Forecast models and official Servicio Meteorológico Nacional guidance point to a minimum of 13–15 °C in Mexico City on October 8, driven by persistent cloud cover, moderate rainfall, and light northerly winds that limit radiative cooling overnight. High humidity near 90 % and dew points around 12–13 °C further moderate temperature drops, consistent with regional influences from a moist airmass. Hourly guidance shows readings stabilizing near 13–14 °C in the early morning hours before daytime recovery to the low 20s. Market-implied odds cluster tightly on these values because traders balance the official 13–15 °C range against minor model spread and the possibility of slightly cooler pockets if rain ends earlier than expected. Upcoming official observations and any late-model updates will refine the final recorded low.
