Current forecasts from multiple models indicate a low near 18–20°C for Qingdao on September 11, driven by moderate southerly flow, increasing cloud cover, and limited overnight radiative cooling under a stable air mass. The near-even market split between 22°C or higher and 12°C or below reflects uncertainty in the precise timing of any weak frontal boundary or wind shift that could alter minimum temperatures by several degrees. Key variables include local sea-breeze effects along the Yellow Sea coast, dew-point depression, and potential model divergence in boundary-layer mixing; updated runs from agencies such as the China Meteorological Administration will refine these thresholds ahead of the observation window.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zsqd
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
