Recent forecast consensus from the China Meteorological Administration and international models places Zhengzhou’s August 21 high near 31–32 °C under persistent late-summer monsoon humidity and light northeasterly flow, aligning with the city’s climatological August mean of roughly 31 °C. This narrow temperature band, reinforced by multiple model runs showing limited diurnal cooling from cloud cover and showers, underpins the market’s near-certain assignment of probability to 32 °C or higher. The dominant driver remains the absence of any significant cool-air intrusion or heavy rain that would suppress the maximum. Only an unexpected surge in convective activity or revised observational data from official stations could realistically shift the outcome below this threshold before resolution.
