Hong Kong Observatory's official observations from late May 5, 2026, confirm the highest temperature reached 23°C at key stations including the Observatory headquarters and Chek Lap Kok, driving trader consensus to 100% on this outcome amid a persistent northeast monsoon suppressing highs. This aligns with model consensus forecasts showing cool, cloudy conditions with east-southeast winds limiting daytime warming, well below May's typical average maximum of around 28°C. While measurement revisions from outlier stations are theoretically possible, they are exceedingly rare post-preliminary validation, solidifying the market's resolution based on verified meteorological data from the territory's authoritative monitoring body.
