Current forecasts from Chinese meteorological sources and global models point to a 26°C high in Qingdao on September 17 under mostly cloudy conditions with southeast winds, reflecting strong marine moderation from the Yellow Sea that typically caps mid-September maxima near 25–27°C. Trader consensus favoring 27–28°C outcomes stems from the preceding day's 29°C reading and inherent short-range model spread on cloud cover and boundary-layer mixing, which can shift peak temperatures by 1–2°C. Historical climatology shows early-September highs averaging 26–27°C with low variability due to oceanic influence, while resolution hinges on updated runs from the China Meteorological Administration and any last-minute shifts in steering flow or insolation.

The resolution source for this market will be information from NOAA, specifically the highest 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.
