Recent forecasts for Chengdu indicate a low near 18–20°C on September 21 amid ongoing Huaxi Autumn Rain, which sustains extensive cloud cover and moderate humidity that limits both daytime warming and nocturnal radiative cooling. This pattern, typical of the Sichuan Basin in mid-to-late September, produces a narrow diurnal temperature range with historical September lows averaging 18–19°C. Current model consensus from regional guidance shows stable steering patterns and no strong cold-air intrusion or clear-sky heating that would push extremes below 16°C or above 26°C. Traders appear to weigh residual uncertainty in the final 48-hour forecast updates against the high probability of continued overcast conditions.

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.
