Recent forecast model consensus from global and regional ensembles, including those informing China Meteorological Administration guidance, centers the overnight minimum in Chengdu near 23°C under partly cloudy skies with light winds and moderate humidity. This aligns with early September climatology for the Sichuan basin, where diurnal ranges narrow amid transitioning monsoon patterns and average lows of 21–24°C. Trader positioning at 67% implied probability for exactly 23°C reflects updated runs showing slightly cooler boundary-layer conditions than prior outlooks, while secondary support for 22°C incorporates model spread and potential for localized cooling. Official station observations through the night will resolve the market, with resolution hinging on precise minimum readings before sunrise.

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.
