Recent forecasts from multiple models indicate a highest temperature in Chengdu on September 17 likely between 24–27 °C, with trader consensus clustering around 26 °C amid persistent cloud cover and light rain or showers. The region remains under the influence of a broad trough and residual moisture from earlier western China rainfall, which limits daytime heating and keeps maximums near or slightly below seasonal averages of about 25 °C. Key variables differentiating the close 25–27 °C outcomes include the exact timing and coverage of afternoon clearing versus lingering stratiform clouds, as well as minor model differences in boundary-layer moisture and wind direction. Updated runs from agencies such as the China Meteorological Administration and global ensembles expected in the next 24–48 hours will refine the peak reading before market resolution.
