Recent forecasts from the China Meteorological Administration, integrated with GFS and ECMWF model runs, place Chengdu’s May 19 maximum near 30–32°C amid typical mid-May variability in the Sichuan Basin. Persistent low-level moisture trapped by surrounding topography, combined with urban haze that reduces solar insolation by 10–20%, keeps daytime heating modest and explains why trader consensus clusters tightly around these central outcomes rather than extremes. Historical averages for late May highs hover near 28°C, but afternoon convective timing and stratus cloud thickness can shift the peak by a degree or two in either direction. Fresh model updates and Shuangliu Airport observations over the next 48 hours will refine resolution criteria tied to the official daily maximum reading.
