Recent forecasts from models and the South African Weather Service indicate nighttime radiative cooling under mostly clear to partly cloudy skies will set Cape Town's minimum near 9–11 °C on 26 August, with trader-implied odds clustering tightly around these thresholds. A lingering high-pressure ridge and light southerly flow limit cold-air advection from the south, while the Benguela Current and Table Mountain's orographic effects moderate extremes. Model consensus shows low spread, yet subtle differences in boundary-layer moisture and wind speed can shift the overnight low by 1–2 °C. With August climatological averages near 10 °C and no strong frontal systems expected in the next 24 hours, the balanced probabilities reflect genuine forecast uncertainty rather than a single dominant driver. Updated SAWS guidance and local station observations tomorrow morning will resolve the outcome.
