Gauteng heatwave warning: Temperatures to hit 35°C

Gauteng residents have been warned of extreme heat, with temperatures set to climb to 35°C, the province's first heatwave of the 2026/27 summer. The heatwave, beginning Friday, is expected to peak on Sunday, with Pretoria reaching the highest temperature at 35°C, followed by Johannesburg at 33°C and Vereeniging at 32°C. Southern Mpumalanga Lowveld and Limpopo's bushveld regions may also experience high temperatures.

Health experts caution that prolonged exposure to high temperatures can cause dehydration, heat exhaustion, and heatstroke, especially for children, the elderly, and those with pre-existing health issues. Residents are advised to drink ample water, avoid alcohol and large amounts of coffee, and consume cold, light meals. Spicy foods should be limited, and outdoor activities should be minimized during peak heat hours.

Authorities recommend seeking shade or shelter, wearing protective clothing like sunscreen, sunglasses, hats, and loose-fitting garments, and taking cold showers. Home and workplace ventilation should be ensured. Pet owners are reminded to provide animals with shade and fresh water at all times.

This heatwave is one of the hottest in Gauteng since spring started and may strain outdoor workers, commuters, and sports participants. Residents are advised to check weather updates and take necessary precautions to stay safe during this extreme weather event. The heatwave is expected to persist through Monday before temperatures start to decline.
