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 20 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.

"context_description": "Trader consensus on Polymarket has locked in a 100% implied probability for Shanghai's highest temperature reaching exactly 19°C on April 20, 2026, driven by official observations from Shanghai Pudong International Airport and Xujiahui stations recording peak readings of 19°C mid-afternoon amid persistent cloud cover and northerly winds around 13 mph that capped daytime heating. Latest ECMWF and GFS ensemble forecasts, aligned with China Meteorological Administration guidance, projected highs tightly clustered at 19–20°C, matching historical April averages near 19°C under similar overcast conditions with moderate UV index. Current evening temperatures have dropped to 17°C with increasing cloudiness, minimizing further warming potential before sunset. Realistic challenges would require sudden clearing skies and stronger solar insolation, though barometric stability at 30 inHg and 25% precipitation risk make this improbable. Official daily summaries expected shortly will confirm resolution.",
