Chongqing's subtropical climate and basin topography typically produce August daily highs averaging 32–34°C, with high humidity often moderating peak temperatures through increased cloud cover and convective rainfall. Current forecasts for August 20, 2026, show model outputs clustering near 32–33°C due to expected isolated thunderstorms and overcast conditions that limit solar heating, consistent with the market's strongest implied probabilities at those levels and the secondary weight on 31°C. A modest seasonal decline from mid-summer peaks further supports this range, while any clearer skies or delayed precipitation could briefly push readings toward 34–35°C. Traders appear to be weighting the balance of these near-term atmospheric variables and historical analogs heavily in the two days remaining before resolution.
