Current forecast models from sources including WeatherBug and WindBorne project overnight lows near 13–15°C for Mexico City on October 9, driven by persistent cloud cover, widespread rain, and northerly flow at the city's 2,240-meter elevation. These conditions typically moderate radiative cooling at night while limiting daytime highs to the mid-teens Celsius, consistent with October climatology of frequent showers. Trader consensus on outcomes clustered around 9–17°C reflects model spread in exact minimum timing and intensity, while the 49% implied probability for 18°C or higher incorporates upside potential if clearer breaks develop. Updated global model runs and CONAGUA observations over the next 48 hours will likely refine these ranges ahead of market resolution.
