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 7 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 forecasts for Shanghai on September 7 indicate a high near 29–30°C amid light rain transitioning to partly cloudy skies and northerly winds of 5–8 m/s, creating tight market-implied odds between those two outcomes. Model consensus from sources like ECMWF and GFS shows modest daytime heating under variable cloud cover, with dew points around 18–20°C limiting further warming, while historical September baselines for the region average highs near 29°C. Minor differences in predicted cloud thickness or brief clearing windows could determine whether maximum readings reach the 30°C threshold or remain at 29°C, with updated model runs and official China Meteorological Administration briefings expected to refine these details ahead of resolution.
