Official observations from Chengdu Shuangliu International Airport, the market's resolution source under China Meteorological Administration guidelines, confirm the highest temperature reached 29°C on April 17, driving trader consensus to a near-certain implied probability. Hourly readings peaked in the early afternoon amid mostly sunny conditions and light southerly winds, aligning with pre-event forecasts from CMA models predicting highs near 30°C but falling short due to increased mid-level cloud cover and urban heat moderation. This exceeds the mid-April climatological average of 23–25°C, influenced by a persistent high-pressure ridge over the Sichuan Basin. With the day concluded, only a rare post-processing data revision from delayed station reports could challenge this positioning, though historical revision rates for such metrics remain below 1%. Final CMA daily summary expected within 24 hours.
