Forecast models from sources including WeatherBug, Yr.no, and WindBorne project an overnight minimum of 22–23°C in Zhengzhou on August 30, driven by light northerly winds, partly cloudy skies, and moderate humidity that permit effective radiative cooling after daytime highs near 30°C. Recent northerly flow has accelerated the seasonal decline from peak summer warmth, aligning with late-August climatology where lows typically range 21–24°C. Trader consensus clusters tightly around these values because ensemble spreads remain narrow, with minor model differences in cloud cover and boundary-layer mixing the main sources of 1°C uncertainty. No major precipitation or frontal passage is expected to alter the outcome before resolution.
