The Western Cape lies on southern tip of Africa, extending over a substantial geographic area, from the northern West Coast region on the Atlantic Ocean to Klein Karoo. The most-southern point is at Cape Agulhas, east of Cape Town. The climate of the Western Cape is mild with gentle summers and cool winters, with rain falling between May and August. Further east and towards the north, the Klein Karoo, Olifants River and Orange River areas tend to be warmer and drier. Soil types vary across the Western Cape from granite in the Stellenbosch and Paarl districts, to limestone in the Robertson district, and shale in Swartland and West Coast areas. The rich, fertile soils along the Breede River Valley and especially the areas of Somerset West, Paarl, Stellenbosch and Franschhoek, have become renowned for their aromatic whites and punchy reds.
