Trader consensus on Polymarket reflects razor-thin forecast model agreement for Shanghai's May 16 minimum temperature, with GFS and ECMWF ensembles clustering around 19°C amid partly cloudy overnight conditions and mild southerly winds that limit radiative cooling. Leading outcomes at 33.5% for 19°C, 32.5% for 18°C, and 30% for 20°C capture this uncertainty, as slight variations in cloud cover evolution or urban heat island amplification from Shanghai Pudong's dense surroundings could tip the official reading by 1–2°C. High humidity near 80% further moderates drops below 18°C, diverging from May climatological lows of 16–17°C. Watch evening soundings and dawn observations for shifts ahead of resolution based on China Meteorological Administration data.

The resolution source for this market will be information from Wunderground, specifically the lowest 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.
