Official temperature observations from Zhengzhou on August 24 confirm a daily minimum well above the 25 °C threshold, consistent with typical late-summer conditions under a strong subtropical high-pressure system that suppressed nocturnal cooling. Regional surface analyses show daytime highs near 35 °C and limited cloud cover or precipitation that would otherwise allow greater radiative heat loss overnight. With the market-implied probability exceeding 90 %, traders are aligning with verified station data rather than model uncertainty. Only an undocumented station relocation, instrument calibration error, or highly localized microclimate anomaly could alter the recorded minimum, outcomes that remain statistically rare given standardized World Meteorological Organization protocols.
