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 27 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.Traders show unanimous 100% implied probability for a Shanghai high temperature of exactly 19°C on March 27, anchored by verified observations from the Shanghai Meteorological Service's official stations, including Pudong International Airport and Xujiahui Observatory, which recorded maximums peaking at this level amid cool, cloudy spring conditions with light northerly winds suppressing warmer air advection. Pre-event forecasts from ECMWF and GFS models had converged on upper-teen Celsius highs, consistent with March climatology where average Shanghai peaks hover around 14–18°C, further bolstered by regional cold fronts. Scenarios challenging this near-certainty would require rare post hoc data revisions from authorities, such as sensor recalibrations revealing overlooked peaks, though historical precedents for such adjustments in daily highs are minimal.
