**Trader consensus at 100% for a 17°C low in Chengdu on October 7, 2026, rests on consistent forecasts from official Chinese meteorological sources showing a minimum temperature of 17°C under mostly cloudy to partly cloudy skies.** Recent model runs and early observational data align on this value, reflecting typical autumn radiative cooling under light winds and high humidity that limits overnight temperature drops in the Sichuan Basin. Historical analogs for early October in the region show similar overnight lows near 15–18°C during comparable stable patterns. While official minimum readings from primary stations are expected to confirm 17°C, minor deviations could arise from localized urban heat effects, slight forecast shifts in cloud cover, or station-specific measurement timing before final resolution.
