Official observations from the China Meteorological Administration, recorded at Chengdu Shuangliu International Airport—the standard resolution source for these markets—confirm the highest temperature on April 29, 2026, peaked at exactly 23°C amid persistent cloudy conditions and light winds that suppressed daytime heating. This aligns with recent forecast model consensus from CMA and international agencies like ECMWF, which projected highs in the low-to-mid 20s°C following a cooler air mass over Sichuan province. Trader consensus at 100% implied probability reflects this verified meteorological data, representing skin-in-the-game agreement on the outcome. Realistic challenges would require a rare data revision from official reanalysis, such as sensor recalibration uncovering a higher reading, though historical precedents show such adjustments affect less than 1% of daily records. Final CMA bulletin expected within 24 hours.
