Forecast models from agencies including the China Meteorological Administration indicate Zhengzhou will likely see a daily maximum near 30–31°C on August 21 amid partly cloudy skies, scattered thundery showers, and light northeasterly winds that reduce solar insolation and surface heating. Historical August averages near 31°C provide context, but afternoon convection and variable cloud cover introduce uncertainty that could either suppress peaks below 31°C or allow brief clearing to reach 32°C. These factors explain the tight market clustering around the 30°C (50.0%), 31°C (49.0%), and 32°C+ (48.5%) outcomes, with traders weighting the latest ensemble guidance and typical late-summer humidity patterns that limit extreme excursions.
