About this Market

Forecast models from sources including WeatherBug, Worldmeteo, and regional services converge on a September 7 high of 28–30°C for Shanghai under partly cloudy skies with northerly flow and modest humidity. This consensus underpins the market’s heavy weighting toward 29°C (39.5%) and 30°C (50.0%), with only slim odds on 31°C or higher. Late-summer subtropical conditions in the Yangtze River Delta typically produce highs in this range absent strong warm advection or clear-sky radiative heating; current guidance shows neither. Light precipitation chances and stable steering patterns further limit upside potential. Updated model runs over the next 48 hours will determine whether any shift in the thermal ridge or cloud cover alters the implied probabilities before resolution.
