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 21 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Shanghai Pudong International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official observations from Shanghai Pudong International Airport—the market's resolution source on Weather Underground—confirm a daily maximum temperature of 16°C on April 21, 2026, under persistent overcast skies, light rain, and northerly winds at 3–15 mph that suppressed daytime heating. Morning readings near 14°C aligned with China Meteorological Administration guidance and forecast model consensus capping peaks amid a cool air mass. This positions trader consensus at near-certainty for 16°C, reflecting verified hourly data through late afternoon. Realistic challenges include an improbable late-day clearing boosting solar insolation to 17°C before sunset or post-finalization data revisions, though current station records show no such exceedance. Final ratification expected within 24 hours.
