**Ensemble forecasts from GFS, ECMWF, and regional models place Beijing’s August 25 maximum near 31–33 °C, with thunderstorm development and associated cloud cover the dominant variables differentiating outcomes.** Recent warm anomalies across North China, with daytime highs frequently exceeding 33 °C earlier in August, set a warm baseline, yet increasing low-level moisture and southerly flow favor scattered convection that could cap temperatures or allow brief clearing to push readings higher. Historical climatology shows a late-August mean high of ~29.7 °C, so current guidance reflects both the seasonal tail of summer warmth and the moderating influence of precipitation. Traders assign the highest implied probabilities to 31–33 °C because these align with the central tendency of available model runs, while lower probabilities for 34 °C+ or sub-30 °C reflect realistic but less likely scenarios of suppressed convection or stronger cooling outflows. Updated short-range model cycles and official CMA guidance issued closer to the date remain the key near-term catalysts.
