Trader consensus on Polymarket prices a tight cluster around 26–31°C for Guangzhou's May 10 highest temperature at Baiyun International Airport, reflecting divergent short-range forecasts from models like CustomWeather (29°C high under overcast skies) and WeatherBug (27°C mostly cloudy). Persistent cloud cover over the past week—yielding recent highs near 26–27°C on May 6–8—has suppressed solar insolation amid high humidity and light winds typical of the subtropical monsoon onset, differentiating lower outcomes from potential clearing that could push toward 30°C+. Key variables include cloud thickness and any convective showers; watch China Meteorological Administration updates and ECMWF/GFS runs through May 9 for shifts ahead of resolution. Historical May averages hover near 29°C, underscoring the razor-thin scientific uncertainty.
