Mexico Braces for a Contrasting Climate: Cold Fronts, Heat Waves, and Potential Snowfall
Mexico is facing a complex weather pattern as of March 16, 2026, with a strong cold front (number 41) sweeping across much of the country while several regions simultaneously experience intense heat. The Servicio Meteorológico Nacional (SMN) warns of significant temperature drops, heavy rainfall, strong winds, and even the possibility of snow in higher elevations.
The Advance of Cold Front 41
The arrival of Cold Front 41 over the Gulf of Mexico is expected to bring cooler temperatures to most of Mexico, excluding the northwest, west, and south. States particularly vulnerable to intense rainfall include Puebla, Veracruz, Oaxaca, Chiapas, and Tabasco. Chubascos and strong to very strong rains are forecast for the northeast, east, center, south, and southeast, encompassing the Mexico Valley and the Yucatán Peninsula.
A strong to intense “Norte” wind event is also anticipated, with gusts reaching 100-120 km/h in Tamaulipas, and Veracruz. The Isthmus and Gulf of Tehuantepec (Oaxaca and Chiapas) could see gusts of 80-100 km/h, while Tabasco, Campeche, and Yucatán may experience winds of 50-70 km/h. These conditions will generate elevated waves along the affected coastlines.
Higher elevations are bracing for potential snowfall or sleet on the peaks of Pico de Orizaba, Cofre de Perote, Popocatépetl, Iztaccíhuatl, Sierra Negra, Nevado de Toluca, and La Malinche.
Heat Wave Persists in Multiple Regions
While much of the country prepares for colder temperatures, a heat wave continues to grip Jalisco (south and southwest), Colima (east), Michoacán (center and southwest), Guerrero (center and east), and Oaxaca (south and east). This heat is now extending into the southwest of Chiapas.
Maximum temperatures are predicted to reach 40-45°C in Guerrero (northwest) and Oaxaca (center and east). A broader area, including Baja California, Sonora, Sinaloa, Nayarit, Jalisco, Colima, Michoacán, Chihuahua (southwest), Durango (west), Zacatecas (south), Morelos, Puebla (southwest), Veracruz (south), Chiapas, Tabasco, Campeche, Yucatán, and Quintana Roo, will experience temperatures between 35-40°C. Some areas, like Baja California Sur, Aguascalientes, and the southwest of the State of Mexico, could see temperatures between 30-35°C.
Temperature Extremes and Potential Impacts
The stark contrast in temperatures presents significant challenges. Minimum temperatures are expected to drop to -10 to -5°C with frost in the mountainous areas of Chihuahua. Other mountainous regions in Durango, Coahuila, Nuevo León, and the State of Mexico could see temperatures between -5 and 0°C, also with frost. Temperatures between 0 and 5°C are forecast for mountainous areas of Baja California, Sonora, Zacatecas, San Luis Potosí, Jalisco, Michoacán, Guanajuato, Hidalgo, Tlaxcala, Puebla, and Veracruz.
Did you understand? The combination of strong winds and cold temperatures can create dangerous wind chill factors, increasing the risk of hypothermia.
