Observational data from Chengdu Shuangliu International Airport (ZUUU), the market's resolution source, confirm a peak temperature of 82°F (28°C) reached around 2-3 PM local time on May 11 under fair skies with light southerly winds and partial cloud cover, aligning perfectly with pre-day forecasts from services like AccuWeather projecting highs near 83°F. This trader consensus reflects the Sichuan Basin's typical early-May climatology, where average highs hover at 26°C amid frequent overcast conditions that cap solar heating, as seen in recent model runs emphasizing stable atmospheric stability. While final daily summaries from the China Meteorological Administration could incorporate minor revisions, only an unexpected late-day heat burst or data correction—unlikely given the observed cooling trend—might challenge this positioning.
