**Persistent cloud cover, light to moderate rain, and stable atmospheric conditions have driven trader consensus toward a 24°C daily maximum in Chongqing on September 30, 2026.** Official forecasts from regional meteorological services consistently project highs in the 23–25°C range under overcast skies with high humidity (around 85–90%) and light winds, limiting solar heating and convective warming. Model consensus aligns with historical late-September baselines for the region, where seasonal cooling and frequent precipitation keep peaks near this threshold. The 100% market-implied probability reflects this strong alignment of current observations and short-range guidance. Unexpected rapid clearing or stronger subsidence could push readings above 24°C, though current data show low likelihood of such shifts before resolution.
