Recent forecasts from the Servicio Meteorológico Nacional and international models indicate a minimum temperature near 13°C for Mexico City on October 10, driven by persistent cloud cover, high humidity near 90%, and scattered rainfall that moderates both daytime heating and nighttime radiative cooling at the city's 2,240-meter elevation. These conditions narrow the diurnal range, with overnight lows expected around 12–14°C amid light winds. Model consensus supports this moderate outcome over extremes, though small shifts in precipitation timing or cloud thickness could alter the exact minimum by 1–2°C. Updated SMN briefings and refined ensemble runs ahead of the date will refine trader assessments of the 12–14°C band versus cooler or warmer tails.
