Recent forecasts from Chinese meteorological services project an overnight low near 23°C in Shanghai on September 23 under mostly cloudy to overcast skies with light easterly winds, which limit radiative cooling and maintain higher minimum temperatures compared to clearer conditions. This aligns with late-September climatology, where average lows hover around 20–22°C amid the transition from summer monsoon influences to cooler autumn patterns. Trader sentiment clusters around 23–24°C outcomes because ensemble models show limited variability in boundary-layer moisture and wind speeds, though shifts in cloud thickness or subtle pressure gradients could allow modest deviations. Historical data indicate that prolonged clear nights occasionally produce lows several degrees cooler, sustaining modest probability on the 18°C-or-below bin despite the current consensus.

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=zspd
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.
