Forecasts from sources including the China Meteorological Administration and international models indicate mild overnight conditions for Qingdao on September 29, with lows expected near 21–22°C under southerly winds of 3–4 levels and partly cloudy skies that limit radiational cooling. This aligns with late-September climatology for the coastal Shandong region, where warm advection from the Yellow Sea typically prevents sharp drops before a northerly shift arrives around September 30. Recent observations show daytime highs near 23–25°C with dew points supporting humidity around 60–70%, reducing the chance of rapid nighttime cooling. Market-implied odds favoring 15°C or below as the top outcome reflect trader assessment of potential model variability or faster frontal passage, while probabilities clustered around 16–17°C capture the range of forecast uncertainty ahead of final observational data.
