**Forecast models indicate a shift to cooler southerly flow on October 2, 2026, limiting Cape Town’s maximum temperature.** After northerly winds supported milder conditions on October 1, a change to southwesterly to southerly winds advects cooler marine air, with increased cloud cover, possible drizzle or light showers, and higher humidity suppressing daytime heating. Official and ensemble guidance from sources such as the South African Weather Service analogs and global models converge on a peak near 18–20 °C, consistent with the market’s leading 19 °C (29.5 %) and 20 °C (38.0 %) shares. Key variables include exact timing of the wind shift, cloud thickness, and any brief clearing that could allow modest additional warming. Model spread remains modest, supporting the tight clustering around these outcomes while acknowledging typical short-range forecast uncertainty.
