**Trader consensus on an 11°C low for Qingdao on October 13 reflects converging official forecasts and early observational data showing overnight temperatures bottoming at that threshold.** Northerly winds of 4–5 Beaufort, clearing skies after daytime highs near 21–23°C, and radiational cooling under light winds have produced the expected minimum, consistent with China Meteorological Administration guidance and international model runs. Historical October climatology for the region supports lows in the low teens Celsius, and current conditions align precisely with the 11°C mark without deviation in verified station readings. The near-certain market pricing leaves little room for alternatives unless final post-midnight observations at primary stations register a marginal shift due to microclimate effects or instrument calibration.
