Recent ensemble forecasts from the South African Weather Service and global models highlight a dominant Atlantic high-pressure ridge over the Western Cape, promoting mostly clear skies and light southerly winds that limit daytime mixing and allow modest radiative warming. This setup supports maximum temperatures clustered around 19–21 °C on 3 August, with small differences among outcomes driven by the precise timing of any weak trough, the strength of the sea-breeze circulation off the cold Benguela Current, and overnight cloud cover that modulates the starting temperature. Historical August climatology places the long-term average high near 17–18 °C, so current guidance sits slightly above normal; traders are therefore weighting the upper end of the narrow uncertainty range while awaiting the next model cycle and local observations for refinement.
