Trader consensus on Polymarket reflects close clustering around 17–20°C (implied probabilities of 23–24%), driven by China Meteorological Administration (CMA) and global forecast models (ECMWF, GFS) projecting mild early-spring highs near 19°C under partly cloudy skies and light southerly flow. Differentiating factors include variability in cloud cover evolution, which could reduce peak insolation by 1–2°C if thicker, versus urban heat island effects potentially boosting observed temperatures at Shanghai's downtown stations by 1°C above rural models. Historical April data shows average highs of 18°C with 2–3°C daily swings from frontal passages; no major developments in the past week, but daily CMA updates through April 1 may sharpen resolution amid typical spring uncertainty.

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.
