Current forecasts from multiple meteorological sources indicate a minimum temperature of 23°C in Shanghai on September 23, 2026, under mostly cloudy skies with light easterly winds and high humidity around 70-80%. This aligns with the late-September seasonal transition in the region, where average lows typically range from 22-25°C amid moderating monsoon influences and stable atmospheric conditions. Trader consensus at 98.5% for 23°C reflects strong model agreement on these parameters, though minor shifts could arise from updated regional observations or localized cloud dynamics altering overnight radiative cooling. Resolution hinges on official verified minimum readings rather than preliminary estimates.

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.Current forecasts from multiple meteorological sources indicate a minimum temperature of 23°C in Shanghai on September 23, 2026, under mostly cloudy skies with light easterly winds and high humidity around 70-80%.
