Recent forecasts from Chinese meteorological agencies and global models indicate Chongqing’s minimum temperature on August 29 will likely fall in the low-to-mid 20s °C, driven by advection of cooler northern air masses interacting with widespread rainfall. Heavy precipitation expected overnight on the 28th into the 29th promotes evaporative cooling at the surface while increased cloud cover limits daytime solar heating, lowering the daily minimum relative to prior hot, humid conditions. Model consensus clusters around 22–24 °C, with modest spread arising from variations in rain timing, intensity, and local topography that can produce small differences in overnight lows. Traders’ closely matched probabilities around 21–24 °C reflect this remaining forecast uncertainty ahead of final observational data.
