The month is not over yet March and they were beginning to feel very hot days in the city of Mexico and the Metropolitan Zone; and this temperature rise has continued during the first days of March, in fact, according to Guillermo Ayala Álvarez, Director of Early Warning at the Secretariat for Comprehensive Risk Management and Civil Protection, the high temperatures will continue like this for the month of April.
For all those who don’t like heat We have bad news for you, since a alert Early because in April they will register temperature rises in Mexico City that will break the historical record registered since 1985.
Why the increase in temperature in CDMX?
According to information from Ayala Álvarez, in March we will expect temperatures between 25 and 28 degrees, which we are already perceiving, while April is estimated to be the month further warm of history, from 1985 to date, with temperatures of 25 to 30 degrees, in a sustained manner, during the first 20 days of the month.
This phenomenon has an explanation and it is that during 2022 there was almost no rainfall, that is, it did not rain enough, this was also one of the reasons why the Cutzamala System only reached 50% of its capacity. But, what does the CDMX water storage system have to do with the high temperatures?
A lot! since it is surrounded by wooded areas which filter the heat waves before they reach the city. However, this natural barrier can no longer fulfill this task, since there is a growth of concrete, more asphalt, more glass buildings that continually refract solar radiation, causing a heat island, explains Ayala Álvarez.
All these factors cause the temperature annual average is about 12 degrees higher in the metropolis than in nearby rural areas.
What changes can we make to prevent future temperature increases?
It should be noted that those places where there are few green areas are more likely to get very hot, so if the City of Mexico It continues to grow without protecting the green areas, there will continue to be increasingly hot days, resulting in a risk for its inhabitants, especially those with socioeconomic vulnerability, such as street workers, bricklayers, drivers. Therefore, it is advisable that those citizens who can plant more trees, install gardens on the roofs and paint their facades white to reflect the radiation of the sun without heating the air.
