Forecast models from sources including GFS runs and regional services indicate a high near 29°C in Shanghai on September 12 under northeast winds of 8–13 km/h, partly cloudy to clear skies, and minimal precipitation risk. This setup supports moderate daytime heating with dew points in the mid-teens Celsius and relative humidity dropping below 60% during peak hours, consistent with early-autumn conditions slightly above the long-term September maximum average of 27°C. Current observations on September 11 show stable high pressure near 1020 hPa with light northeasterly flow, limiting cloud buildup and favoring the market-implied clustering around 28–29°C. Minor model spread on exact cloud timing keeps 30°C a lower-probability outcome while rendering extremes below 27°C or above 31°C unlikely absent rapid changes in steering patterns. Updated model guidance overnight will refine the final peak.

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.
