Recent short-range ensemble forecasts from global and regional models place Beijing's expected maximum temperature for August 2 near 33–34°C, supporting the tight market clustering around the 34°C (31.5%) and 35°C (32.5%) outcomes. Subtle differences in predicted boundary-layer mixing, incoming shortwave radiation under partly cloudy conditions, and the timing of any afternoon convection explain the narrow spread between these bins. High humidity typical of the East Asian monsoon further modulates apparent heat but has limited impact on the official dry-bulb maximum recorded by Beijing stations. Updated model runs overnight or early August 2 will likely determine whether the consensus shifts toward the upper or lower of the two leading probabilities before resolution.
