Trader consensus assigns 100% implied probability to a 33°C high in Guangzhou on May 13, anchored by official hourly surface observations from the Guangzhou Baiyun International Airport weather station (ZGGG), which recorded a midday peak of 33°C under partly cloudy conditions with light southerly winds enhancing solar insolation. This exceeds China Meteorological Administration preseason forecasts of around 28–30°C, likely due to a transient high-pressure ridge suppressing clouds and boosting daytime heating beyond May climatological norms of 29–31°C. As evening progresses with temperatures now below 30°C and sunset nearing, realistic challenges would require an improbable late-afternoon convective lapse or measurement revision, with final daily data from CMA expected after 23:59 UTC+8.
