Weather for Johannesburg

Best time to visit: 

Situated 550km (344 miles) from the nearest port on a vast inland plateau, 1,700m (5,700ft) high, Johannesburg's climate is much milder and drier than its latitude would suggest. The city straddles rows of jagged quartzite ridges, beneath which a century of gold mining has produced a veritable honeycomb of tunnels. Average January temperatures are 20°C (68°F). Average July temperatures are 10°C (51°F). Annual rainfall is 720mm (28.8 inches).
