Current ensemble forecasts from the China Meteorological Administration, ECMWF, and GFS models indicate a peak temperature in Shanghai on May 18 near 26–28°C, with the market placing the highest implied probability on 27°C. A persistent subtropical high-pressure ridge combined with light easterly winds is limiting warm-air advection, while relative humidity near 60–70% moderates daytime heating under partly cloudy skies. This setup aligns with mid-May climatology, when average highs typically range from 25–26°C, yet minor variations in cloud cover, wind speed, or local urban heat effects create genuine uncertainty that keeps the top three outcomes within roughly ten percentage points. Updated model runs and official observations tomorrow morning will determine the precise maximum 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.
