Current forecast consensus from the China Meteorological Administration, ECMWF, and GFS models places Shanghai’s May 18 peak near 26–28 °C under a persistent subtropical high-pressure ridge, with light easterly winds and 60–70 % relative humidity limiting daytime heating and producing the market’s highest implied probability for exactly 27 °C. Ensemble guidance shows limited spread around this range, consistent with mid-May climatology where daily maxima typically average 24–26 °C but can reach the upper 20s when subsidence strengthens. Traders are weighting the latest model runs most heavily, as afternoon observations tomorrow will resolve the contract against official station data.

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 18 May '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.Current forecast consensus from the China Meteorological Administration, ECMWF, and GFS models places Shanghai’s May 18 peak near 26–28 °C under a persistent subtropical high-pressure ridge, with light easterly winds and 60–70 % relative humidity limiting daytime heating and producing the market’s highest implied probability for exactly 27 °C.
