The Servicio Meteorológico Nacional (SMN) confirmed that a new cold front will bring the coldest day of the year to Mexico this week.

This weather event is significant because the sharp drop in thermal temperatures threatens public health and infrastructure across several regions. The interaction of the front is expected to produce extreme cold and rain, complicating travel and daily activities.

Rosario Quijano, a spokesperson for the SMN, said minimum temperatures are forecast to reach 0°C [1]. This freeze is accompanied by a wave of extreme cold that will affect various cities during Thursday and Friday.

In addition to the plummeting temperatures, the weather system will bring intense wind gusts. According to the SMN, wind speeds could reach up to 80 km/h [2] in some parts of the country. These high winds, combined with expected rainfall, increase the risk of localized disruptions.

The agency said the sudden temperature drop is the result of a new cold front moving through the region. Residents in affected areas are advised to prepare for the abrupt change in weather conditions as the front triggers a significant thermal decline across much of the country [3].

While the SMN has identified the specific risks associated with the wind and temperature, the agency continues to monitor the movement of the front to provide updated alerts for the most vulnerable cities.

“Minimum temperatures are forecast to reach 0°C.”

The arrival of the year's coldest day indicates a volatile atmospheric transition. When temperatures hit 0°C alongside high-velocity winds, the wind chill factor can make the perceived temperature significantly lower than the actual reading, increasing the risk of hypothermia and respiratory illnesses for the population.
