Recent model runs from sources including ECMWF and GFS indicate Chengdu highs on September 21 will likely reach 26–28°C under mostly cloudy skies, light southerly winds, and elevated humidity that curbs daytime heating. This aligns with the late-September cooling trend from peak summer values near 30°C, matching historical September averages of 26–27°C. Market odds cluster tightly at 27–30°C because small differences in cloud cover duration, any brief clearing, or minor steering pattern shifts can add or subtract 1–2°C at peak afternoon hours. Official China Meteorological Administration updates and next model cycles will refine these variables ahead of resolution.

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=zuuu
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.
