Mpumalanga
Mbombela will record the nation’s highest temperature, climbing from 17°C to 31°C under clear skies. Western winds at 10 km/h will provide little relief from the heat. Residents and visitors should apply sunscreen regularly and stay hydrated, particularly during peak afternoon hours.
North West
Mahikeng will experience the coldest morning at 8°C before warming to 22°C. Clear skies and south-southwesterly winds at 15 km/h will dominate. The wide temperature range means layered clothing is essential for early commuters and schoolchildren.
Free State
Bloemfontein will face broken clouds and cooler conditions, with temperatures between 7°C and 13°C. West-southwesterly winds will strengthen to 23 km/h, and humidity will rise to 73%. The cloud cover will limit warming, keeping the province noticeably cooler than the interior north.
KwaZulu-Natal
Durban will remain under overcast skies with temperatures from 20°C to 25°C. South-southeasterly winds at 14 km/h will bring humid coastal air inland. The persistent cloud will prevent significant temperature swings, maintaining steady conditions throughout the day.
Northern Cape

Western Cape
Cape Town will receive light rain throughout Wednesday, with temperatures ranging from 15°C to 16°C. West-southwesterly winds at 14 km/h will accompany the wet conditions. Motorists should drive cautiously on slick roads, and outdoor events may require contingency planning. The rainfall marks a typical mid-May pattern as winter systems move into the southwestern Cape.
Weekend Outlook
The interior will maintain clear skies through Saturday and Sunday, with Johannesburg reaching 21°C by the weekend. Mpumalanga will stay warm but ease slightly to 20°C on Sunday. The Western Cape should see the rain system clear by Friday, with dry conditions returning for the weekend. KwaZulu-Natal’s cloud cover is expected to thin, allowing more sunshine by Saturday. Overall, the weekend will bring stable and pleasant conditions for most provinces, with only minor temperature fluctuations.
