Trader consensus around 23–24°C for Chongqing’s September 22 maximum reflects short-range model spread in the 48-hour window, with ensembles from the China Meteorological Administration and ECMWF showing daytime highs clustered near seasonal norms for late September. Persistent subtropical high pressure and weak southerly flow are limiting strong advection, while variable low-level moisture and potential afternoon convection introduce uncertainty in peak readings. Historical September maxima average near 25°C, but recent cooler anomalies tied to an early autumn trough have pulled probabilities downward. Key resolution hinges on official station data, with model updates through September 21 likely to narrow the tight 22–24°C band.

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.
