Recent forecasts for Mexico City indicate a daily minimum near 14–15°C on October 1, driven by the seasonal transition from the rainy period, with persistent cloud cover and scattered showers moderating radiative cooling overnight at the city's 2,240-meter elevation. Model runs show limited spread in daytime maxima around 23–24°C, but nighttime temperatures remain sensitive to exact cloud fraction, humidity levels, and any late-arriving moisture, creating the tight contest between sub-10°C and 19°C-plus outcomes. Historical October minima average near 9°C, yet early-month conditions often run several degrees warmer until drier air masses establish; updated National Meteorological Service guidance and refined model outputs over the next 48 hours will clarify whether clearer skies allow greater cooling or persistent instability keeps readings elevated.
