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 4 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 and model forecasts for Shanghai on September 4 indicate a daily maximum of 30–31°C under partly cloudy to overcast skies with scattered showers, driven by persistent northeast monsoon flow and residual moisture from regional systems. This aligns with early-September climatology in the subtropical zone, where average highs reach 28–30°C amid moderating summer heat and increasing variability from frontal passages. Multiple numerical weather prediction outputs show tight consensus on peak temperatures in this narrow range, with limited potential for stronger diurnal heating due to cloud cover and winds of 10–15 km/h. Trader consensus reflected in the market therefore centers on these values as the most probable outcomes given current observational trends and short-range model agreement.
