Current forecast models from sources including Mexico’s Servicio Meteorológico Nacional point to persistent cloud cover, high humidity, and scattered thunderstorms through the night of August 23–24, limiting radiative cooling and keeping the lowest temperature in Mexico City near 12–14 °C. This aligns with recent observed minima in the 12–15 °C range amid above-average rainfall and supports the market’s close clustering around the cooler and mid-range bins. Key differentiating factors include the exact timing and intensity of overnight precipitation, which can enhance cooling through evaporative effects or suppress it via insulation from thick cloud decks, plus light variable winds that reduce mixing. Model consensus remains moderate given typical late-summer variability in the Valley of Mexico, with the next official updates likely to refine the precise minimum.
