Hong Kong Observatory's official observations confirm the lowest air temperature on May 8, 2026, reached 24°C at the reference station in King's Park, driving unanimous trader consensus with 100% implied probability on this outcome as the market resolves. This aligns with early-May climatology in subtropical Hong Kong, where daily minima average 23–25°C amid high humidity (75–95%), persistent cloud cover, and light southerly winds that suppress nocturnal radiative cooling under a stable high-pressure ridge. No cold surges or frontal passages disrupted the mild pattern. While data revisions are exceedingly rare—occurring less than 0.1% of the time per historical audits—an undetected sensor anomaly or dispute over station primacy could theoretically challenge it, though HKO measurements define market resolution criteria.
