Recent forecast model runs from agencies like the South African Weather Service and international ensembles indicate a maximum temperature of 16–17 °C for Cape Town on August 29, driven by persistent low-level stratus, light southerly flow off the cold Benguela Current, and limited insolation under overcast skies with a 30–40 % chance of drizzle. These conditions suppress daytime heating relative to clear-sky climatology, where August maxima average near 18 °C. Small differences among 16 °C, 17 °C, and 18 °C outcomes hinge on the precise timing and coverage of any breaks in cloud or brief showers, which alter surface sensible heat flux and boundary-layer mixing; stronger onshore winds or earlier clearing could briefly push readings toward 18 °C, while sustained low stratus would cap them near 16 °C. Traders appear to weight the latest model consensus most heavily.
