Forecast consensus from regional models points to a daytime high near 30–31°C in Zhengzhou on August 15, driven by typical late-summer monsoon conditions with scattered clouds and isolated thunderstorms that limit strong daytime heating. Historical August averages hover around 30°C, and current guidance shows no major heat-wave setup or clear-sky amplification that would push readings consistently above 32°C. Traders therefore assign the highest implied probabilities to the 31°C and 32°C-or-higher brackets, reflecting modest upside risk if afternoon sun breaks through longer than expected. Updated short-range model runs and official Chinese meteorological briefings expected later today will clarify whether any steering-pattern shift could alter the thermal profile before the daily maximum is recorded.
