Recent forecasts from the China Meteorological Administration and other models indicate multi-cloud conditions over Beijing on September 25, with highs most likely between 25–27 °C under northeast winds. Cloud cover will limit surface heating compared with clearer days earlier in the week, while modest cool-air advection following Thursday’s rain keeps daytime maxima in check. Typical September variability in the North China Plain, where afternoon temperatures often hinge on exact cloud timing and boundary-layer mixing, explains why market-implied probabilities cluster tightly around 23–26 °C. Official maximum-temperature readings from Beijing stations will resolve the market once the day ends.
