Trader sentiment clusters tightly around 16°C (29.5%) and 17°C (28.0%) as highest temperatures for Shanghai on March 25, driven by converging global weather model ensembles from ECMWF and GFS showing daytime highs in the mid-teens Celsius amid a mild spring front. Recent developments, including a slight cooldown from upstream cold air advection over eastern China observed in CMA satellite data, differentiate these from cooler 15°C (24.0%) odds, while capping warmer 18°C+ at lower probabilities due to persistent cloud cover suppressing solar insolation. Historical March norms (average high 14-16°C at Xujiahui station) and urban heat island effects add modest upside variance, with final resolution hinging on 00Z model updates and low-level winds.

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.
