Recent short-range forecasts from the China Meteorological Administration and global ensembles show Beijing's August 21 high most likely reaching 32–34°C under late-summer conditions of moderate humidity, light southerly flow, and variable cloud cover with scattered thunderstorms. These factors drive the tight clustering of trader-implied odds around 33–34°C, as model spreads hinge on the precise timing and coverage of showers that could limit peak solar heating and surface warming. Historical late-August averages near 30–32°C provide context, while ensemble disagreements on convective timing sustain uncertainty between the closely matched leading outcomes without strong signals for extremes. Updated model runs and CMA briefings ahead of the date remain key variables for any shifts.
