Forecast models for Shenzhen on September 2 indicate overnight lows near 24–26°C under partly to mostly cloudy skies with light to moderate northerly winds and scattered showers. These conditions limit radiative cooling while advection of slightly drier air from the north supports minimums in the mid-20s°C range, consistent with September climatology of 24°C. Trader focus on 23–25°C outcomes reflects small but meaningful differences in ensemble guidance for cloud cover, wind mixing, and precipitation timing, which can shift the daily minimum by 1–2°C. No major tropical systems or cold fronts are expected to alter the pattern before resolution.
