**Official observations from the Hong Kong Observatory confirmed a daily maximum of 31°C on October 13 under clear to mostly sunny skies and light winds, aligning with pre-event forecasts of 26–32°C.** Abundant sunshine and low cloud cover allowed strong daytime heating consistent with late-summer patterns in the region, where October averages near 28°C but peaks above 30°C occur regularly. Multiple forecast models converged on this outcome days ahead, and real-time surface data showed no significant deviations. Trader consensus reached 100% on 31°C because the recorded maximum precisely matched the threshold, with minimal room for revision once quality-controlled observations are finalized. Only an unexpected station-specific anomaly or post-processing adjustment could alter the result.
