Recent official forecasts from the Chengdu Meteorological Office and global models indicate a gradual cooling trend through mid-October, with October 17 expected to feature mostly cloudy skies, scattered light rain, and a daily low near 15–18°C amid light northerly winds. This positions the overnight minimum close to the 15°C threshold, where enhanced cloud cover and precipitation limit radiative cooling while variable steering patterns introduce modest uncertainty in exact timing. Trader sentiment remains balanced near 50% on the 15°C-or-below and 25°C-or-higher brackets because models show slight divergence on boundary-layer moisture and wind strength, with historical October lows in Chengdu averaging around 15°C providing context. Updated high-resolution runs from the China Meteorological Administration and real-time station data on the 17th will refine resolution criteria for the daily minimum.
