Recent forecast models indicate moderating daytime highs in Chongqing driven by seasonal decline in solar insolation and increased cloud cover typical of mid-September transition. The Sichuan Basin's topography often traps cooler, humid air masses while frontal passages or light precipitation suppress peak temperatures below the month's early-September average near 29°C. Trader consensus around 20–23°C aligns with historical late-month cooling patterns and current ensemble guidance showing limited afternoon heating under overcast conditions. Key uncertainties include exact timing of any rain events and local wind patterns that could alter the daily maximum by 1–2°C before 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=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.
