The market's overwhelming 98% consensus on 23°C as Shanghai's lowest temperature on September 23 reflects consistent official forecasts and observations from meteorological agencies showing overnight lows stabilizing at that level under overcast skies, light easterly winds under 3 levels, and typical late-September humidity patterns that limit radiative cooling. These conditions align with historical baselines for the period, where cloud cover and moderate winds prevent drops below the 23°C mark observed in recent days. Final verified minimum readings from ground stations will resolve the market, though scenarios like unexpected clear skies enhancing nighttime cooling or unforecasted cold air advection could theoretically shift outcomes, current model consensus leaves little room for such changes.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 23 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=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.The market's overwhelming 98% consensus on 23°C as Shanghai's lowest temperature on September 23 reflects consistent official forecasts and observations from meteorological agencies showing overnight lows stabilizing at that level under overcast skies, light easterly winds under 3 levels, and typical late-September humidity patterns that limit radiative cooling.
