Trader consensus on Polymarket closely splits between 20°C (35.5%) and 21°C (32.0%) for Shanghai's highest temperature on April 17, reflecting tight convergence in major forecast models like ECMWF, GFS, and China Meteorological Administration ensembles, which project daytime highs of 20–21°C under partly cloudy skies with 20–25% shower risk capping intense heating. Recent recovery from an early-April cold snap—where highs dipped to 17–19°C on April 12–16 due to northerly air masses—has shifted odds upward as southerly flows introduce milder, humid air over the Yangtze Delta, aligning with mid-April climatological normals near 19–20°C at Xujiahui station. Key differentiators include model disagreements on afternoon cloud clearance and diurnal temperature range; fuller sun could push to 21°C, while persistent overcast favors 19–20°C. Updated model runs overnight and official observations resolve the market.

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 17 Apr '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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket closely splits between 20°C (35.5%) and 21°C (32.0%) for Shanghai's highest temperature on April 17, reflecting tight convergence in major forecast models like ECMWF, GFS, and China Meteorological Administration ensembles, which project daytime highs of 20–21°C under partly cloudy skies with 20–25% shower risk capping intense heating. Recent recovery from an early-April cold snap—where highs dipped to 17–19°C on April 12–16 due to northerly air masses—has shifted odds upward as southerly flows introduce milder, humid air over the Yangtze Delta, aligning with mid-April climatological normals near 19–20°C at Xujiahui station. Key differentiators include model disagreements on afternoon cloud clearance and diurnal temperature range; fuller sun could push to 21°C, while persistent overcast favors 19–20°C. Updated model runs overnight and official observations resolve the market.
