This market will resolve to the temperature range that contains the highest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 31 May '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Trader consensus has converged on a 28°C high for Shanghai on May 31 due to the latest consensus from numerical weather prediction models, which project peak afternoon temperatures aligning precisely with this threshold under prevailing subtropical high-pressure conditions and moderate southerly flow. Official monitoring from agencies such as the China Meteorological Administration indicates stable atmospheric profiles with limited diurnal heating potential, consistent with late-May climatology where daily maxima typically range 25–30°C. Recent satellite and surface observations confirm minimal deviation from these guidance runs. A sudden shift in cloud cover, localized convective activity, or revised model initialization could alter the outcome, though current data show low uncertainty in the near-term forecast.
