The Gauteng weather forecast points to a classic spring weekend. Expect warm mornings, building clouds, and thundershowers later in the day. Johannesburg and Pretoria will both see partly cloudy skies, shifting winds, and bursts of rain. The South African Weather Service (SAWS) has confirmed that Gauteng is not in a heatwave. Instead, the province faces seasonal hot spells and thunderstorms.
Gauteng Weather Outlook
Mornings will start sunny and warm, but conditions will change by afternoon. Cloud build-up will trigger showers and thunderstorms in parts of the province.
- Pretoria: Temperatures between 15°C and 31°C. Saturday carries a 30% chance of thundershowers, while Sunday has a 60% chance of rain.
- Johannesburg: Cooler than Pretoria, with highs of 25°C on Saturday and 28°C on Sunday. Saturday brings a 60% chance of rain, lowering to 30% on Sunday.
Humidity will swing from around 70–75% in the mornings to 35–40% in the afternoons before rising again in the evening. Winds will also shift, blowing from the east or north in the morning and turning westerly by evening.
Expert Insights
Meteorologist Lehlohonolo Thobela said Gauteng’s hot conditions remain within seasonal norms. He explained that a heatwave only occurs when temperatures exceed the average by 5°C or more for three consecutive days.
He noted that thunderstorms will remain common as summer approaches. “We are moving toward the rainy season, so hot spells and thundershowers will continue. At this stage, there is no sign of a heatwave,” Thobela said.
These forecasts match Gauteng’s spring climate, which often brings short but strong thunderstorms in the afternoon. Residents should stay alert for lightning, strong winds, and heavy downpours in some suburbs.
