Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 23°C in Chengdu on April 27, driven by official observational data from Chengdu Shuangliu International Airport, the market's resolution source under China Meteorological Administration protocols. Hourly records show the temperature peaking at 23°C in the early afternoon amid persistent cloud cover and light rain, which suppressed solar heating and deviated from initial model forecasts of 25–26°C from CMA and AccuWeather ensembles. Current evening readings near 20°C further solidify this positioning, aligning with April climatological norms of 20–25°C highs influenced by regional frontal systems. Realistic challenges include rare post-day data revisions from station audits, though such adjustments seldom exceed 1°C and require verifiable evidence. Final CMA daily summary expected within 24 hours.
