Recent official forecasts from agencies and models indicate a high near 29–30°C for Shanghai on September 12, driven by partly cloudy skies, light northeast winds around 6–8 mph, and low precipitation chances under subtropical early-autumn conditions. Current observations show morning temperatures in the mid-20s°C with rising values through midday, while humidity near 60–75% and minimal cloud interference support modest warming. The tight market split between 28°C and 29°C reflects minor model differences in peak timing, urban heat-island effects, and exact cloud cover evolution, with traders weighting real-time station data from the China Meteorological Administration against historical September baselines around 28–30°C. Updated afternoon observations and final NWP runs will likely resolve the narrow spread.

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 12 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 official forecasts from agencies and models indicate a high near 29–30°C for Shanghai on September 12, driven by partly cloudy skies, light northeast winds around 6–8 mph, and low precipitation chances under subtropical early-autumn conditions.
