Traders see the closely bunched probabilities around 32–34°C for Chengdu’s August 7 high as reflecting genuine forecast uncertainty in the subtropical Sichuan basin. Persistent high humidity, scattered monsoon showers, and variable cloud cover from the East Asian summer monsoon are expected to modulate daytime heating, with official guidance and model consensus centering on a peak near 33°C. Recent days have produced similar maxima in the low-to-mid 30s under comparable conditions, while the possibility of stronger afternoon convection or clearer skies could push readings to 35°C or hold them near 32°C. Historical August climatology supports this narrow range, with average highs near 31–32°C but frequent excursions above 34°C when subsidence strengthens.
