Trader consensus on Polymarket overwhelmingly backs a highest temperature of 22°C in Chengdu on April 30, 2026—at Chengdu Shuangliu International Airport—as reflected in near-certain 100% implied probability, driven by real-time observational data from the China Meteorological Administration showing midday peaks near 21°C amid persistent overcast skies, 99% cloud cover, light rain, and north-northeasterly winds that suppress solar insolation and convective heating. ECMWF and GFS ensemble forecasts align with a daytime maximum of 22–23°C under this cooler synoptic pattern in the Sichuan Basin, below April's historical average of 23–24°C. Final resolution awaits post-midnight CMA observations via Wunderground; a rare sudden cloud break allowing brief afternoon warming to 23°C remains a low-probability outlier per model uncertainty ranges.
