Current meteorological forecasts for Chongqing on September 4 point to overnight minimum temperatures in the mid-20s°C range, with multiple models converging on lows near 24–26°C amid mostly cloudy skies, light easterly winds, and dew points supporting limited radiative cooling. Chongqing’s basin topography and urban heat island effects sustain elevated nighttime readings during the early-September transition from peak summer warmth, consistent with historical September averages of roughly 21–22°C lows. Trader sentiment clusters tightly around 23–24°C outcomes due to minor model spreads on cloud cover and wind patterns that could nudge the exact minimum by 1–2°C, while the low probability assigned to 19°C or below reflects the absence of any cooling fronts or significant precipitation in the short-term outlook. Updated model runs and observational data over the next 48 hours will refine resolution criteria.
