Trader sentiment for Chongqing’s June 13 maximum temperature clusters tightly around 27–29 °C because ensemble forecasts from global and regional models show daily highs most likely peaking near 28–29 °C under typical early-summer conditions. Persistent high humidity and the Sichuan Basin’s topographic trapping of moisture favor partly cloudy skies that limit strong daytime heating, while scattered showers or thunderstorms—common in the June monsoon transition—can further cap the peak by several degrees. Recent model runs indicate only modest day-to-day shifts, keeping the 28 °C and 27 °C bins nearly tied; a clearer, drier ridge would push probabilities toward 29–30 °C, whereas increased cloud cover or earlier precipitation would favor the lower side of the range. Official guidance from agencies such as the China Meteorological Administration will provide the final observed maximum used for market resolution.
