Recent forecasts from multiple models indicate highs near 29–30°C in Zhengzhou on August 30, driven by increasing cloud cover and moderate northeasterly winds that limit surface heating. Recent cooling from northerly flows has already dropped daily maxima below 30°C in parts of Henan, with mostly cloudy to partly cloudy skies expected to cap afternoon temperatures while keeping humidity moderate. Model consensus shows limited disagreement, though clearer breaks could push readings toward 31°C and thicker clouds toward 28°C. Traders weigh these variables against typical late-August baselines, where variable cloud regimes often produce 1–2°C spreads in observed highs. Updated short-range guidance ahead of the peak heating window will likely refine the tight 29–30°C market split.
