Recent forecasts from multiple meteorological sources project Mexico City’s October 6 high temperature in the 19–23 °C range, with model consensus centering near 20–22 °C amid persistent cloud cover, widespread rain, and light northerly winds. These conditions suppress daytime heating relative to the October climatological average of roughly 23–24 °C. Current observations on October 4 show similar overcast, rainy patterns that are expected to continue, limiting afternoon maxima. Trader-implied probabilities cluster on 21–23 °C outcomes because ensemble guidance shows little day-to-day variability and no strong warming signal before the market resolves. Updated model runs and any late shifts in steering flow or moisture could still adjust the exact peak within this narrow band.
