Recent meteorological forecasts from models including GFS indicate a high near 29°C in Shanghai on September 14 under partly cloudy skies with moderate northeasterly winds and low precipitation chances. This consensus, with highs projected between 28–30°C across sources, underpins the market-implied 58.5% probability for 29°C as the leading outcome, followed by 28°C. Typical early-September climatology in the region features daytime maxima around 27°C, but current steering patterns and surface conditions favor slightly elevated readings without significant heat advection or clear-sky intensification. Updated model runs and official observations on the day will determine final resolution.

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.
