**Latest surface observations from Beijing meteorological stations confirm a daily maximum of 28°C under clear skies and light northwest winds, driving the near-certain market consensus.** Official forecasts from the China Meteorological Administration aligned closely with this outcome, showing a high of 27–28°C consistent with seasonal norms for late September and recent post-rain clearing that allowed strong daytime heating. With resolution criteria tied to verified station maxima, traders have incorporated real-time data showing the peak occurred in the afternoon before temperatures fell steadily into the evening. Only an improbable late revision to official records or an undetected microclimate anomaly at the primary reporting site could alter the result at this stage.
