Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System models show Shanghai’s May 17 maximum temperature tightly clustered between 26°C and 27°C, driving the market’s near-even split at 42.5% and 37.5% implied probability. Stable atmospheric steering patterns, limited moisture advection, and modest cloud cover have narrowed model spread, with the slight preference for 26°C reflecting greater agreement across higher-resolution runs. Historical mid-May climatology near 25–26°C at the Xujiahui station provides context, while urban heat-island amplification and official China Meteorological Administration thresholds add precision to the resolution criteria. Updated model guidance expected within the next 12 hours could further refine these probabilities ahead of the official daily high measurement.

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.
