Recent forecasts from global models indicate a highest temperature in Beijing on September 26 most likely in the 26–27°C range, aligning with the market's leading probabilities for those outcomes. Afternoon peaks will depend on the timing and intensity of expected showers or thunderstorms, which limit solar heating and introduce evaporative cooling, alongside variable easterly winds and high humidity near 70%. September climatology places typical highs near 24–26°C, with current conditions reflecting a transitional autumn pattern that caps extreme warmth. Key variables tipping the distribution include model differences in convective timing and any late-day clearing that could allow brief spikes toward 28°C, with official China Meteorological Administration updates expected to refine resolution criteria ahead of market close.
