Being situated on the south-eastern seaboard of South Africa, in the province of KwaZulu-Natal, Durban is adjacent to the Indian Ocean in the east, and is bordered by the Drakensberg Mountains in the west and to the south lies the Atlantic Ocean.
Durban is characterized by a mild sub-tropical climate with warm wet summers and mild moist to dry winters. Frost does not occur in the city. However, due to large altitude variations, some western suburbs get very chilly in the winter. Durban has an annual rainfall of 1,009 millimetres (39.7 in), with daytime maxima peaking from January to March at around 28 °C (82 °F) and the minimum is about 21 °C (70 °F), dropping to daytime highs from June to August of 23 °C (73 °F) and the minimum is 11 °C (52 °F).
The metropolitan area is topographically hilly, with very few flat areas, except in the immediate vicinity of the central business district and the harbor. The western suburbs of Hillcrest and Kloof are significantly higher above sea-level, reaching up to 850 metres (2,789 ft) in the community of Botha's Hill. Many gorges and ravines are found within the metropolitan area. There is almost no true coastal plain.
