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 on Polymarket assigns a 96.5% implied probability to a highest temperature of 21°C in Shanghai today, backed by the China Meteorological Administration's (CMA) latest forecast guidance showing a daytime maximum near 21°C under overcast skies and light southeasterly winds below 12 km/h. Early morning observations at the official Xujiahui station reflect steady warming from the mid-teens Celsius, aligning with hourly model outputs from sources like weather.com peaking at around 21°C amid mild southerly flow. This positioning exceeds typical late-March averages of 16-18°C due to a warmer-than-normal air mass. Realistic challenges include increased cloud cover capping the peak at 20°C or below, or unexpected clearing allowing 22°C+; afternoon station readings will provide final confirmation as the market nears resolution.
