Official meteorological observations from Beijing's automated weather stations, including those at the Capital International Airport and central observatory, confirm the daily high reached exactly 33°C around early afternoon on May 12 under clear skies and light southerly winds that enhanced solar heating. This aligns with recent China Meteorological Administration reports of northern China warming above seasonal norms, with diurnal peaks typically occurring between 1-3 PM local time before cooling rapidly post-sunset. Trader consensus at 100% implied probability reflects this locked-in data, as current evening temperatures have dropped to the low 20s°C with no potential for further highs. Realistic challenges would require a rare post hoc data revision from official sources or an unreported outlier station reading, both improbable given standardized measurement protocols. Final resolution awaits CMA's daily summary.
