Recent forecasts for Chongqing on October 3 indicate a high near 20–23°C under cloudy skies with moderate to heavy rain expected, which limits daytime heating through reduced solar radiation and evaporative cooling. Model runs show close agreement on maximum temperatures in the low 20s Celsius, consistent with early October climatology where averages hover around 21°C amid frequent precipitation. The tight market split between 20°C and 21°C reflects uncertainty in exact peak timing and rainfall intensity, with traders weighting official China Meteorological Administration guidance and ensemble outputs heavily. Updated model runs and local observations over the next 48 hours will likely refine the resolution threshold.
