Recent observational data and forecast consensus from agencies including the South African Weather Service and Met Office models show Cape Town’s minimum temperature on September 15 holding at or above 13°C amid mild conditions with light rain and winds from the northwest to southeast. This aligns with trader positioning at 100% implied probability for 13°C, reflecting real-time station readings and model runs that have not indicated any drop to 12°C. Historical September minima in the region typically range 10–12°C, but current atmospheric patterns lack the cold advection needed for a lower reading. A late-night measurement revision or localized station anomaly could still shift the outcome before final data release.
