Forecast models from the China Meteorological Administration and international agencies indicate Zhengzhou will reach a daily high near or above 32°C on August 21 amid late-summer monsoon humidity, light northeasterly winds, and partly cloudy skies with scattered showers. This aligns with the seasonal average high of 31–33°C for the region, where surface heating typically peaks under moderate insolation despite variable precipitation. The overwhelming market-implied odds for 32°C or higher reflect this consensus, though narrow uncertainty from timing of thundery activity or thicker cloud cover could keep maxima closer to 30–31°C. Updated model runs and real-time observations will refine the exact threshold before resolution.
