Official forecasts from Chinese meteorological agencies indicate a daily maximum of 21–22°C in Zhengzhou on October 1, driven by recent cold air intrusions that dropped temperatures 4–8°C from late September levels. Multiple model runs and local observations align on partly cloudy to overcast conditions with light winds, keeping readings near or below the long-term October average high of roughly 21°C. This strong consensus underpins the market's near-certain positioning at 22°C or below. An unexpected warm anomaly from forecast revisions or localized heating could push the observed high to 23°C, though current data show limited scope for such deviation before resolution.
