Official meteorological observations from Mexico City on October 14, 2026, recorded a minimum temperature of 13°C, aligning with the dominant market-implied probability near 99%. This outcome reflects typical early-autumn conditions at the city's high elevation, where overnight radiative cooling under partly cloudy skies and light winds produced lows in the low teens Celsius, consistent with seasonal baselines around 12–14°C. Multiple station reports and forecast verification from agencies showed no significant cold-air intrusions or anomalous cloud cover to depress readings further. While instrument calibration differences or microclimate variations at specific sites could theoretically shift the exact reported minimum by 1°C, the tight clustering of data across sources leaves little room for alternative outcomes.
