Current ensemble forecasts for Cape Town on August 23 indicate a maximum near 18–19°C, driven by high-pressure ridging and southerly flow that favors partly cloudy to clear conditions with limited warming. Recent model runs show minor spread from subtle differences in boundary-layer mixing and afternoon cloud timing, keeping 18°C and 19°C outcomes closely matched in trader consensus. Historical August maxima average near 18°C, and no significant frontal systems are expected in the short term. Updated SAWS guidance and next ECMWF/GFS cycles will likely refine the peak value ahead of market resolution.
