Trader consensus clusters around 36–38°C for Chengdu’s August 12 high because official model guidance places the expected maximum near the upper end of seasonal norms, supported by lingering subtropical high pressure that favors clear skies and strong solar heating over the Sichuan Basin. Key differentiators among the closely matched probabilities include afternoon relative humidity above 70 percent, which can suppress further warming, variable basin topography that traps heat in urban zones, and the timing or intensity of any convective showers that could cool surfaces before peak insolation. Light winds and minimal cloud cover would push readings toward 38°C, while an earlier thunderstorm cell could cap the maximum closer to 36°C; updated National Meteorological Center runs overnight will refine these variables ahead of resolution.
