Johannesburg residents are facing another day of extreme heat as emergency services issue urgent health warnings across the city. The City of Johannesburg’s Emergency Management Services stated that persistently high temperatures are expected to continue, particularly affecting outdoor workers and vulnerable populations. Authorities have advised the public to drink plenty of water and take regular breaks in shaded or cool areas to prevent heat-related illnesses.
The South African Weather Service issued a heatwave advisory earlier this week, covering southern Gauteng. This warning indicates that dangerously high temperatures will remain in place until Friday, 13 November. The advisory serves as a formal alert for the region, highlighting the severity of the current weather conditions and the potential risks associated with prolonged exposure to the sun.
Robert Mulaudzi, a spokesperson for Johannesburg emergency services, emphasized the importance of avoiding direct sunlight during the peak heat hours. "Residents should also check on relatives and neighbours who live alone," Mulaudzi said, according to AllAfrica. He specifically urged people to stay out of the sun between 11am and 3pm. This timeframe is identified as the period when ultraviolet radiation is strongest and the risk of heatstroke is highest.
The World Health Organization’s guidelines on heat safety have been referenced in the city’s public health messaging. These guidelines identify older people, babies, and individuals with pre-existing medical conditions as being at greater risk. The organization recommends loose, light clothing, cool showers, and regular water intake. It also warns against leaving children, dependent adults, or pets in parked vehicles, even for short periods.
Emergency services have provided specific instructions for recognizing and treating heat illness. Symptoms such as dizziness, weakness, intense thirst, and headaches require immediate movement to a cool place and hydration. More severe symptoms, including confusion, seizures, or loss of consciousness, demand urgent medical assistance. In such cases, moving the person to shade and using cold, wet cloths is advised while waiting for help.
Cooler weather and thunderstorms are expected to bring relief over the weekend. Senior forecaster Tokelo Chiloane noted that these conditions will likely reduce the immediate threat. Until then, the city maintains its emergency hotline at 011 375 5911 for residents requiring ambulance or fire services.
