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 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.

"context_description": "Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 22°C in Shanghai on April 28, driven by real-time observations from the Xujiahui observatory and Shanghai Pudong International Airport station, where daytime peaks aligned precisely with this mark under overcast skies and scattered light rain. This reflects a sharp cooldown from April 26-27 highs of 26-28°C at Xujiahui, triggered by a frontal passage ushering northerly winds and precipitation, as forecasted by China Meteorological Administration models and corroborated by GFS/ECMWF ensembles showing tight 21-23°C spreads. April's +2°C above-normal trend persists, but cloud-induced suppression of solar heating caps upside. Realistic challenges—such as unexpected afternoon clearing—appear negligible given persistent cloudy conditions and advancing evening diurnal cooling, with final Shanghai Meteorological Bureau data expected to seal resolution.",
