Trader sentiment for Chengdu’s August 10 maximum temperature is shaped by the latest ensemble outputs from global and regional models, which favor peaks of 35–37 °C under a strengthening subtropical high that promotes subsidence and reduced cloud cover across the Sichuan Basin. Basin topography traps heat and moisture, limiting nocturnal cooling while allowing strong daytime insolation when convective inhibition holds. Minor model spread on the timing of any scattered showers or boundary-layer mixing creates the tight contest between the 36 °C and 37 °C brackets. Historical August climatology shows typical highs near 32–34 °C, so current conditions represent a modest positive anomaly. The next cycle of China Meteorological Administration guidance and afternoon surface observations will be the key near-term catalysts.
