According to Fabián Vázquez Romaña, General Coordinator of the National Meteorological Service (SMN) of the National Water Commission (Conagua), the hottest months in 2025 for Mexico will be from February to June, due to the presence of heat waves that will affect the country.
During the press conference "Seminar on air quality in the dry-hot season in the ZMVM," Vázquez Romaña indicated that between February and April, accumulated rainfall will represent only a small percentage of the annual rainfall in Mexico, and mostly dry weather is expected in the central region of the country. Although a scenario as warm as in 2024 is not anticipated, the Coordinator warned that between 3 and 4 heat waves will affect the Megalopolis in 2025.
For his part, Dr. Jorge Zavala Hidalgo, from the Institute of Atmospheric Sciences and Climate Change (ICAyCC) of the National Autonomous University of Mexico (UNAM), mentioned that Mexico is currently under the La Niña phenomenon, expecting it to weaken and reach neutral conditions between April and May.
Regarding the Mexico City Metropolitan Area (ZMVM), Víctor Hugo Páramo Figueroa, Executive Coordinator of the Megalopolis Environmental Commission (CAMe), pointed out that, despite the decrease in historical levels of ozone and particles, days with high ozone concentrations are becoming more frequent in the dry-hot season from March to June. However, it is expected that it will not be an extreme year in terms of air quality, but conditions could favor pollution levels above average and cause various environmental contingencies during the hottest months from February to June 2025.
In conclusion, the heat season in Mexico is about to begin, and it is important to take precautions due to the multiple heat waves expected in 2025, with extreme temperatures forecasted, similar to the previous year.
