Traders see 23°C and 24°C as the most likely maxima for Cape Town on August 2 because short-range ensemble forecasts from the South African Weather Service and global models cluster around 22–25°C, well above the 17–18°C seasonal climatology for mid-winter. This warmth stems from a subtropical ridge promoting light northerly flow that advects milder continental air, combined with reduced cloud cover that enhances daytime solar heating. Sea-surface temperatures along the Benguela Current remain cool, limiting extreme spikes, while any increase in southeasterly winds or afternoon marine layer development could cap the peak near 23°C. The tight split between the two leading outcomes reflects genuine model spread in boundary-layer mixing and exact timing of any cloud build-up, with lower probabilities for 25°C+ or sub-22°C reflecting the limited likelihood of strong warm advection or an early cold front passage. Updated model runs and official guidance on August 1 will provide the final data points before the market resolves at the Cape Town International Airport station.
