Trader consensus has locked in 25°C as the highest temperature in Shanghai on May 6 at virtually 100% implied probability, driven by intraday observations at Shanghai Pudong International Airport—the market's official resolving station—peaking at 25°C under partly cloudy conditions with southerly winds at 14 km/h and 40% humidity capping solar heating. China Meteorological Administration forecasts and international model ensembles (ECMWF, GFS) converge on this outcome, aligning with early May climatology where daily highs average 24-26°C amid typical spring frontal systems. Realistic challenges include unexpected clearing skies enabling late-afternoon radiative warming to 26°C or minor measurement revisions, though current trajectories and diurnal patterns make higher readings unlikely; end-of-day airport data will finalize resolution.

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.
