The Northern Cape will experience some of the hottest conditions, with very hot weather forecast around Upington and parts of the province.
The western interior will also remain hot, while parts of the Western Cape can expect warm conditions.
Thunderstorms could affect the east
The eastern parts of the country face a greater risk of thunderstorms.
SAWS forecasts scattered thunderstorms over parts of Limpopo and Mpumalanga, with isolated to widespread activity indicated across other parts of the north-eastern interior.
KwaZulu-Natal stands out on the outlook, with widespread thunderstorm activity indicated over much of the province.
What Diwali revellers should know
SAWS has urged people planning Diwali celebrations to monitor the weather throughout the day.
If thunderstorms develop, move indoors and avoid open spaces during lightning activity.
Those celebrating outdoors in hot areas should stay hydrated, seek shade and limit prolonged exposure to the heat.
