SA’s heatwave set to peak on Monday 19 October – here’s how hot it will get

Six of South Africa’s nine provinces are currently experiencing a punishing heatwave, as eastern and central regions of the country entered a prolonged period of extreme weather. Temperatures soared on Sunday, and unfortunately, things only hot-up again for these affected areas on Monday afternoon

What defines a heatwave?

A heatwave is generally classed as an extended period of hot weather, relative to the expected conditions of the area at that time of year, which may be accompanied by high humidity. To be branded a heatwave, the unusually high temperatures must be recorded above the monthly average for more than two days in a row.
