Trader consensus heavily favors a 21°C minimum in Chengdu on September 5, driven by official station observations confirming that threshold under persistent subtropical high pressure and clear to partly cloudy conditions that limited nocturnal cooling. Model runs from regional meteorological centers aligned closely with historical September baselines for the Sichuan basin, where radiative cooling at night typically produces lows in the low 20s amid moderate humidity and light winds. The near-certainty reflects verified measurements rather than forecasts, with minimal scope for revision absent station data adjustments. Only unexpected microclimate effects or reporting discrepancies could alter resolution, though atmospheric stability made such shifts improbable.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
