The South African Weather Service (SAWS) has released its forecast for Wednesday, 21 October 2026, and residents in several provinces should prepare for very different conditions depending on where they live.
The most urgent alert centres on Limpopo, where a heat wave is gripping the Western Bushveld and is expected to persist through Friday. The province will start the day cloudy with morning fog over the south-central parts before turning warm to hot, with extremely high temperatures in the Bushveld areas. Residents there are urged to stay hydrated and limit time outdoors during peak afternoon hours.
Fire danger spreads across multiple provinces
SAWS has also flagged extremely high fire danger conditions in several regions. These include most of the North West, southern parts of the Northern Cape, the Central Karoo in the Western Cape, the Mafube local municipality in the Free State, southern Limpopo and the northwestern parts of Mpumalanga. Residents and farmers in these areas should avoid any activities that could spark a blaze.

North West and the Free State are both in for a fine but windy and warm-to-hot day.
The Northern Cape will be fine and breezy with cool to warm temperatures, becoming partly cloudy in the south and west.
The Western Cape can expect cloud cover and cool to warm conditions, with scattered showers over the south-western parts and isolated rain along the south coast and adjacent interior.
