This market will resolve to the temperature range that contains the highest temperature recorded at the Guangzhou Baiyun International Airport Station in degrees Celsius on 1 May '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 Guangzhou Baiyun International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/guangzhou/ZGGG. 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 China Meteorological Administration (CMA) guidance and global forecast models like GFS and ECMWF project a high temperature of 27–29°C at Guangzhou Baiyun International Airport on May 1, positioning 28°C as the market-implied frontrunner at 44.5% amid trader consensus on partial clearing after April 29's cooler 25°C peak under overcast skies. In this humid subtropical climate, persistent low clouds could limit solar insolation and cap heating at 27°C, while breaks in cover—combined with urban heat island effects and a +3.3°C April warmth anomaly—favor 28–29°C aligned with early-May climatological averages of 28.6°C. Inherent model spread underscores uncertainty, with new CMA updates and ensemble runs due within 24 hours to refine probabilities before resolution using whole-degree observations.
