**Recent forecasts for Chongqing on September 25, 2026, show highs clustered around 28–31 °C amid persistent cloud cover and light rain, keeping trader focus on the 25–28 °C range where probabilities are tightest.** Multiple models and local agencies indicate overcast or rainy conditions with light northerly winds and high humidity (70–90 %), which limit solar heating and cap daytime maxima below typical clear-sky values. Official guidance highlights continued unsettled weather from a regional system, producing scattered showers that enhance evaporative cooling and reduce surface temperatures by several degrees compared with drier analogs. Chongqing’s subtropical monsoon climate normally sees September highs near 28–30 °C; the current pattern of persistent moisture and reduced insolation favors the lower end of that range. Forecast spread arises from differences in predicted cloud thickness and timing of any brief clearing, creating the observed market clustering around 27 °C (30 %), 25 °C or below (25.5 %), and 28 °C (25 %). Warmer outcomes above 30 °C carry lower implied odds because additional rain or thicker cloud decks would be required to suppress heating further or allow brief warming. Traders are effectively pricing in the latest model consensus that favors modest temperatures due to these meteorological factors, with resolution hinging on the final 24-hour observational maximum reported by local stations.
