Recent forecast models from sources including the GFS and ECMWF indicate Chengdu highs on August 23 centered near 31–33°C amid the region's subtropical monsoon climate, where high humidity and basin topography trap moisture and moderate extremes through frequent afternoon convection. Scattered thunderstorms, projected with 50–70% probability, introduce the main uncertainty: earlier or heavier rainfall and thicker cloud cover favor the lower end near 31–32°C by limiting insolation, while delayed or lighter activity could permit brief clearing and peaks toward 33–34°C. Light winds and dew points near 24–26°C further constrain diurnal rises, aligning trader consensus with historical late-August baselines of 30–34°C. Updated model runs over the next 48 hours will refine resolution criteria for this short-term temperature market.
