The South African Weather Service (Saws) warns of flooding, winds, fire danger and extreme heat affecting Limpopo, Mpumalanga, Gauteng, Free State and Cape regions.
The weather service has released its latest weather forecast for 20 January 2026.
Here’s what you need to know.
Weather warnings: Tuesday, 20 January 2026
The weather service has issued an orange level 4 warning for disruptive rain with heavy downpours leading to flooding of susceptible roads, settlements, low-lying bridges/areas and risk of life over the northern parts of Limpopo.
Saws also issued yellow level 2 warnings for disruptive rain and severe thunderstorms, with heavy downpours leading to localised flooding of susceptible roads, settlements, low-lying areas and bridges. Major roads might experience disruption, yet they will still be accessible, likely leading to longer travel durations. Large amounts of small hail and damaging winds could result in localised damage to infrastructure.
These conditions are expected over the eastern and western parts of Limpopo, including the escarpment, as well as the Lowveld in Mpumalanga, the central and eastern parts of North West, the central Free State, south-western Gauteng, and the extreme south-western parts of Limpopo.
The South African Weather Service further issued a yellow level 1 warning for damaging coastal winds, resulting in difficulty in navigation at sea, expected between Cape Columbine and Cape Agulhas.
Fire danger warnings
Extremely high fire danger conditions are expected over the Kai! Garib Local District in the Northern Cape as well as the West Coast and in places over the City of Cape Town Local District in the Western Cape.
Advisories
Very hot and uncomfortable conditions are expected over the western parts of the Namakwa Municipal District in the Northern Cape as well as the West Coast and southwestern parts of the Cape Winelands Municipal District in the Western Cape.
