The market's overwhelming consensus on a 25°C high stems from the Hong Kong Observatory's official post-event temperature observations for May 16, which recorded a daily maximum of exactly that value at the primary monitoring station. This aligns with local climatological patterns for mid-May, when daytime highs typically range from 27–31°C under subtropical conditions influenced by the East Asian monsoon transition, though cooler northerly flows or increased cloud cover can suppress peaks by several degrees. Forecasters and traders incorporated the final verified data release, leaving negligible room for alternative outcomes given the precision of calibrated instruments and historical consistency in Observatory records. A shift would require an unprecedented revision to the raw measurements or a change in the defined reference station, both of which remain highly improbable based on established meteorological protocols.
