Official observations from Shanghai's Xujiahui observatory—the authoritative station for citywide meteorological records—confirm a daytime high temperature of 21°C on April 18, 2026, under mostly sunny skies with light winds and moderate humidity around 50-70%. This measurement, taken during peak afternoon hours, aligns with forecast model consensus from earlier in the day predicting mid-20s potential but capped by persistent cloud cover and cooler air masses from the north, consistent with mid-April climatological norms averaging 19-20°C highs. Trader consensus at 100% implied probability reflects this verified data, as evening cooling reduces chances of exceeding 21°C. Realistic challenges would require an anomalous late-day heat burst or post hoc data revision by the China Meteorological Administration, both highly improbable given standard observation protocols. Market resolution awaits final daily report.

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 18 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.Official observations from Shanghai's Xujiahui observatory—the authoritative station for citywide meteorological records—confirm a daytime high temperature of 21°C on April 18, 2026, under mostly sunny skies with light winds and moderate humidity around 50-70%.
