**Forecast consensus from multiple sources points to an overnight low near 25–27°C in Chongqing on September 7 under clear to partly cloudy skies, with minimal precipitation risk.** Official and model guidance (including Chongqing Meteorological Bureau outlooks and international services) consistently show daytime highs of 35–37°C and nighttime radiative cooling limited by high humidity and urban effects, keeping the minimum in the mid-20s. Key differentiating factors include the subtropical monsoon climate’s typical late-summer diurnal range (often 8–12°C), persistent high pressure suppressing cloud cover and allowing some cooling, and the urban heat island plus Yangtze River moisture that prevents sharper drops. No significant cold fronts, typhoon remnants, or increased cloudiness are expected to alter this pattern before the 7th; a notable cooling and rain trend arrives only around the 9th–10th. Traders appear split on extremes (50% each on ≤22°C or ≥32°C) despite the tight clustering of specific-temperature probabilities around 24–27°C, likely reflecting model uncertainty in exact minimum readings at official stations versus broader-area variability or measurement timing. Historical September baselines for Chongqing show similar warm nights early in the month before seasonal cooling accelerates. Updated model runs or official Chongqing forecasts in the next 24–48 hours will be the primary near-term drivers.
