Recent heavy rainfall and persistent cloud cover across the Sichuan Basin have kept Chengdu's daily highs near 26–28°C through August 18, limiting surface heating and favoring the market's clustered 29–31°C outcomes. Forecast models diverge modestly on August 20 convection timing and coverage, with the China Meteorological Administration projecting 32–35°C under partly sunny conditions while European and U.S. guidance emphasize scattered thundershowers that could cap peaks closer to 29–30°C. Key differentiating factors include boundary-layer moisture, afternoon convective initiation, and steering flow strength, all of which introduce small but resolution-critical uncertainty two days out. Trader sentiment therefore reflects the narrow range of plausible maximum temperatures given ongoing monsoon influences.
