Recent forecasts for Mexico City on September 2 point to overnight lows near 13–15°C, shaped by the ongoing rainy season with high humidity, frequent afternoon thunderstorms, and persistent cloud cover that limits radiative cooling overnight. Model consensus from agencies shows partly cloudy to overcast conditions with light winds and dew points around 13–14°C, moderating the typical 12°C September average low at the city's high elevation. Trader sentiment clusters tightly around 11–15°C because small shifts in precipitation timing or cloud thickness could alter minimum readings by 1–2°C, while drier or clearer spells remain unlikely given seasonal moisture patterns. Updated model runs and local observations over the next 24 hours will refine these probabilities.
