Recent short-range forecasts from models and agencies place Chengdu’s July 18 maximum near 33–35 °C under typical mid-summer subtropical conditions, with scattered thunderstorms and high humidity expected to limit peak heating. The Sichuan Basin’s topography often traps moist air and moderates daytime maxima when cloud cover or precipitation arrives, while clearer periods allow brief spikes toward 36 °C. Current ensemble guidance shows modest spread in timing and coverage of convective activity, which directly influences whether the official station reading settles at 33 °C, 34 °C, or 35 °C. Historical July data indicate these values fall within the normal interquartile range, with occasional excursions above 37 °C only under stronger subsidence. Traders are therefore weighting the most recent model updates and any revisions ahead of the 48-hour window.
