Mbombela will record the joint-warmest conditions in the country, with temperatures climbing from 18°C to 29°C under clear skies.

Western Cape
Cape Town will enjoy clear skies with temperatures between 17°C and 21°C. Westerly winds at 10 km/h will blow steadily off the Atlantic, keeping conditions fresh and comfortable.

Weekend Outlook
Sunday will bring a continuation of clear, warm conditions across most of the country, with Johannesburg expecting a high of 28°C and an overnight low of 17°C. The warm, dry pattern will hold through Monday before a shift midweek.
