Recent forecasts from the China Meteorological Administration and international models converge on a daily high of 32–34°C for Chongqing on August 21 under subtropical monsoon conditions with light rain, overcast skies, and humidity above 70%. The Sichuan Basin’s orographic effects—surrounding mountains driving afternoon convection and cloud cover—typically suppress peak temperatures relative to historical August extremes near 35–37°C. These conditions position 33°C as the leading outcome at 41.5% market-implied probability, followed by 32°C and 34°C, reflecting trader consensus on stable model guidance rather than heatwave intensification. Minor shifts in steering patterns or reduced cloud cover could still push readings higher, though current data favor the narrow 32–34°C range ahead of final model updates.
