Ensemble forecasts from major global models cluster tightly around a 22–24°C maximum for Cape Town on August 2, reflecting the current high-pressure regime and mostly clear skies that limit cloud cover while allowing moderate daytime heating. South African Weather Service guidance indicates a 20°C high under fine, cool conditions with light north-westerly flow, but ensemble spreads and slight differences in boundary-layer mixing or wind strength create the narrow uncertainty band captured by traders. With 23°C and 24°C nearly tied in market-implied odds, outcomes hinge on final observational adjustments at official stations and any late adjustments in model consensus before resolution. Historical August maxima average near 18°C, so this mild setup sits above climatology without crossing into warmer anomalies.
