Forecast models from the China Meteorological Administration and international ensembles indicate Beijing's October 11 high will likely reach 26–27°C under mostly cloudy to partly sunny skies with light southerly to southeasterly winds. This autumnal pattern features modest daytime heating without strong warm advection or cold-air intrusion, keeping values near seasonal norms slightly above the long-term October average. The near-even split between 27°C (42%) and 26°C (38.5%) reflects minor differences in model handling of cloud cover timing and boundary-layer mixing, which can shift the daily maximum by 1°C. Updated runs ahead of the event will clarify whether afternoon clearing boosts readings toward the higher end or persistent clouds cap them lower.
