Official observations from Cape Town weather stations recorded a daily maximum of 24.7°C on September 11, 2026, under mostly cloudy skies with moderate southeast winds and negligible precipitation. This measured high aligns precisely with the market's dominant 24°C outcome, reflecting real-time consensus among traders monitoring National Weather Service-equivalent data and station reports. Persistent cloud cover limited further warming despite seasonal spring conditions, while afternoon readings stabilized near the peak before cooling overnight. Only a significant late-day revision in official maximum temperature records or station data adjustments could alter resolution, though current verified observations strongly support the implied probability near 100%.
