Official observations from Mexico City's Servicio Meteorológico Nacional (SMN) stations and Benito Juárez International Airport confirm the highest temperature reached exactly 23°C on April 1, 2026, driving trader consensus to a near-certain 100% implied probability for this outcome. Cloud cover and scattered showers from a passing weather system suppressed daytime heating despite the city's high elevation (2,240 meters) and typical April highs around 26°C, aligning with pre-event forecasts from SMN predicting a maximum of 23°C amid intervalos de chubascos. This skin-in-the-game positioning reflects verified hourly METAR data peaking at that level, though rare scenarios like post hoc quality-controlled revisions uncovering a higher reading from a secondary station could theoretically challenge resolution. No further updates expected as data finalizes.
