Current observational data and forecast models indicate Chongqing's overnight low on October 13 will reach 20°C amid persistent cloud cover, high humidity near 90%, and light winds that limit radiative cooling. Multiple sources, including local meteorological reports and numerical guidance, show temperatures stabilizing in the 20–22°C range through the night under these subtropical autumn conditions, consistent with historical mid-October baselines for the region. Trader consensus at 100% reflects this strong alignment in real-time measurements and model runs. A rapid shift to clear skies or an unanticipated northerly air mass could allow greater cooling and alter the exact low, though current pressure patterns and steering make such changes improbable before resolution.
