Recent numerical weather prediction model runs from the China Meteorological Administration indicate a typical late-summer pattern over Chongqing, with subtropical high pressure supporting daytime maxima near 35–37 °C on August 11 amid high humidity and limited cloud cover. Local topography—steep valleys and the Yangtze River basin—traps heat and suppresses ventilation, while weak steering flows allow gradual warming unless scattered convective showers develop and lower temperatures by 1–2 °C. Ensemble spread in guidance creates the tight clustering between the 36 °C and 37 °C outcomes, as small shifts in timing of any monsoon moisture or afternoon convection could tip the daily peak either way. Historical August averages near 34 °C provide baseline context, but current conditions favor the upper end of the distribution.
