Official forecasts from the Hong Kong Observatory project a daily minimum of 26–27°C for October 15 under a moderate easterly airstream, partly sunny skies, and humidity levels of 65–85%, consistent with regional model runs showing limited nocturnal cooling. Current observations and hourly data place overnight lows near 26°C without significant drops, aligning with climatological norms for mid-October in the subtropical region. Trader consensus at 96% implied probability for 26°C reflects this stable pattern and the low likelihood of rapid changes from steering winds or precipitation. A shift in cloud cover increasing radiative cooling or localized measurement variations at official stations could realistically push the recorded low to 25°C or 27°C before resolution.
