude, Lesotho remains cooler throughout the year than other regions at the same latitude. Most of the rain falls as summer thunderstorms. Maseru and surrounding lowlands often reach 30 °C (86 °F) in summer. Winters can be cold with the lowlands getting down to −7 °C (19 °F) and the highlands to −18 °C (0 °F) at times. Snow is common in the highlands between May and September; the higher peaks can experience snowfalls year-round.
