Official meteorological observations from Mexico City stations recorded a daily maximum of exactly 20°C on August 24, 2026, under cool, rainy conditions with widespread cloud cover and temperatures well below seasonal averages. This aligns with Servicio Meteorológico Nacional data and nearby station reports showing highs around 68°F amid a cold front and precipitation, driving near-certain market-implied odds for the 20°C outcome. Trader consensus aggregates real-time verification once the observation window closed. Rare challenges could include post-event data revisions by monitoring agencies or disputes over which specific station defines resolution criteria.
