Trader consensus has locked in a near-certain 100% implied probability for a 32°C high in Guangzhou on May 12, driven by confirmed observational data from the Guangzhou Baiyun International Airport station— the market's official resolution source under China Meteorological Administration protocols—recording a peak of 32°C during early afternoon amid persistent cloud cover and 70-80% humidity that sharply limited solar insolation and convective heating. This aligns with updated ECMWF and local forecast models projecting a cap at 32-33°C following a week-long cool spell with prior highs of 27-31°C, below May climatological averages of 29-30°C. Diurnal cooling has set in with evening readings dropping to 30°C under overcast skies, making further spikes unlikely; realistic challenges include brief clearing allowing a 1°C surge before sunset, though current atmospheric stability and declining solar angle render this improbable, with final CMA data expected post-midnight.
