The fog and haze in Mexico City during October can last for several days, causing respiratory issues and reducing visibility.

The Concept of ‘Microclimate’ Zones within the City

Mexico City can be divided into several ‘microclimate’ zones, each with its own unique weather patterns and characteristics. The city’s geography, with its surrounding mountains and valleys, creates microclimates that can range from cool and misty to warm and dry. The fog and haze that form in October are most prevalent in the microclimates that are located at higher elevations, such as the neighborhoods of Coyoacán and San Ángel.

The microclimates within Mexico City have a significant impact on air quality, with some areas experiencing worse air quality than others. For example, the microclimate in the Valley of Mexico, which includes the city’s main urban center, tends to have worse air quality than the microclimates in the surrounding mountains.

Fog and Haze in Different Microclimate Zones

While the fog and haze that form in Mexico City during October can affect the entire city, some microclimate zones are more prone to these conditions than others. The microclimates in the higher elevations, such as Coyoacán and San Ángel, tend to experience more fog and haze than the microclimates in the lower elevations, such as the Valley of Mexico.

The table below compares the average temperature and precipitation in different microclimate zones within Mexico City during October:
