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 4 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.Latest ensemble forecasts from global models like ECMWF and GFS project Shanghai's highest temperature on April 4 around 20–21°C, aligning with trader-implied odds favoring 20°C (23%) and nearby outcomes while boosting 24°C or higher to 35% amid potential subtropical high ridging for added warming. Cooler bins like 14°C or below (25.5%) reflect lingering uncertainty from a forecasted cold frontal passage and windy rain on April 3, which could suppress highs via increased cloud cover and northerly winds. Early April climatology averages 17°C highs, but spring variability—driven by jet stream positioning and East Asian monsoon onset—creates a 4–6°C model spread; daily China Meteorological Administration updates and new model runs through April 2 will refine resolution criteria based on official station measurements at Pudong or Xujiahui observatories.
