Recent short-range forecasts from the Hong Kong Observatory and models show persistent hot, humid conditions with daily minima near 27–28 °C on August 25, driven by typical late-summer subtropical airflow, high dew points, and limited nocturnal cooling under cloudy, showery skies. Traders assign the highest implied probabilities to these values because current model consensus and climatological baselines—August overnight lows averaging ~26–27 °C—align closely with them, while above-normal seasonal temperature guidance reduces the chance of stronger cooling. Minor model spread on shower timing and intensity keeps adjacent outcomes (26 °C and 29 °C) viable but secondary, as any organized rain or wind shift would need to intensify markedly to push the minimum outside the narrow 27–28 °C window before resolution.
