Traders assign the highest implied probability to a 36°C peak in Chongqing on August 11 because recent numerical weather model runs from agencies such as the China Meteorological Administration and international ensembles indicate daytime maxima settling in the mid-30s amid typical late-summer subtropical conditions. Persistent high pressure and limited cloud cover support strong insolation, while regional humidity and terrain effects in the Sichuan Basin moderate extreme outliers. Historical climatology shows August averages near 33–34°C with occasional spikes above 37°C, yet current guidance lacks signals of a strong heat wave or anomalous warming that would shift odds higher. Uncertainty in boundary-layer mixing and any late-arriving moisture keeps probabilities distributed across 34–37°C outcomes, with updates from the next model cycles likely to refine the exact threshold.
