Traders have converged on 27°C as the implied outcome for Qingdao’s highest temperature on September 10 due to consistent forecasts from regional models and the China Meteorological Administration showing a daytime peak near that level under partly cloudy skies, northerly winds of 3–4 m/s, and low humidity around 40–60%. Observational data through the afternoon aligned with these projections, with surface readings climbing to the mid-20s Celsius before stabilizing, consistent with September climatology for the coastal Shandong station where September daily maxima average near 26°C. The near-100% market pricing reflects high confidence in the forecast consensus, though modest uncertainty remains around station-specific measurement timing or localized sea-breeze effects that could nudge the official high slightly higher or lower before midnight close.

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.
