Trader consensus shows nearly even implied probabilities for extremes versus moderate outcomes in Mexico City's October 3 minimum temperature, reflecting genuine forecast uncertainty in highland radiative cooling amid variable cloud cover and light precipitation. Current model runs from sources like the Met Office and Yr indicate overnight lows near 14–16°C under mostly overcast skies with northerly winds, consistent with early October climatology where typical minima range 11–14°C. Recent rain and high humidity have limited clear-sky cooling, while steering patterns and any model shifts in the next 48 hours could tip thresholds around 13–17°C. Updated National Meteorological Service guidance and ensemble runs will likely refine the outlook before resolution.
