These are the states in Mexico that will be affected by ‘La Niña’ phenomenon in the hottest days of 2024


The recent increase in temperatures in the country warns that the records reached in 2023 could even be broken.

Also known as ‘intra-summer drought’ or ‘veranillo’, the Canicula will significantly affect the national territory in 2024, according to the predictions of the National Meteorological Service (SMN), thanks to the arrival of the natural phenomenon known as “La Niña” and, although the entire country will be experiencing difficult days, these will be the most affected states.

Currently, Mexico is going through the third of five heat waves that raised the thermometer to 33 degrees Celsius in the Mexican capital and more than 45 degrees in other parts of the interior of the Republic, a situation that worries residents since the Heat Wave normally It is the time of year when the heat is most intense.

In that sense, it is important that you keep an eye on the official networks of the SMN and the Federal Government in case special measures are taken to combat the effects of high temperatures which, according to forecasts, will not drop significantly.

When does the Canicula begin?

Summer is the second hottest season of the four seasons, and it is precisely at the solstice that ends spring in the northern part of the planet when the Canicula is officially determined; that is, between June 20 and 21 when the midday sun is at its highest point of the entire year.

However, data from the National Meteorological Service highlights that it extends until mid-July or even early August, just as happened in 2023 when it officially began on July 21. Although it is impossible to predict the exact day on which it will hapen, a situation similar to the date on which it will end since everything depends on the meteorological phenomena that accompany it.

Although the Canicula are not considered a natural phenomenon as such and are normally perceived during the summer, a simpler explanation is that these are the days in which very high temperatures are recorded and there is no chance of rain.

What is ‘The Niña?

It is a climatic event characterized by the anomalous cooling of the surface waters of the central and eastern equatorial Pacific Ocean. This phenomenon is part of the climate cycle known as the El Niño-Southern Oscillation (ENSO), and occurs at irregular intervals, generally every 2 to 7 years.

La Niña has various repercussions globally, including:

Increased rainfall in some regions, such as Southeast Asia and northern Australia.

More intense droughts in other areas, such as the western coast of South America.

Impacts on global temperatures, generally leading to colder conditions in the Northern Hemisphere during winter.

Alterations in hurricane patterns, with an increase in activity in the Atlantic and a possible decrease in the Pacific.

This phenomenon can have significant effects on agriculture, fishing and water availability, as well as the incidence of natural disasters such as floods and droughts.

Which states will be most affected?

Information issued by the SMN, the entities that will have the highest temperatures during the summer of 2024 are Colima, Guerrero, Campeche, Chiapas, Hidalgo, Morelos, Michoacán, Nuevo León, Puebla, Oaxaca, Quintana Roo. Tabasco, San Luis Potosí, Tamaulipas, Veracruz, Tlaxcala and Yucatán, the vast majority located in the east, center and northeast of the Republic.
