**Forecast models and official guidance from Chinese meteorological sources indicate a minimum temperature near 22°C for Qingdao on September 17 under mostly cloudy conditions with southeast winds of 3–4 levels.** This setup limits radiational cooling compared to clear skies, while moderate humidity and light possible drizzle in some runs support the clustered market odds favoring 19–21°C outcomes. Trader consensus reflects uncertainty in the precise overnight low, as small variations in cloud thickness or wind mixing can shift the minimum by 1–2°C. Historical September averages around 18°C provide baseline context, but current warm advection keeps values elevated. Updated model runs and local observations ahead of the overnight period represent the key upcoming data points that could refine probabilities.

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.
