Trader consensus on Polymarket assigns a 100% implied probability to a 29°C high temperature in Guangzhou today, driven by the latest China Meteorological Administration (CMA) forecasts and ECMWF/GFS ensemble model consensus projecting peaks of 28–29°C at Baiyun International Airport amid persistent cloud cover, 80% humidity, and scattered showers that limit surface heating and convective potential. Midday observations confirm 27–28°C readings, aligning with early May climatological averages of 29.3°C during subtropical monsoon onset, when overcast conditions typically cap daytime highs. Realistic challenges include unexpected afternoon clearing enabling brief solar insolation spikes or urban heat island amplification pushing briefly to 30°C, though robust model agreement and stable atmospheric patterns render this unlikely; track hourly airport METAR data for resolution.
