Current forecasts from multiple meteorological sources indicate Beijing's overnight low on October 3, 2026, will likely settle near 11–12°C under partly cloudy skies and light winds, aligning with the historical average low of 12°C for the date and typical early-autumn radiative cooling after daytime highs of 22–24°C. Model consensus shows no strong cold-air advection or significant cloud cover to alter the minimum substantially, though minor variations in wind speed or timing of any clearing could shift the exact reading by 1°C. Trader sentiment reflects this narrow band of uncertainty around the seasonal baseline, with lower-probability outcomes tied to rarer deviations such as enhanced nocturnal cooling under clear, calm conditions or slight warming from increased mixing. Updated short-range model runs in the next 24–48 hours will refine the precise threshold.
