Official observations from the China Meteorological Administration recorded a daily maximum of 27°C in Beijing on September 26, 2026, under conditions of moderate to heavy rain, light variable winds, and high humidity near 70-90%. This outcome aligns with real-time station data showing afternoon peaks at or near that threshold, exceeding the climatological average high of roughly 24°C for the date. Trader consensus at 100% implied probability reflects verified measurements rather than forecasts, with minimal room for revision given the convergence across multiple monitoring sites. Only an official data correction or use of an atypical station could shift resolution, though such adjustments remain historically rare for this market.
