Recent model consensus from sources including the South African Weather Service and international forecasts points to a maximum of 18–19°C in Cape Town on August 7, aligning with the market’s heaviest weighting on those outcomes. In Southern Hemisphere winter, the cool Benguela Current and prevailing westerly flow typically cap daytime highs near the seasonal 17°C average, with partial cloud cover and moderate breezes further limiting solar heating. Recent runs show stable conditions without strong high-pressure ridging or clear-sky anomalies that could push readings toward 20°C or above. Traders are also factoring low precipitation chances and typical August variability, where deviations of more than 2°C from the mean remain uncommon this early in the month. New model updates or official SAWS guidance tomorrow morning represent the main near-term catalysts that could refine these probabilities before resolution.
