Recent weather model consensus points to persistent cloud cover and thunderstorm activity over Mexico City on October 5, which is expected to limit solar heating and cap the daily maximum near or below the historical October average of 22–24°C. Mexico City’s high elevation of roughly 2,240 meters and urban heat-island effects typically allow peaks in the low-to-mid 20s under clearer conditions, but the current forecast pattern favors suppressed afternoon temperatures. This scientific setup explains why the 24°C-or-higher outcome holds the largest implied probability while the 20–22°C range clusters closely behind, with lower bins remaining unlikely absent a rapid clearing trend in the next model updates.
