Recent forecasts from Chinese meteorological sources and international models converge on a September 12 high near 30°C in Chongqing under mostly cloudy conditions, with limited solar heating and light northerly winds limiting further warming. Current observations show temperatures in the mid-20s amid overcast skies and scattered showers, setting up modest daytime recovery as the system shifts. Historical September maxima average 27–28°C, providing baseline context, while short-term model runs show minor spread between 28–31°C depending on exact cloud timing and boundary-layer mixing. Trader emphasis on 29°C reflects this narrow forecast envelope and the low probability of outliers given stable steering patterns ahead of the weekend.

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.
