Traders on Polymarket are closely split around a 23-25°C high for Chengdu on March 26, with 24°C leading at 26.5%, reflecting ensemble model consensus from ECMWF and GFS forecasts clustering near 23.5°C amid a mild early-spring ridge over the Sichuan Basin. Historical March highs average 19°C, but recent warming—fueled by persistent high pressure and urban heat island effects—has narrowed the spread, differentiating outcomes via subtle model divergences: GFS implies slight afternoon clearing for 24-25°C, while CMA local guidance eyes 23°C under partial cloudiness. Diurnal range uncertainty from wind shear and boundary layer mixing keeps 22°C and 26°C viable, pending 12Z updates.
