**Persistent cloud cover, widespread rain, and high-altitude moderation are the dominant factors capping daytime heating in Mexico City on August 24.** Official forecasts from multiple sources (including NHC/NOAA-aligned models and local stations) show highs clustered between roughly 18–21 °C amid the ongoing rainy season, with 80–90 % chances of thunderstorms and overcast skies suppressing insolation. Mexico City’s 2,240 m elevation already limits peak temperatures relative to sea-level sites; combined with moist northeasterly flow and afternoon convection, this keeps the market-implied distribution tightly bunched around 19–21 °C. Recent days have featured similar conditions, with observed maxima in the low-to-mid 20 °C range but trending cooler under heavy cloud. Traders therefore assign the highest probabilities to 20 °C (35 %) and 21 °C (30.5 %), with 19 °C a close third, reflecting genuine uncertainty in exact rainfall timing and cloud persistence rather than model disagreement on the overall cool pattern. Newer model runs or clearer skies could shift resolution criteria, but current guidance favors the lower end of the distribution.
