Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 18°C in Cape Town on May 1, 2026, reflecting confirmed observations from the Cape Town International Airport weather station (FACT), where automated sensors recorded a daytime peak of 18°C (64°F) under partly sunny skies with light southerly winds. This outcome aligns precisely with South African Weather Service (SAWS) forecasts predicting maximums near 18°C amid a stable high-pressure system typical for early autumn, suppressing temperatures below the monthly average of 20–22°C. While inherent uncertainties in microclimatic variations exist, realistic challenges to this positioning—such as rare post-analysis data revisions for sensor calibration—remain negligible following preliminary quality control. SAWS daily climate summary expected soon to finalize records.
