Forecast models from GFS and ECMWF show Shanghai under mostly cloudy skies with light northeasterly winds and a modest chance of brief showers on September 11, which typically caps daytime heating near 27–30°C. Recent runs indicate afternoon highs clustered around 28–29°C, with 28°C slightly favored due to persistent cloud cover reducing solar insolation and higher humidity near 70% limiting further warming. Historical September baselines average 27°C, but variable steering patterns and any early clearing could push readings to 30°C. The near-even market odds between 28°C and 29°C reflect this narrow uncertainty range ahead of final observational data.

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.
