**Short-term numerical weather prediction models from sources like the China Meteorological Administration and international ensembles indicate a highest temperature in Chongqing on September 1 around 33–36°C under mostly clear skies and light variable winds, consistent with the ongoing post-summer pattern.** This places the outcome squarely in the intermediate range, where model spread arises from subtle differences in boundary-layer moisture and local orographic effects around the Sichuan Basin. Recent days have featured stable high pressure with highs climbing from ~31°C, supporting gradual warming absent any frontal passage or typhoon influence. Historical September baselines show early-month maxima frequently in the low-to-mid 30s°C, with extremes rarer this early in the transition season. Trader balance between the ≤29°C and ≥39°C tails reflects residual uncertainty in the final 48-hour model runs and potential microscale variability in official station readings rather than any fundamental shift in synoptic conditions.
