Official observations from the Cape Town International Airport weather station—the authoritative source for this market—confirm the highest temperature on May 4, 2026, reached exactly 19°C, anchoring trader consensus at a 100% implied probability for this outcome. An intense cut-off low-pressure system, as tracked by the South African Weather Service (SAWS), dominated the region with persistent cloud cover, scattered showers, and moderating westerly winds, suppressing daytime heating below May's typical highs of 20–22°C amid autumn cooling trends. This aligns with forecast model consensus prior to the date, emphasizing atmospheric stability over convective activity. Realistic challenges are negligible, requiring only a rare official data revision from SAWS, which has not occurred.
