Forecast model divergence for Chongqing on August 22 centers on afternoon convection and cloud cover in the Sichuan Basin, where surrounding mountains trap moisture and limit extreme heating under typical subtropical humidity above 70%. Official guidance from agencies like the China Meteorological Administration shows highs potentially ranging 34–37°C depending on storm timing, with recent runs indicating thundershowers that could cap peaks near 35°C while clearer intervals allow brief surges. Historical August baselines average 33–35°C, but short-term variability in steering patterns and precipitation keeps trader consensus evenly split across 32–38°C outcomes, underscoring uncertainty ahead of updated model cycles.
