Trader sentiment clusters tightly around 21–22°C for Chengdu's March 27 high, driven by ensemble forecasts from ECMWF and GFS models converging on 21.5°C amid mild southerly flows and partial cloud cover limiting peak diurnal heating. Official China Meteorological Administration outlooks align closely, projecting 21–23°C after a recent cold front dissipated, with urban heat island effects in the Sichuan Basin nudging toward 22°C in low-wind conditions. Differentiating factors include subtle model divergences on afternoon insolation—clearer skies favor 22°C (28% implied odds), while lingering stratocumulus could cap at 21°C (27.5%) or drop to 20°C (19%)—against a March climatological average of 18°C. Upcoming 12-hourly updates may sharpen resolution criteria.
