Forecast models from sources including local meteorological agencies and international services project Shenzhen's overnight low on September 26 near 26–27°C under partly cloudy to mostly sunny conditions, with daytime highs reaching 33°C and light southerly winds. This aligns with typical late-September subtropical patterns where radiative cooling is limited by high humidity and urban heat effects, keeping minima well above 22°C. Recent observations show stable temperatures in the mid-20s overnight, with no incoming cold fronts or significant model divergences noted in official guidance. Trader emphasis on cooler bins may reflect uncertainty around localized variability or forecast updates, yet consensus data favor resolution in the 25–27°C range ahead of the day's final measurements.
