Official Hong Kong Observatory forecasts and real-time observations confirm daytime highs reaching 34°C or above across urban and New Territories stations on September 30, driven by a persistent high-altitude anticyclone delivering weak southwest winds, clear skies, and extreme heat under a Very Hot Weather Warning. Multiple stations recorded afternoon peaks of 33–35°C, aligning precisely with the 29–34°C range projected in the 9-day outlook, where urban maxima centered on 34°C with potential for 1–2°C higher inland. Trader consensus at 34°C reflects this verified trajectory from authoritative monitoring, with resolution hinging on the official daily maximum. Only an unexpected late-day cooling or station-specific anomaly below threshold could alter the outcome, though current data show no such divergence.
