Recent forecasts from numerical models and the South African Weather Service point to a daily maximum near 24–25°C in Cape Town on August 26 under partly cloudy skies and light southerly flow. A departing high-pressure ridge is allowing modest warming while limiting strong cold-air advection from the Atlantic, with ensemble spreads reflecting minor differences in cloud cover and wind timing that differentiate outcomes around 23–26°C. Historical August climatology averages near 18°C, yet recent cold-front passages have kept readings variable; traders assign the highest implied probabilities to 24–25°C precisely because these conditions sit at the upper end of the plausible range without crossing into clearer, warmer advection scenarios. Updated model runs tomorrow morning will refine the final maximum.
