Western Cape

The Western Cape is roughly L-shaped, extending north and east from the Cape of Good Hope, 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 Indian Ocean coast. 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),[7] about 10.6% of the country’s total. It is roughly the size of England or the US state of Louisiana.

The Breede, Berg and Olifants Rivers are major rivers of the province. The capital is Cape Town and other major cities include Stellenbosch, Worcester, Paarl, and George. The Garden Route and the Overberg are popular coastal tourism areas.

The Western Cape is exceptionally topographically diverse. Most of the province falls within the Cape Fold Belt, a range of sandstone folded mountains of Permian to Carboniferous age that range in height from 1000m to 2300m. The valleys between ranges are generally very fertile and contains alluvial loamy to clay soils.[citation needed] The far interior forms part of the Karoo Basin and is generally arid and hilly with a sharp escarpment in the north. Coastal areas range from sandy between capes, to rocky to steep and mountainous in places. The Western Cape is also the southernmost region of the African continent with Cape Agulhas as its southernmost point, only 3800 km from the Antarctic coastline.

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 (Afrikaans: Fine Bush). It is extremely rich in species diversity, with more plant species occurring on Table Mountain than the entire United Kingdom. It is characterised by various types of shrubs, thousands of flowering plant species and some small trees.

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 is extremely lush, with temperate rainforest (or Afromontane Forest) covering many areas adjacent to the coast and along the mountain ranges. Typical species are hardwoods of exceptional height, such as Yellowwood, Stinkwood and Ironwood trees.

Climate

The Western Cape is also diverse climatologically, with many distinct micro- and macroclimates created by the varied topography and the influence of both the Indian (warm water) and Atlantic (cold water) oceans, thus climatic statistics can vary greatly over short distances. Most of the province is considered to have a Mediterranean climate with cool, wet winters and warm, dry summers. The interior Karoo has a semi-arid climate with cold, frosty winters and hot summers with occasional thunderstorms. The Garden Route and the Overberg on the south coast have a maritime climate with cool, moist winters and mild, moist summers. Mossel Bay in the Garden Route is considered to have the second mildest climate worldwide after Hawaii.

Thunderstorms are generally rare in the province, except in the Karoo interior, with most precipitation being of a frontal or orographic nature. Extremes of heat and cold are common inland, but rare near the coast. Snow is a common winter occurrence on the higher lying ground, however frost is relatively rare in coastal areas and many of the heavily cultivated valleys.

The dependency of the Prince Edward Islands are subantarctic islands, which experience year-round cool to cold temperatures with high precipitation and little annual deviation on both accounts.
