Recent forecasts for Mexico City on October 1 point to daytime highs near 23°C with overnight lows likely in the 13–15°C range, though model runs show sensitivity to cloud cover and scattered showers that could moderate radiative cooling at the city's 2,240-meter elevation. This high-altitude setting typically produces large diurnal swings, with clearer skies allowing stronger nighttime temperature drops below historical early-October averages around 12–14°C. Trader consensus remains split near 50% on extremes because short-range guidance from agencies like Mexico’s Servicio Meteorológico Nacional still carries uncertainty over precipitation timing and humidity levels, which directly influence whether the daily minimum settles in the mid-teens or deviates toward cooler or warmer outliers. Updated model outputs expected in the next 24–48 hours will likely tighten the range ahead of resolution.
