Short-term forecast models from the Hong Kong Observatory and global ensembles indicate overnight lows of 25–27°C for July 15 amid typical July humidity, light winds, and scattered showers that suppress radiational cooling overnight. Persistent cloud cover and urban heat retention further anchor minima near the 26°C mark, while clearer intervals could allow brief drops toward 25°C. Seasonal outlooks confirm normal-to-above-normal July temperatures under ongoing warming trends, with historical July minima rarely dipping below 24°C. Traders assign the highest implied probabilities to the 25–27°C band because model consensus shows narrow uncertainty ranges, with new daily forecast updates expected to refine steering patterns and precipitation timing before resolution.
