GAUTENG’s 7-Day Weather Forecast: 21

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

Kickstart the week with your rain jacket handy, Gauteng. Monday through Wednesday bring showers and thundershowers across the province, with Johannesburg sitting between 12 and 23 degrees on Monday and warming towards 26 by midweek. Pretoria climbs to 29 degrees during the wet spell, while Soweto and Vereeniging both hover around 26. It stays a bit unsettled and cool early on before things start settling down.

From Thursday the weather eases into partly cloudy skies, with Johannesburg reaching 27 degrees, followed by a cloudy Friday. The weekend looks the best of the week, turning partly cloudy on Saturday and mostly clear on Sunday, when Johannesburg peaks at a pleasant 28 degrees. A handy tip: keep an umbrella close for those first three days, then enjoy the drier, warmer finish.
