Trader consensus assigns a 50% implied probability to a lowest temperature of 16°C or below in Qingdao on September 18, reflecting model guidance for cooler maritime air and possible frontal passage that could suppress overnight minima below the seasonal average of 18–20°C. Ensemble forecasts show notable spread, with some runs indicating persistent onshore flow supporting 17–19°C lows while others allow brief warming. The 39.5% chance attached to 26°C or higher captures upside risk from delayed seasonal cooling or subtropical ridge influence. Updated CMA and global model runs expected in the next 12–24 hours will likely narrow the range ahead of resolution.

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.
