Official Servicio Meteorológico Nacional (SMN) observations from key Mexico City stations, including Observatorio Central Tacubaya and Benito Juárez International Airport, recorded a high of exactly 25°C on April 2, cementing 100% market-implied probability for that outcome as traders aligned with verified hourly data amid partly cloudy skies and light winds. This peak fits April climatology for the city's 2,240-meter elevation, where dry-season highs typically range 24–27°C, consistent with pre-event SMN forecasts of 25–27°C and ensemble model guidance showing limited convective activity. Though observational records provide strong scientific certainty, realistic challenges could arise from rare data revisions if discrepancies emerge between primary and auxiliary sensors, prompting SMN review before final resolution.
