Last updated: Sunday 27 September 2026, 16:33 SAST – the warnings and advisories below were refreshed after SAWS issued a new high-level alert.

Gauteng is in for a proper spring weekend, with mostly clear skies over Johannesburg both days and temperatures climbing nicely. Saturday sits between 17 and 27 degrees, warming slightly on Sunday to a high of 28. Pretoria leads the pack on the warm side, reaching 30 degrees on Saturday and a toasty 32 on Sunday. Soweto stays a touch cooler and partly cloudy, topping out at 27 and then 28 degrees across the two days.

Keep an eye on Vereeniging, where showers and thundershowers are expected on Saturday before things clear up to partly cloudy on Sunday with a high of 29. If you are heading that way for the day, pack a light raincoat just in case. Otherwise it is lovely weather for getting outdoors, so enjoy the sunshine.
