When does the first cold front arrive in Mexico? These are the 8 states that will be affected 


The winter season that is coming with the phenomenon of ‘El Niño’ could cause an increase in precipitation in the northwestern and northeastern areas of Mexico, in contrast to a decrease in the southern part of the country, predicted the National Water Commission (Conagua). ) for the 2023-2024 season, which coincides with the report of the National Office of Oceanic and Atmospheric Administration (NOAA). 

In a matter of days, in September, the cold front season will begin, which will last until May 2024. In that period, it is expected that 58 cold fronts will affect national territory that will be accompanied by rain, storms and even snowfall in some regions. 

Eight states of the country will be -the freezers- the most affected: 

– Aguascalientes 

– Coahuila 

– Chihuahua 



– Nuevo Leon 

 – San Luis Potosi 

– Zacatecas 

November could become the coldest month of the year, the meteorological authorities reported, especially with heavy rains, winds and temperatures below zero for the northern states of the country; they will be conditions of extreme cold that could put the population at risk, especially people living on the streets; in the rest of the states there will be decreases, but they will not be as extreme. 

Although the ‘El Niño’ phenomenon is associated with the summer season and high temperatures, when it occurs in winter, it favors the entry of more cold fronts into the country. 

It is the front part of a polar air mass that causes a drop in temperature in the area or region through which it passes. 

When a cold air mass collides with a warm air mass, the colder air, which is denser, wedges itself under the warmer part, generating movement and instability. 

– Temperature drops 

– Frost 

– Strong winds 

– High waves 

– Snowfall 

– Abundant cloudiness 

– Heavy rains 

Authorities suggest that citizens take preventive measures such as wearing thick clothing, wearing closed shoes, covering the body with a jacket, coat, scarf, gloves, in addition to consuming yellow fruits and vitamins rich in vitamin A and C. 

Most of the cold fronts that affect Mexico originate near the North Pole, then cross the United States, cross the national territory, from the northwest to the southeast and, depending on the time of year and its geographical location, can last from three to seven days.  

All those fronts that cross the national territory through the Isthmus of Tehuantepec receive the name of Tehuantepecos, which generate strong winds that cause thermal anomalies in the Gulf of Tehuantepec; When the polar masses cross the Gulf of Mexico, they are known as nortes. 

After the passage of the cold front, it is most likely that there will be rain, the humidity and temperature decrease and the wind blows more strongly from the north to the south, then the sky begins to clear but that is when a new mass of cold and dry air, which causes a further drop in temperature. 

– Avoid sudden changes in temperature. 

– When leaving a hot place, cover your nose and mouth to avoid breathing cold air.
