Ensemble forecasts from the South African Weather Service and global models point to a maximum of 16–18°C in Cape Town today, driven by a weak cold front advancing southward that has boosted cloud cover and tempered northerly winds following yesterday’s 23°C peak. These conditions limit daytime heating by reducing incoming solar radiation while moderating adiabatic warming from berg winds. Trader sentiment clusters tightly around 15–17°C because small differences in frontal timing, cloud thickness, or localized sea-breeze effects—common in Cape Town’s varied topography—can shift the daily high by 1–2°C. Historical August averages near 17–18°C provide context, yet model spread in winter frontal passages keeps lower outcomes like 15°C in play until final observations confirm the peak.
