Recent forecast models from sources including the China Meteorological Administration and international ensembles indicate a minimum temperature in Qingdao on October 9 likely between 16–19°C, driven by clear to partly cloudy skies, light southerly winds of 2–5 m/s, and moderate humidity limiting radiative cooling. Coastal marine influence and urban heat effects add uncertainty to the exact overnight low, with some runs showing potential for brief dips near 15°C under clearer conditions while others hold above 18°C. This narrow range near historical October averages explains the closely matched market-implied odds, as small shifts in cloud cover or wind speed could tip the daily minimum across key thresholds before resolution.
