Forecast models from sources including the China Meteorological Administration and international ensembles indicate a minimum temperature for Shenzhen on September 3 centered near 23–24 °C, with scattered thunderstorms and persistent northwest flow expected to moderate overnight radiative cooling under mostly cloudy skies. High humidity near 90 % and light winds will further limit temperature drops, while any clearing could allow slightly lower readings. This narrow range explains the closely matched market probabilities around 23–25 °C, as traders weigh subtle differences in model guidance on cloud persistence and precipitation timing against typical early-September baselines of 24–26 °C lows. Updated forecasts and local observations through the night will refine the exact minimum before resolution.
