**Trader consensus on the "Highest temperature in Cape Town on August 29" market centers on 17°C (36.5%) and 18°C (26.5%), reflecting model consensus for a mild winter day in the Southern Hemisphere.** Cape Town’s Mediterranean climate features cool, cloudy conditions in late August, moderated by the Benguela Current and prevailing southerly winds. Multiple forecasts as of August 28–29 indicate overcast skies, light southerly to southwesterly winds, and possible light showers or drizzle, limiting daytime warming. Hourly data show temperatures rising from overnight lows near 13–15°C to afternoon peaks of 16–18°C, with some runs briefly touching 19–20°C before cooling. This aligns with climatological norms for the period, where highs typically range 15–19°C absent unusual ridging or clear-sky heating. Recent model agreement across sources (e.g., peaks near 17°C midday) and the absence of strong warming signals explain the tight clustering around the leading outcomes, with lower probabilities assigned to outliers like 15°C or 19°C+ given the expected cloud cover and marine influence. Updated forecast runs or clearer conditions could shift probabilities before resolution.
