Not a heatwave, says Saws
Despite the warm conditions, meteorologist Lehlohonolo Thobela told The Citizen that Gauteng is not currently experiencing a heatwave.
“The province is only experiencing hot conditions, but they are within the normal threshold,” Thobela said.
“Since it is spring, we are still going to see rain. There is no rain when there is a heatwave.”
Thobela explained that heatwaves occur when maximum temperatures exceed 5°C above the average for at least three consecutive days.
He urged residents to stay hydrated, avoid prolonged exposure to sunlight, and be cautious with open flames.
“We’re moving toward summer, so we can expect hot spells,” he said. “But at this point, there is no indication of an imminent heatwave.”
The weather service said that more rain is expected in the coming weeks as seasonal weather patterns shift, bringing some relief from the current hot and dry conditions across Gauteng.
