Hong Kong Observatory's official observations confirm the highest temperature on April 4, 2026, reached 26.4°C at its headquarters station, with peaks up to 26.8°C at select automated sites like Lau Fau Shan and Wong Tai Sin, anchoring trader consensus at 99.4% implied probability for the 26°C outcome. This aligns with early forecasts of 22–26°C amid cloudy conditions, showers, and a thunderstorm warning that capped daytime heating despite above-normal seasonal trends for April. The market reflects verified instrumental data from calibrated thermometers, with resolution tied to HKO's highest reading. Realistic challenges include rare post-audit data revisions uncovering a higher unlogged peak, though standard quality controls make this improbable; final monthly summary expected soon.
