Forecast models from the ECMWF and GFS ensembles currently converge on a narrow 26–27°C range for Shanghai’s highest temperature on May 17, driving the market’s strong tilt toward those two outcomes. Mid-May conditions in the region typically feature moderating spring warmth under variable subtropical ridge influence, with ensemble spreads tightening around these values after recent model runs incorporated updated satellite and surface observations. Traders assign the highest implied probability to exactly 26°C, reflecting slightly greater consensus for that threshold amid modest uncertainty in boundary-layer moisture and daytime heating rates. Official resolution will depend on the peak reading recorded at Shanghai Pudong International Airport, with any last-hour convective development or clearer skies able to nudge the maximum by 1°C.

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.
