Recent forecasts from Mexico's national weather service and global models indicate a minimum temperature near 12–14°C for Mexico City on August 31, aligning with late-August climatology at the city's 2,240 m elevation where nocturnal radiative cooling typically produces lows of 11–13°C. Persistent cloud cover and scattered showers associated with the North American monsoon are limiting clear-sky cooling while also preventing significant warming, keeping overnight values tightly clustered. Ensemble spreads show modest uncertainty from timing of precipitation and boundary-layer moisture, which explains the market's near-even distribution across 12–15°C outcomes and very low probabilities assigned to extremes below 10°C or above 16°C. Updated model runs and local observations will refine the final minimum before resolution.
