South Africa weather forecast: What to expect across provinces tomorrow

As South Africans prepare for a new week, the weather forecast for tomorrow brings a mix of winter calm and coastal turbulence. While inland regions like Johannesburg and Pretoria are expected to enjoy crisp, sunny skies after a frosty start, coastal and mountainous areas are in for a more dramatic turn.
