Severe Heatwave Conditions
“The unusual heat is being driven by a slow-moving high-pressure system, which is trapping warm air over the region and pushing temperatures far above the seasonal average,” said meteorologists. Cape Town is currently experiencing a severe heatwave, with temperatures expected to reach around 40°C.
The heatwave began earlier in the week and is expected to last until around Friday, 13 March. Daytime temperatures are climbing into the high 30s and low 40s across parts of the province, with the South African Weather Service issuing an alert for heatwave conditions over parts of the Northern Cape and Western Cape.
Very hot to extremely hot temperatures, ranging from 36ºC to 42ºC, are expected across the coastal areas and adjacent interior of the Northern Cape and the western parts of the Western Cape. Specific areas are forecasted to reach alarming highs: Paarl is expected to hit 44 degrees Celsius, Stellenbosch 43 degrees, and Robertson 40 degrees Celsius.
In addition, Clanwilliam and Vredendal are also expected to reach 44 degrees, while Atlantis is predicted to reach 42 degrees, and Langebaan 40 degrees Celsius. The extreme temperatures pose significant risks to public health.
Authorities warn that prolonged exposure to extreme heat can lead to dehydration, heat exhaustion, and heatstroke. Wayne Venter explained, “Heatwave conditions are characterised by prolonged periods – at least three consecutive days or more – of temperatures exceeding the average of the hottest month by 5ºC or more.”
The hot, dry weather has already wreaked havoc in the Boland region, where firefighters are battling a blaze above the Old Pass at Du Toitskloof in Paarl. Fire officials have reported that the conditions are making firefighting efforts more challenging.
As the heatwave continues, residents are advised to take precautions to stay hydrated and avoid prolonged exposure to the sun. The situation remains dynamic, and updates will be provided as conditions evolve.
