Recent meteorological forecasts for Shanghai on September 21 indicate a high near 28–29°C under partly cloudy skies with light northerly winds, aligning with the market's leading implied probabilities for those exact outcomes. Late-summer atmospheric conditions in eastern China, including moderate humidity and stable high pressure, support typical seasonal maxima without significant frontal systems or enhanced solar heating. Model consensus from sources like the GFS shows limited spread around these values, though small variations in cloud cover or wind could shift the final reading by 1°C. Historical September averages for the region hover near 28°C, providing context for the tight clustering around the two frontrunners ahead of official observations.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 21 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Recent meteorological forecasts for Shanghai on September 21 indicate a high near 28–29°C under partly cloudy skies with light northerly winds, aligning with the market's leading implied probabilities for those exact outcomes.
