Seasonal winter conditions in the Southern Hemisphere keep Cape Town's typical August daily maxima near 17–19°C, with current forecast models from the South African Weather Service and international sources converging on a 16–18°C peak for August 22 under partly to mostly cloudy skies, light northwest winds, and minimal drizzle risk. This consensus aligns with the market's leading outcomes at 18°C (42.5%), 19°C (23.5%), and 17°C (21.5%), reflecting trader weighting of climatological baselines and limited short-term warming signals from recent cold-front passages. Higher probabilities for 20°C+ remain low absent significant model shifts before resolution, while cooler outliers below 16°C carry reduced odds given the narrow expected range.
