Latest weather model ensembles from ECMWF and GFS, updated within the past 24 hours, drive trader consensus toward a Shanghai high temperature of 14-16°C on March 21, with implied probabilities tightly clustered as frontal systems exit the region post-cold snap. These global models show a mean forecast around 15°C, differentiated by slight variances in boundary layer mixing and residual cloud cover—ECMWF leans cooler at 14°C due to persistent stratus, while GFS implies 16°C amid emerging southerly flow. Historical March 21 averages hover at 13-15°C, but urban heat island effects in Shanghai amplify nighttime recovery, narrowing uncertainty; traders eye hourly updates from the China Meteorological Administration for resolution-defining peaks.

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.
