Short-term ensemble forecasts from major models indicate a highest temperature in Beijing on August 3 most likely between 32–34°C under humid summer conditions with scattered thunderstorms. These systems introduce uncertainty through variable cloud cover and rainfall timing, which can suppress peak daytime heating by limiting solar radiation and enhancing evaporative cooling. Recent observations show highs near 34°C on August 1 transitioning to slightly cooler, more unstable air, consistent with typical early-August monsoon influences and urban heat effects in the region. Market-implied odds cluster around these values because model runs show limited potential for clear skies that would push readings to 35°C or above, while historical analogs and current steering patterns make sub-32°C outcomes less probable absent stronger frontal passage.
