Recent forecasts from the South African Weather Service and preliminary models point to partly cloudy conditions turning fine over Cape Town on August 15, supporting maximum temperatures clustered around the seasonal average of 17–18°C. This keeps the 18°C, 19°C, and 20°C outcomes tightly bunched in trader pricing, with subtle differences driven by Atlantic wind strength, cloud-cover timing, and solar heating under a high-pressure ridge versus any lingering post-frontal moisture. Historical August data show daily highs rarely exceed 22°C or fall below 15°C in the absence of strong systems, underscoring why markets assign low probability to extremes. Updated model runs and official observations tomorrow will refine these narrow ranges ahead of resolution.
