Updated ensemble forecasts from the GFS and ECMWF models indicate overnight lows in Shanghai stabilizing near 19–21°C on May 20, driven by persistent southerly flow, elevated dew points near 18°C, and limited radiative cooling under partly cloudy skies. This aligns with Shanghai’s May climatology, where average minima rise from 16–17°C early in the month to 18–20°C by mid-to-late May under neutral ENSO conditions. Recent surface observations from Pudong International Airport show a warming trend since mid-month, with urban heat-island effects further moderating temperature drops. Trader consensus assigns the highest implied probability to 15°C or below while spreading significant weight across the 19–22°C range, reflecting genuine uncertainty from variable cloud cover and potential frontal passages. New model runs and China Meteorological Administration guidance expected within 48 hours will refine the resolution threshold.

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.
