Latest China Meteorological Administration forecasts project a sunny day in Chongqing on April 4 with a high of 28°C under light northeast winds below 12 km/h, anchoring trader sentiment toward the closely contested 26-28°C outcomes and implying 75% probability for these buckets. This reflects model consensus from GFS and ECMWF ensembles showing upper-20s peaks amid subtropical ridging aloft promoting subsidence and strong diurnal heating in the city's heat-trapping basin topography, though discrepancies arise from varying predictions of afternoon cloud cover and boundary layer mixing that could cap peaks at 26-27°C. Airport observations at Chongqing Jiangbei International— the market's resolution station—typically lag urban maxima slightly; overnight updates and morning soundings will refine odds before peak heating around 2-4 p.m. local time. Historical April highs average 23°C, underscoring the warming trend driving current elevated implied probabilities.
