Today’s Weather: Warning for Severe Thunderstorms – 21 September
Widespread showers and thundershowers hit most provinces today with the Western Cape clear, while SAWS warns of severe thunderstorms and veld fire conditions.
Wet and stormy weather dominates much of South Africa today, with showers and thundershowers expected across Gauteng, KwaZulu-Natal, the Free State, Mpumalanga, North West and the Northern Cape, while Johannesburg stays cool between 12 and 23 degrees. Cape Town is the standout exception with clear skies and a warm high of 31 degrees, though Gqeberha wakes up to misty conditions and Polokwane remains cloudy. Keep an eye on the SAWS warnings today, with extreme veld fire conditions flagged alongside several minor severe thunderstorm alerts, so stay cautious whether you’re facing dry heat or the risk of storms.
