Recent model guidance from major ensembles shows Shanghai's May 20 overnight low likely settling between 20 °C and 23 °C, explaining the tight clustering of trader probabilities around those three outcomes. In the Yangtze River Delta's transitional spring regime, nocturnal radiative cooling is highly sensitive to subtle shifts in low-level wind speed, boundary-layer moisture, and cloud cover; even modest increases in southeasterly flow or dew-point depression can raise the minimum by 1–2 °C. Historical China Meteorological Administration records place mid-May lows near 17 °C on average, yet recent warm anomalies have lifted the distribution, keeping the 22 °C bin narrowly favored while leaving genuine resolution risk among the adjacent integers until the final 48-hour forecast updates.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 20 May '26.
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.Recent model guidance from major ensembles shows Shanghai's May 20 overnight low likely settling between 20 °C and 23 °C, explaining the tight clustering of trader probabilities around those three outcomes.
