Pretoria and the East Rand can expect similar conditions, with little relief until Thursday when skies are forecast to clear.
Limpopo
Polokwane is recording light rain with temperatures ranging from 10°C to 12°C. Strong easterly winds at 34 km/h will make it feel colder than the thermometer suggests.

Mpumalanga
Mbombela remains under light rain with a steady 13°C throughout the day. Humidity has climbed to 98%, creating foggy and misty conditions in low-lying areas. Winds are light at just 3 km/h from the southeast, but the saturated air will keep everything damp. The Lowveld and Highveld regions should prepare for slow-drying conditions and possible localised pooling on roads.
North West
Mahikeng is experiencing light rain with temperatures between 12°C and 14°C. Northeasterly winds at 16 km/h and 83% humidity are contributing to overcast skies.

Northern Cape
Kimberley is enjoying broken clouds with temperatures between 13°C and 22°C. Northeasterly winds at 28 km/h will keep the air moving, and humidity is moderate at 59%.

Eastern Cape
Gqeberha is recording clear skies and the warmest conditions in the country, with temperatures ranging from 14°C to 26°C. East-northeasterly winds at 23 km/h and 53% humidity are contributing to pleasant, dry weather.
