**The market consensus for a 32°C daily maximum in Hong Kong on August 4, 2026, reflects the official Hong Kong Observatory (HKO) recording of exactly that value at its headquarters station.** Early August climatology shows typical Observatory maxima of 31–33°C under the prevailing southwest monsoon, with modest day-to-day variability driven by cloud cover, humidity, and local wind patterns. On this date, surface observations aligned with the upper end of the normal range without crossing into the next bracket, consistent with model guidance and real-time station data. Traders placed overwhelming volume on the 32°C outcome once preliminary HKO readings and regional station reports became available, as the resolution criteria hinge strictly on the Observatory’s official daily maximum. Scenarios that could have altered the result—such as stronger afternoon convection lowering the peak or clearer skies pushing it to 33°C or higher—did not materialize. With the date now passed and the authoritative measurement confirmed, the near-certain pricing simply aggregates the skin-in-the-game assessment of the verified observation.
