Limpopo
Polokwane enjoys clear skies with temperatures climbing from 12°C in the early morning to 27°C by afternoon. South-southeasterly winds at 11 km/h will provide some relief from the warmth. The province experiences one of the wider temperature ranges today, so layered clothing is advisable for those starting their day early.
Mpumalanga
Mbombela records the nation’s highest temperature at 30°C, rising from a morning low of 18°C under few clouds. Easterly winds at 9 km/h and humidity at 40% will create warm but not oppressive conditions. The Lowveld region should prepare for strong afternoon heat, particularly in valleys where temperatures may feel warmer.
North West
Mahikeng sees clear skies with temperatures between 13°C and 26°C. Northeasterly winds at 7 km/h will be gentle, and the 41% humidity level indicates dry, comfortable conditions. This province joins the interior trend of cool mornings giving way to warm, sunny afternoons.
Free State
Bloemfontein experiences clear conditions with the coolest morning temperature in the interior at 11°C, warming to 25°C by mid-afternoon. Light west-northwesterly winds at 3 km/h mean virtually calm conditions. Residents should prepare for a significant temperature swing of 14 degrees between morning and afternoon.
KwaZulu-Natal
Durban faces broken clouds and strong southerly winds reaching 26 km/h, the highest wind speed nationally. Temperatures will range from 20°C to 23°C with elevated humidity at 75%, creating conditions that will feel cooler than the actual temperature. Coastal areas from the South Coast to the North Coast should expect choppy sea conditions.
Northern Cape
Kimberley enjoys clear skies with temperatures between 15°C and 27°C. Northerly winds at 12 km/h and low humidity of 39% will produce dry, warm conditions typical of the province. The northern parts of the province can expect similar sunny weather with excellent visibility.
Eastern Cape
Gqeberha sees broken clouds with a narrow temperature range of 16°C to 18°C. South-southwesterly winds at 12 km/h and high humidity of 85% will create cool, damp conditions along the coast. Inland areas such as Makhanda and Graaff-Reinet will be warmer but still cloudier than the interior provinces.
Western Cape

Strong south-southeasterly winds at 24 km/h and 79% humidity will make conditions feel significantly cooler, particularly in exposed coastal areas.

Weekend Outlook
Saturday will bring clear skies to Johannesburg with temperatures between 15°C and 24°C, while Sunday improves further with temperatures reaching 25°C under clear conditions. Most interior provinces can expect settled, sunny weather across the weekend, making it favourable for outdoor plans.
