Persistent cloud cover, frequent afternoon thunderstorms, and the peak of Mexico City's rainy season suppressed daytime heating on August 24, 2026, producing an official maximum of 20 °C—well below the climatological August average near 23–24 °C. National weather service observations and station data confirm this value, driving the market-implied odds to near-certainty on the 20 °C outcome as resolution nears. Trader consensus reflects the strong alignment between real-time forecasts and post-event measurements. Minor revisions in the final official record or discrepancies between reporting stations remain the only realistic paths that could shift the outcome.
