Johannesburg will experience clear skies and crisp winter conditions on Wednesday, 15 July 2026, with temperatures ranging between 9°C and 19°C.

The national average temperature sits at 16°C, with Mpumalanga recording the warmest conditions and the Free State seeing the coldest overnight low.
What This Means for Your Day
