Recent forecasts from multiple models show Shenzhen's overnight low on September 2 clustered near 24–26 °C under mostly cloudy skies and light northwesterly winds, reflecting residual moisture and weak circulation from earlier tropical systems. This keeps radiative cooling modest while dew points remain elevated near 23–25 °C, limiting how far temperatures can fall. Historical September climatology places average lows around 24 °C, so current guidance aligns closely with seasonal norms absent a stronger cold surge or clear-sky episode. Traders assign near-even odds to 24 °C and 25 °C because small differences in forecast cloud timing or wind mixing can shift the minimum by 1 °C; updated high-resolution runs and local observations over the next 48 hours will narrow that spread before resolution.
