The National Disaster Prevention Center (Cenapred) explains that the warming of the air and clear skies contribute to the increase in temperature and the lack of rainfall, which aggravates the drought in various regions of Mexico. Among the states most affected by the dry spell are Campeche, Colima, Chiapas, Guerrero, Hidalgo, Michoacán, Morelos, Nuevo León, Oaxaca, Puebla, Quintana Roo, San Luis Potosí, Tabasco, Tamaulipas, Tlaxcala, Veracruz, and Yucatán.
The dry spell begins a few weeks after the summer solstice, which occurs on June 21, and is characterized by temperatures exceeding 37 degrees Celsius, as well as dry weather and clear skies. To prevent negative health effects during this period, it is advisable to stay hydrated, use sunscreen, avoid sun exposure between 10 AM and 4 PM, and use umbrellas, caps, or hats.
The National Meteorological Service (SMN) forecasts the arrival of several heat waves in Mexico during the year 2025. Additionally, it is expected that from March to June, Mexico City will experience weather with clear skies, which could lead to very hot environments and high levels of UV radiation, causing heat exhaustion and excessive sweating.
For their part, specialists indicate that high temperatures will begin to be felt in Mexico from February to April, coinciding with the weakening of the 'La Niña' phenomenon and the transition to neutral conditions between April and May. It is estimated that this year in the central region, where Mexico City is located, there will be between three and four heat waves, although the probability of an extreme scenario like that of 2024 is ruled out.
The dry spell, a phenomenon of about 40 days of significant temperature increase due to excessive air warming, is a challenge for various states in Mexico where the effects of drought intensify. The population must be prepared and follow recommendations to mitigate the negative health impacts caused by this climatic phenomenon.
