Recent ensemble guidance from the ECMWF and GFS models places Shanghai’s May 18 maximum in a narrow 26–27 °C band, with the slight market edge to 27 °C reflecting marginally stronger insolation under partly cloudy skies. Mid-May conditions remain transitional between spring and pre-monsoon regimes, so daytime warming depends on the timing of any East China Sea breeze and the extent of residual cloud cover that can suppress peak temperatures by 1–2 °C. Historical climatology for the date shows daily highs clustered between 22 °C and 27 °C, confirming that a single degree separates the two leading outcomes and leaves room for modest model spread or small changes in boundary-layer moisture before resolution.

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.
