Latest forecasts from the China Meteorological Administration and supporting international models like ECMWF project Shanghai's lowest temperature on April 30 at exactly 10°C, driving trader consensus to near-certainty with 100% implied probability on that outcome. Current observations confirm early-morning readings around 9–11°C under clear skies and light winds, consistent with late-April climatology where overnight lows typically range 10–13°C amid mild southerly flows and no active cold fronts. High-confidence model ensembles show minimal spread, with radiative cooling limited by urban heat island effects in the megacity. Realistic challenges include unexpectedly prolonged clear conditions enhancing surface cooling to dip below 9°C briefly before dawn, though official station data (e.g., Pudong Airport) will finalize resolution by evening.

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 30 Apr '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.
