Current forecasts for Chengdu on September 21 point to overnight lows near 20–22°C amid persistent cloud cover, light southerly winds under 5 km/h, and high humidity exceeding 80% in the Sichuan Basin. These conditions limit radiative cooling overnight while suppressing stronger temperature drops. Model consensus from sources like ECMWF and GFS shows minimal variability, yet subtle differences in cloud thickness, boundary-layer mixing, or minor moisture advection could shift the minimum by 1–2°C. Trader odds clustered around 16–21°C reflect this narrow uncertainty band, with historical September baselines near 19°C providing context. Final resolution hinges on official station readings after midnight local time.

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.
