Recent forecasts from multiple meteorological sources, including ensemble models and local observations, indicate an overnight low near 22°C for Chengdu on September 1 under partly cloudy skies with light northeasterly winds and negligible precipitation. This aligns with seasonal norms as summer heat transitions, where daily minima typically range 20–23°C in early September absent strong cold-air intrusions or persistent cloud cover. Trader consensus placing notable weight on 19°C or below likely incorporates forecast uncertainty ranges and potential for localized cooling, while the clustering around 22–23°C reflects model agreement on stable conditions without major synoptic shifts in the past week. Updated model runs closer to the date will refine the exact minimum.
