Pretoria is the transitional area between the Highveld and the Bushveld, approximately 50 kilometres (31 mi) north of Johannesburg in the north-east of South Africa. It lies in a warm, well sheltered, fertile valley, surrounded by the hills of the Magaliesberg range, 1,370 m (4,495 ft) above sea level. Pretoria covers an area of approximately 1,644 km².
ClimateThe city has a subtropical climate with long, hot summers and short cool winters. The average annual temperature is 18.74°C. This is rather high considering its relatively high altitude of 1340 metres and is due to a combination of its sheltered valley position that acts as a heat trap and also cuts off cold southerly and south-easterly winds for much of the year. Snow is an extremely rare event, which occurs once or twice in a century.
The CBDThe Central Business District (CBD) of Pretoria, South Africa is the traditional centre of government and commerce, although today most corporate office, small business, shops and many government departments can be found in the sprawling suburbs of the city rather than the CBD.
