Current forecasts for Cape Town's overnight low on August 29 center on 11–13°C amid overcast skies, light showers or patchy rain, and moderate southerly to southwesterly winds of 10–20 km/h that limit radiative cooling. Official guidance from sources such as the Met Office and local models shows a nighttime minimum near 12°C, with some projections dipping to 11°C under clearer breaks or rising to 13°C if cloud cover persists. This tight clustering of market-implied odds around those three outcomes reflects genuine uncertainty in the precise timing of any clearing, dew-point depression, and urban heat-island effects versus marine influence. Traders are weighting recent hourly trends showing temperatures already falling into the mid-teens by afternoon against climatological August baselines near 10–12°C.
