Forecast models from major agencies indicate scattered afternoon convection typical of Mexico City's rainy season will likely cap the August 22 maximum near 23–24 °C, aligning with the market's leading outcomes. At 2,240 m elevation on the Mexican Plateau, daytime heating is moderated by rapid radiational cooling and orographic effects, while monsoon moisture fuels cloud build-up and showers that frequently peak after solar noon. Recent observations show surface temperatures tracking seasonal averages, with light winds and high humidity reducing the potential for extreme heat. Minor divergences among model runs on storm timing and coverage create the narrow spread between 23 °C and 25 °C, as earlier or more widespread precipitation would suppress the peak while clearer intervals could allow a brief rise toward 25 °C. Updated guidance ahead of the diurnal cycle will refine these probabilities.
