Official observations from the South African Weather Service (SAWS) at Cape Town International Airport (FACT) confirm the highest temperature on April 15 reached exactly 21°C, driving trader consensus to 100% implied probability for this outcome. Cloudy conditions and isolated showers ahead of an intensifying cold front suppressed daytime heating, aligning with SAWS pre-event forecasts of maximums between 20-21°C—below the April climatological average of around 23°C. This positioning reflects verified hourly METAR data, with minimal wind and overcast skies limiting solar insolation. Realistic challenges would require a rare post hoc data revision from SAWS audits, though such adjustments are exceptional for established records.
