Persistent heatwave conditions driven by a strong subtropical high over southwestern China are anchoring trader sentiment around 40–41°C for Chongqing’s July 26 maximum, with recent red alerts and 40°C+ readings since July 10 reinforcing this range. Ensemble guidance from major models shows tight clustering near these values amid typical July climatology of 33–37°C highs, while urban heat-island effects and elevated humidity amplify daytime peaks. Slight spreads between 39°C and 42°C outcomes reflect uncertainties in exact cloud cover, wind shifts, or minor convective timing over the next 48 hours that could trim or boost insolation. Official China Meteorological Administration updates and short-range model runs remain the key near-term catalysts.
