A taste of spring
The warmer weather comes just days before Spring Day on 1 September. Forecaster Tokelo Chiloane said spring is typically marked by dry and windy weather.
“Spring is characterised by dry and windy weather conditions, with a frequency of heatwaves during mid-spring to late-spring, not forgetting extremely high fire danger conditions,” Chiloane explained.
These conditions are often accompanied by higher risks of veld fires, especially in regions already experiencing low rainfall.

No rain relief yet
Despite the warmer conditions, SAWS confirmed that no rainfall is expected in Gauteng this weekend.
According to Chiloane, isolated thunderstorms could begin forming in the coming weeks, although they are unlikely to bring heavy rainfall.
“By mid-September, we sometimes see the first thunderstorms in the region. However, they usually produce very little rain,” Chiloane said.
She explained that the strength of the first spring rains depends on the presence of a rain-producing weather system.
“If a rain-producing system is present, the thunderstorms might bring slightly more rainfall,” she added.
