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 27 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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 numerical weather model consensus, including outputs aligned with GFS and ECMWF guidance, positions a warm, humid subtropical air mass over Shanghai with northeast winds of 10–15 mph, partial cloud cover, and only light or scattered showers expected on August 27. These conditions support afternoon highs near the seasonal late-August average of 31–32 °C while limiting strong surface heating or rapid cooling. Current observations show daily maxima in the low 30s °C through August 25, with no approaching cold front or significant moisture surge to alter the pattern. Trader sentiment, reflected in the 53 % implied probability for 32 °C and 30 % for 31 °C, aligns with this stable forecast envelope, where modest model spread around precipitation timing keeps outcomes tightly clustered between 31–33 °C.
