Official observations from Cape Town International Airport, the primary resolution source via South African Weather Service (SAWS) protocols, recorded a maximum temperature of 21°C on April 16, driving unanimous trader consensus at 100% implied probability. Hourly METAR reports captured the peak around midday amid partly cloudy skies, light southerly winds, and typical autumn stability in the Western Cape, where April highs average 22–24°C under persistent high-pressure ridges. This aligns with pre-event forecasts from SAWS and NOAA models pegging 21–23°C, reflecting no anomalous heat advection or frontal influences. Realistic challenges would require rare post hoc data revisions from sensor audits or outlier peripheral stations exceeding 21°C, though airport readings hold authoritative weight; final SAWS verification is imminent for resolution.
