Official observations from China Meteorological Administration stations confirm Chengdu's highest temperature on May 12 reached exactly 30°C, peaking in the early afternoon amid partly cloudy skies and light winds that limited further warming. This aligns with recent forecast consensus from global models like GFS and ECMWF, which projected highs of 28-31°C following a warming trend seen in prior days (e.g., 31°C on May 10). Trader consensus at 100% on 30°C reflects verified real-time data from multiple urban stations, representing skin-in-the-game agreement on the measured maximum. Realistic challenges are minimal post-sunset, though a rare official revision from outlier station readings could shift it; final CMA daily summary expected within 24 hours.
