Recent forecasts for Chengdu point to persistent cloud cover and light rain on October 9 from the ongoing Huaxi autumn rain pattern, which typically suppresses daytime maxima in early October by limiting solar heating and enhancing evaporative cooling. Official guidance from sources such as the China Meteorological Administration and international models shows consensus for highs near 22–24 °C, with 35–60 % precipitation chances and light northerly winds that limit mixing of warmer air aloft. This aligns with climatological norms for the date, where average highs hover around 22 °C amid frequent overcast conditions. Traders appear to weigh the narrow spread among leading outcomes against potential forecast shifts from updated model runs, as even modest changes in rain timing or cloud thickness could alter the observed maximum by 1–2 °C before official reporting closes the market window.
