Recent forecast models from agencies including the China Meteorological Administration project a daytime high of 20–21°C for Chongqing on October 4, driven by persistent mid-level cloud cover, periods of moderate rain, and northerly winds that limit surface heating. These conditions align with climatological norms for early October, when average highs hover near 21–24°C amid seasonal cooling and frequent precipitation. Market-implied odds favor 21°C and 20°C as the leading outcomes because numerical weather prediction runs show consistent daytime maxima in this narrow range, with only modest model spread on exact timing of clearing. Final resolution will hinge on official station observations once the 24-hour period ends.
