Recent forecasts from multiple models indicate overnight lows in Mexico City on August 22 will likely range from 13–16°C, driven by persistent cloud cover and scattered showers associated with the ongoing rainy season. High humidity and limited radiative cooling under overcast skies prevent sharper drops typical of clear high-altitude nights at 2,300 meters elevation. Recent days have seen minimums near 13–15°C with similar moisture patterns, and model consensus shows only modest variability tied to the exact timing and intensity of nocturnal precipitation. This uncertainty among closely matched market outcomes at 13–16°C reflects traders weighing slight differences in forecast clearing versus continued cloudiness.
