Recent observational data and forecast model consensus from sources including the China Meteorological Administration point to a daily high of exactly 27°C in Chongqing on September 13, underpinning the market's near-certain implied probability. Overcast skies, light variable winds, and moderate humidity around 60-70% have limited further warming while preventing significant cooling, aligning with typical mid-September conditions for the region where average highs hover near 26-29°C. Official station reports through the afternoon have consistently registered this peak without upward revisions. Only a late-day measurement error, post-closure data adjustment, or highly localized microclimate anomaly at the primary reporting site could realistically alter the outcome before final verification.

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=zuck
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.
