Official observations from the Cape Town International Airport station, the authoritative source managed by the South African Weather Service (SAWS), confirm a maximum temperature of 25°C on April 12, 2026—the highest recorded amid partly cloudy skies, light southerly winds, and typical autumn stability. This outcome matches pre-event forecast consensus from SAWS and models anticipating mild conditions with highs of 24–26°C, consistent with historical April averages around 25°C influenced by the region's southerly sea breeze regime. With market-implied odds at 100% for 25°C, traders' overwhelming consensus reflects verified instrumental data from automated sensors and quality-checked reports. Realistic challenges are minimal but could arise from rare quality assurance revisions uncovering sensor anomalies, though such adjustments for daily maxima are exceedingly uncommon.
