Gauteng Weather

Gauteng weather

Johannesburg is situated 1 700m (about 5 580ft) above sea level. It is separated from Pretoria (1 330m or 4 400ft) by low parallel ridges and rolling hills. The weather in the north of the province is more subtropical, due to its lower altitude, and is always a few degrees warmer than Johannesburg.

Brief afternoon thunderstorms and rainfall are common in summer, but the humidity level rarely becomes uncomfortable. Winters are crisp and dry, with frost occurring in the southern areas. Snow is rare, but has occurred on some occasions in the Johannesburg metropolitan area, usually in September.
