Forecast models from sources including GFS and agency outlooks point to clear skies and northwest winds over Beijing on October 13, supporting a daytime high near 21–22°C after a cooler period earlier in the month. Dry air advection and minimal cloud cover limit warming potential while preventing significant cooling, aligning with climatological norms around 20°C for mid-October. Recent model runs have converged on this range without notable shifts, driving the strong market weighting toward 22°C and 21°C outcomes. Traders appear to weigh the low probability of outliers such as 23°C or higher, given the stable high-pressure pattern and absence of southerly flow that could elevate temperatures. Updated guidance through the day will refine resolution criteria tied to official maximum readings.
