Current forecast models from agencies like the China Meteorological Administration and global ensembles indicate a minimum temperature in Zhengzhou on September 26 near 18–20°C, driven by partly cloudy skies, light southerly winds around 3–5 km/h, and moderate humidity that limits radiative cooling overnight. These conditions create tight uncertainty between 15–18°C thresholds, as even modest increases in cloud cover or wind could suppress the drop by 1–2°C while clearer periods might allow readings near 18°C. Historical September minima average around 16°C, providing context, though recent stable high pressure favors the warmer side of the range. Updated model runs and official observations before midnight will likely refine trader consensus on the exact low.
