Official surface observations from the Beijing Capital International Airport station, as tracked by the China Meteorological Administration (CMA) and Wunderground, confirm the highest temperature on May 9, 2026, reached no higher than 22°C, driving trader consensus to a near-certain 100% implied probability for this outcome amid thin liquidity. A potent cold air mass sweeping northern China over the past 48 hours brought overcast skies, gusty northwest winds, and reduced solar insolation, capping morning readings around 18°C and preventing afternoon warming spikes well below the historical May 9 average of 26°C. This positioning reflects finalized daily maximum data, with realistic challenges limited to post-resolution revisions by monitoring agencies—highly improbable given standardized measurement protocols—before the market closes at midnight UTC. CMA updates signal a sharp heatwave reversal starting May 10 with highs near 32°C.
