Forecast consensus from models and agencies points to a daily maximum near 31–32°C in Shanghai on August 23, aligning with the market’s leading outcomes at 48.5% and 36% implied probability. Late-August subtropical conditions typically feature high humidity, weak steering winds, and afternoon convection that can either cap peak temperatures through cloud cover and showers or allow brief clearing to push readings higher. Current extended guidance indicates scattered thundershowers, consistent with climatological averages of 31–32°C highs and supporting the tight clustering around these values while leaving room for modest downward revision if rainfall arrives earlier or intensifies. Updated model runs and official briefings in the next 24–48 hours will refine land-sea breeze and instability details that ultimately determine the exact maximum.
