Forecast models from multiple sources indicate a likely minimum temperature near 24–25°C for Chongqing on September 1, consistent with late-summer subtropical conditions and above the historical September average low of 21–22°C. Persistent high-pressure patterns and limited cloud cover or precipitation support elevated overnight temperatures, with daytime peaks forecast at 34–36°C. The near-even market split between 18°C or below and 28°C or higher reflects residual model uncertainty in short-range guidance, particularly around any late-arriving frontal influences or urban heat-island effects that could modestly lower or sustain the minimum. Specific probabilities clustered around 21–25°C align with the consensus output, while the low odds on extremes underscore limited historical precedent for sharp early-September drops or spikes under current atmospheric setups. Updated model runs over the next 48 hours will refine the exact minimum before market resolution.
