Trader consensus around 29–30°C as the highest temperature in Chengdu on June 28 reflects short-term numerical weather prediction models showing typical late-June conditions in this humid subtropical region, where afternoon highs average near 31°C amid the East Asian monsoon. Frequent cloud cover and scattered showers—driven by moist southwesterly flow and regional low-level convergence—tend to cap daytime peaks while elevating humidity and limiting radiative heating. Ensemble spreads highlight sensitivity to exact timing of any convective activity or shifts in steering patterns, with lower probabilities assigned to extremes below 27°C or above 32°C given current observational baselines and climatological analogs. Updated model runs from agencies like the China Meteorological Administration will refine these outlooks ahead of resolution.
