**Current forecasts from sources like AccuWeather, WeatherBug, and others point to a Mexico City low near 12–14°C on October 11, driven by lingering moisture, cloud cover, and the city's high elevation of roughly 2,240 meters.** Nighttime temperatures hinge on radiational cooling rates under partly cloudy skies versus clearer conditions that enhance longwave heat loss. Recent showers and moderate easterly flow have kept overnight lows milder than the October climatological average of about 9–11°C, limiting cold-air advection while suppressing extreme diurnal swings. Model consensus shows limited spread in guidance, yet the near-even market odds on extremes (≤8°C or ≥18°C) reflect residual uncertainty in exact cloud timing and boundary-layer moisture, which can shift the minimum by several degrees. Upcoming model runs and official updates from regional meteorological services will clarify whether enhanced cooling or residual warmth prevails.
