Recent forecast model runs from agencies including the China Meteorological Administration point to maximum temperatures in Chongqing on July 29 centering on 37–39 °C, with probabilities clustered tightly because of uncertainty in cloud cover and convective activity. Thunderstorm development expected later in the day could limit peak solar insolation and cap daytime highs near 36–37 °C, while clearer morning conditions under the regional subtropical high might allow readings to reach 38–39 °C. The city’s topographic basin setting and pronounced urban heat island effect amplify baseline warmth, yet higher humidity and potential precipitation introduce variability that traders weigh against historical July maxima averaging 34–37 °C. Updated model guidance and observational data over the next 48 hours will likely refine these closely matched outcomes.
