The numbers
Rain is possible over two thirds of South Africa on March 21, 2026, with significant weather warnings issued across multiple provinces. A level 4 warning for severe thunderstorms has been declared for Mpumalanga, indicating the potential for dangerous weather conditions.
In addition to Mpumalanga’s severe warning, a level 2 warning has been issued for Gauteng and parts of Limpopo, North West, Northern Cape, Free State, and KwaZulu-Natal. These alerts suggest that residents in these areas should prepare for possible severe thunderstorms, which could lead to localized flooding and other hazardous conditions.
Weather forecasts predict cloudy and warm conditions in Gauteng, accompanied by scattered showers and thundershowers. Morning fog patches are expected along the escarpment in Mpumalanga, which may reduce visibility for early commuters. Meanwhile, Limpopo is also set to experience scattered showers and thundershowers throughout the day.
North West province is anticipated to have partly cloudy and warm weather, with similar scattered showers and thundershowers expected. In the coastal regions, particularly East London and Durban, cloudy skies with scattered showers and rain are forecasted, which may impact local activities and transportation.
The expected temperatures across various cities reflect the warm conditions, with Pretoria seeing a minimum of 18°C and a maximum of 27°C. Johannesburg is forecasted to have a minimum of 17°C and a maximum of 24°C, while Vereeniging is expected to range from 16°C to 26°C. Other cities like Mbombela and Polokwane will experience similar warm temperatures, with minimums of 18°C and maximums of 24°C and 25°C respectively.
East London is projected to have a minimum temperature of 19°C and a maximum of 23°C, indicating a warm day ahead despite the rain. These weather patterns are consistent with seasonal changes typically observed in March, where transitional weather can lead to increased rainfall across the region.
As the date approaches, meteorologists and local authorities will continue to monitor the situation closely. Observers expect that the rain could provide much-needed relief to areas experiencing drought conditions, although the severity of the thunderstorms raises concerns about potential damage and safety risks. Details remain unconfirmed regarding the exact impact of the storms, as conditions can change rapidly.
