Traders see the highest temperature in Chengdu on August 5 clustered tightly around 32–35 °C because short-range forecast models show the city under the influence of a strong western Pacific subtropical high that favors daytime heating in the Sichuan Basin. Typical early-August climatology places afternoon maxima near 31–33 °C, yet recent ensemble runs indicate modest warming from clearer skies and light winds, pushing the upper tail of the distribution toward 35 °C or above. At the same time, scattered monsoon showers or increased cloud cover could shave 1–2 °C off peak readings, keeping lower outcomes viable. The near-even probabilities across the 32–35 °C band therefore reflect model spread in boundary-layer moisture and the timing of any convective cooling rather than any single dominant signal.
