Stable high-pressure conditions and clear skies over the Western Cape are anchoring trader consensus around a modest daily high near 19°C for Cape Town on August 24, reflected in its leading 49% implied probability. Official forecasts from multiple sources converge on afternoon peaks of 18–19°C under light south-southeasterly winds, consistent with typical late-winter climatology and recent observations showing no incoming fronts or warming advection. The 25% odds on 20°C and 20.5% on 18°C capture residual model spread and local variability around the airport versus city center, while lower probabilities for extremes underscore the narrow uncertainty range typical this time of year. Updated model runs tomorrow morning will refine the final maximum before resolution.
