**Forecast models indicate Beijing's overnight low on October 13 will likely fall between 6–10°C under clear skies following a cold front.** Northwest winds strengthening to 3–4 on the Beaufort scale, with gusts to 6–7, are advecting drier continental air after scattered light rain on October 12. This setup promotes strong radiative cooling overnight, with dew points dropping into the single digits and minimal cloud cover. Official guidance from sources such as the China Meteorological Administration and international models (GFS) shows highs near 20–22°C and lows clustered around 8–9°C, though slight variations in wind timing or residual moisture could shift the minimum by 1–2°C. Historical October minima in Beijing average near 9°C, placing current conditions close to seasonal norms. The tightly matched market prices around 8–11°C reflect this narrow uncertainty band ahead of final observations.
