Pretoria is forecast to reach a sweltering 35°C, with Johannesburg expected to hit 33°C and Vereeniging 32°C as residents navigate the first official heatwave of the 2026/27 summer season. This extreme weather event began on Friday and has intensified throughout the weekend, affecting broad regions across Gauteng, the Mpumalanga Highveld, the southern Mpumalanga Lowveld, and the south-western bushveld of Limpopo.
Health experts emphasize that these prolonged high temperatures create significant risks, specifically heatstroke, heat exhaustion, and dehydration. Vulnerable groups, including the elderly, children, and those with underlying medical conditions, are most at risk during this period. The sustained heat places additional strain on outdoor workers, commuters, and anyone participating in sporting activities across the affected provinces.
To mitigate health risks, authorities advise staying hydrated, avoiding alcohol and excess coffee, and limiting outdoor activities during the hottest parts of the day. Residents should utilize light-coloured clothing, sunscreen, hats, and sunglasses. Inside, it is recommended to maintain proper ventilation, take cold showers, and ensure pets have constant access to fresh water and shade. According to SAWS, the Eastern parts of the country may also face isolated to scattered thundershowers, with a yellow level two warning for severe thunderstorms issued specifically for parts of KwaZulu-Natal for Sunday afternoon.
While the heat remains well above seasonal averages, forecasters expect the intensity of these conditions to begin easing after Monday. Residents are encouraged to continue monitoring official weather updates until the system clears.
