Short-term numerical weather prediction models from agencies like the China Meteorological Administration indicate a typical mid-August pattern for Chongqing, with subtropical high pressure and riverine topography likely supporting daytime maxima in the mid-30s Celsius. High humidity from the Yangtze and Jialing river confluence, combined with urban heat island effects and limited ventilation due to surrounding mountains, favors readings near 34–36 °C, consistent with historical August averages around 32–34 °C and recent seasonal trends. Forecast uncertainty from cloud cover, precipitation timing, and model spread keeps implied probabilities tightly clustered across 34–36 °C outcomes, while lower or higher thresholds reflect rarer deviations. Updated model runs and official briefings over the next 48 hours will refine the exact peak ahead of resolution.
