Forecast models from agencies like the China Meteorological Administration cluster Chongqing’s August 23 maximum temperature in the mid-30s Celsius, primarily due to a persistent subtropical high-pressure ridge and weak steering flow across the Sichuan Basin that limits ventilation while high humidity curbs nocturnal cooling. This setup aligns with August climatology, where daily highs typically average 34–36°C and occasionally reach 37–38°C under similar patterns. Trader consensus, reflected in the 72.5% implied probability for 37°C, emphasizes these conditions over recent stable ensemble guidance, while the 25.5% on 38°C or higher accounts for residual model spread and potential short-term intensification before official observations resolve the market.
