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 28 Mar '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.Trader consensus overwhelmingly favors a highest temperature of 21°C in Shanghai today, backed by hourly observations from the official Xujiahui Observatory station, where mid-morning readings peaked at 21°C (70°F) amid partly cloudy skies and light southerly winds that limited solar insolation and convective mixing. This aligns precisely with the China Meteorological Administration's (CMA) latest forecast ensembles and ECMWF model consensus projecting daytime maxima of 20–21°C, consistent with late-March warm fronts elevating temperatures above the 12–13°C monthly average. With the day advancing and cloud cover suppressing further warming, realistic challenges would require unexpected clearing for enhanced shortwave radiation or amplified urban heat island effects to nudge peaks toward 22°C; the CMA's final daily summary, due this evening, will confirm resolution.
