The South African Weather Service (SAWS) says the intense heat currently affecting parts of KwaZulu-Natal may be linked to climate change, as the province continues to experience unusually high temperatures.
A heatwave advisory has been in place for northern regions, with forecasters warning that although the alert is set to expire on Friday, conditions will remain hot.
SAWS forecaster Ayanda Nsele said temperatures are expected to stay just below official heatwave thresholds but will still be uncomfortably warm in the coming days. Areas such as Ladysmith and Ulundi are forecast to record maximum temperatures of between 38°C and 39°C.
“Even though the heatwave advisory is ending, it does not mean temperatures will drop significantly,” Nsele explained. “It simply means they will fall below our heatwave criteria. Conditions will remain fairly warm into next week.”
Emergency services in and around Durban have reported several incidents of people collapsing due to extreme heat and humidity, particularly among children and the elderly.
ALS Paramedics spokesperson Garrith Jamieson said many cases are linked to dehydration and urged residents to take precautions.
“As you sweat, you lose fluids and need to rehydrate regularly,” Jamieson said. “Drink plenty of water, avoid unnecessary exposure to the sun during peak hours, and take extra care of the elderly and young children, who are more vulnerable to dehydration.”
Authorities are advising residents to stay hydrated, limit outdoor activity during the hottest parts of the day, and seek shade or cooler environments where possible, as above-average temperatures persist across the province.
In short: it’s less ‘mild summer’s day’ and more ‘carry-a-water-bottle-at-all-times’ weather.
