Forecast models and real-time observations indicate Chongqing's September 3 high will peak near 33–34°C under mostly clear skies, light northeasterly winds around 5–10 km/h, and moderate humidity near 40%, favoring strong solar insolation with minimal cloud interference or evaporative cooling. The city's location in the Sichuan Basin promotes subsidence warming and traps heat through limited ventilation, while the urban heat island effect amplifies afternoon maxima by 1–2°C relative to rural surroundings. Slight differences between 33°C and 34°C outcomes hinge on precise timing of the daily peak, station siting variations, and minor model adjustments to boundary-layer mixing. Official China Meteorological Administration data and nearby station readings will resolve the market, with historical September averages around 28–32°C providing context for the current elevated conditions.

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.
