**Trader consensus at 100% for a 23°C daily maximum in Chengdu on September 11 reflects strong agreement across meteorological models and agency forecasts.** Overcast skies, light northeast winds, and high humidity near 70-80% have limited daytime heating, keeping temperatures aligned with early-autumn climatology for the Sichuan basin. Agencies including the UK Met Office and PredictWind project a peak of 23–24°C, with current observations hovering around 19–21°C and minimal precipitation risk. Final station readings from local networks will determine exact resolution. Realistic challenges include unexpected afternoon clearing that boosts insolation or minor differences in measurement sites and reporting times, though current atmospheric stability makes significant deviation unlikely.
