Current forecasts for Chengdu on September 20 show overnight lows stabilizing near 20–22°C amid persistent cloud cover, high humidity near 85–90%, and light winds, which limit radiative cooling overnight in the Sichuan basin. Official model consensus from sources tracking the region points to a daily minimum around 21°C, aligning with recent days’ patterns of 20–21°C lows under similar overcast conditions. Traders weigh the slim chance of partial clearing or localized variations that could push readings to 19°C or below against the stabilizing effect of moisture-trapping clouds and typical September climatology, where basin inversions rarely allow sharper drops. New observational data or updated model runs later in the day could refine these thresholds.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Chengdu Shuangliu International Airport Station in degrees Celsius on 20 Sep '26.
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.Current forecasts for Chengdu on September 20 show overnight lows stabilizing near 20–22°C amid persistent cloud cover, high humidity near 85–90%, and light winds, which limit radiative cooling overnight in the Sichuan basin.
