The Western Cape (Afrikaans: Wes-Kaap; Xhosa: iNtshona-Koloni) is a province of South Africa, situated on the south-western coast of the country. It is the fourth largest of the nine provinces with an area of 129,449 square kilometres (49,981 sq mi), and the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George.
The Western Cape Province is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about 400 kilometres (250 mi) northwards along the Atlantic coast and about 500 kilometres (300 mi) eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by the Eastern Cape. The total land area of the province is 129,462 square kilometres (49,986 sq mi), :9 about 10.6% of the country's total. It is roughly the size of England or the State of Louisiana. Its capital city and largest city is Cape Town, and some other major cities include Stellenbosch, Worcester, Paarl, and George. The Garden Route and the Overberg are popular coastal tourism areas.
The Western Cape is the southernmost region of the African continent with Cape Agulhas as its southernmost point, only 3800 km from the Antarctic coastline. The coastline varies from sandy between capes, to rocky to steep and mountainous in places. The only natural harbour is Saldanha Bay on the west coast, about 140 km north of Cape Town. However a lack of fresh water in the region meant that it has only recently been used as a harbour. The province's main harbour was built in Table Bay, which in its natural state was fully exposed to the northwesterly storms that bring rain to the province in winter, as well as the almost uninterrupted dry southeasterly winds in summer. But fresh water coming off Table Mountain and Devil's Peak allowed the early European settlers to build Cape Town on the shores of this less than satisfactory anchorage.
The vegetation is also extremely diverse, with one of the world's seven floral kingdoms almost exclusively endemic to the province, namely the Cape Floral Kingdom, most of which is covered by Fynbos (from the Afrikaans meaning "Fine Bush" (Dutch: Fijnbosch), though precisely how it came to be referred to as such, is uncertain.). These evergreen heathlands are extremely rich in species diversity, with at least as many plant species occurring on Table Mountain as in the entire United Kingdom. It is characterised by various types of shrubs, thousands of flowering plant species and some grasses. With the exception of the Silver tree, Leucadendron argenteum, which only grows on the granite and clay soils of the Cape Peninsula, open fynbos is generally treeless except in the wetter mountain ravines where patches of Afromontane forest persist.
The arid interior is dominated by Karoo drought-resistant shrubbery. The West Coast and Little Karoo are semi-arid regions and are typified by many species of succulents and drought-resistant shrubs and acacia trees. The Garden Route on the south coast (between the Outeniqua Mountains and the Southern Indian Ocean) is extremely lush, with temperate rainforest (or Afromontane Forest) covering many areas adjacent to the coast, in the deep river valleys and along the southern slopes of the Outeniqua mountain range. Typical species are hardwoods of exceptional height, such as Yellowwood, Stinkwood and Ironwood trees.
