Strong model consensus from sources including the China Meteorological Administration and international forecasts positions an 18°C overnight low as the dominant outcome for Chengdu on October 13, 2026, with partly cloudy skies, light northerly winds, and minimal radiative cooling under a stable autumn pattern in the Sichuan Basin. This aligns with observed highs near 28°C earlier in the day and typical October baselines around 15–18°C. Trader sentiment reflects high confidence in this range, as ensemble predictions show limited spread. A shift to heavier cloud cover or an unforecast frontal influence could push the minimum toward 17°C or below, though current observational data and short-term model runs make such deviations unlikely before resolution.
