**Forecast models for Chongqing on October 15, 2026, indicate a minimum temperature near 19–21°C amid persistent cloud cover, light rain or showers, and northeasterly flow.** High humidity (often 90%+) and reduced radiative cooling from overcast skies moderate overnight lows, while recent days of similar conditions have kept temperatures above seasonal norms. International and regional guidance, including hourly profiles showing early-morning readings around 19°C before gradual warming, support this range and explain elevated market-implied odds for 19°C alongside nearby buckets. Model consensus on precipitation timing introduces some spread, but current data favor milder minima over sharper drops. Traders weigh these atmospheric factors against potential revisions in upcoming CMA or global model updates before resolution.
