Recent model consensus points to a daytime high of 22–23°C in Mexico City on October 7, driven by persistent cloud cover, scattered thunderstorms, and moderate northwesterly winds that limit surface heating during the late rainy season. These conditions align with October climatology, where average highs reach about 24°C but drop several degrees under widespread overcast skies and precipitation. Trader emphasis on the 22°C and 23°C outcomes reflects minor model differences in convective timing and cloud thickness, which can shift the afternoon peak by 1–2°C. Updated runs from agencies like the Servicio Meteorológico Nacional and global ensembles will clarify resolution thresholds as the date approaches.
