Forecast models for Chengdu on August 23 indicate a narrow range of daily highs centered on 32–33°C, consistent with late-summer climatology in the Sichuan Basin where the East Asian monsoon sustains high humidity and frequent afternoon convection. Basin topography and urban heat effects typically amplify daytime maxima, while variable cloud cover and scattered showers can suppress peaks by 1–2°C depending on timing. Historical August averages near 31°C, with occasional excursions above 35°C under clearer, subsiding conditions, frame the current tight clustering of trader probabilities. Updated numerical weather prediction runs from regional centers over the next 24–48 hours will likely refine steering patterns and precipitation chances that separate the leading outcomes.
