Trader consensus on Polymarket reflects forecast model ensembles projecting Chengdu's March 29 high temperature in a tight 19–21°C range, with 21°C or higher leading at 32.5% amid a warming trend. Recent China Meteorological Administration updates and ECMWF/GFS runs indicate mild spring conditions in the Sichuan Basin, where persistent fog and low-level inversions cap daytime heating, but southerly winds could push peaks higher. Observations from the past 48 hours show highs of 18–20°C under partly cloudy skies, aligning with climatological March averages around 19°C. Key uncertainty stems from model spread on cloud cover and frontal timing; new 00Z runs expected tonight could sharpen probabilities as resolution nears.
