Recent forecasts for Mexico City on October 8, 2026, show overnight lows clustered around 12–14°C under persistent overcast skies, light variable winds, and widespread rain or thunderstorms, with high humidity near 90% limiting radiative cooling at the city’s 2,240-meter elevation. Model runs differ modestly on exact timing of any partial clearing or wind shifts that could allow a brief dip toward 12–13°C versus stabilization near 14–15°C, keeping those outcomes nearly tied in market-implied odds. Historical October minima average near 9–11°C under clearer conditions, but today’s moist, cloudy regime supports the tighter 13–14°C consensus reflected in trader positioning ahead of final observational data.
