Calidad del aire mejora en CDMX y Edomex, se evita doble Hoy No Circula

La calidad del aire en la Ciudad de México y el Estado de México mejoró, lo que evitó la activación de una nueva contingencia ambiental por ozono debido a la onda de calor. A las 15:00 horas, solo la estación en Tlalpan reportó mala calidad, mientras que en Cuajimalpa fue buena y el resto aceptable. La Comisión Ambiental de la Megalópolis (CAMe) levantó la contingencia del fin de semana y mantiene alertas por condiciones de estabilidad atmosférica.

La contingencia ambiental fase 1, suspendida el domingo, no se reactivó el lunes pese a altos índices de contaminación por una onda de calor y sistema anticiclónico que favorecen la acumulación de ozono.

El programa Hoy No Circula aplicó con normalidad el martes 28 de abril de 5:00 a 22:00 horas para vehículos con engomado rosa y terminación de placa 7 u 8. Quedan exentos motocicletas, vehículos eléctricos, híbridos categoría I y II, hologramas 00 y 0, entre otros.

Esta es la sexta contingencia en 2026 en el Valle de México, las anteriores por PM2.5 y ozono. La CAMe prevé para la semana del 27 de abril al 1 de mayo estabilidad atmosférica, vientos débiles y temperaturas sobre 30°C.

La CAMe recomendó reducir emisiones: limitar uso de autos, recargar gasolina fuera de horas pico, evitar aerosoles y solventes, acortar duchas y reparar fugas de gas.

The Comisión Ambiental de la Megalópolis (CAMe) has decided to maintain Phase I ozone air contingency in the Mexico City Metropolitan Area on Saturday, February 14, 2026, marking the third day of vehicle restrictions due to poor air quality. The peak ozone level recorded was 156 ppb at the Atizapán station in the State of Mexico. Authorities attribute the situation to a high-pressure system that promotes pollutant accumulation.

The Commission for the Megalopolis Environment (CAMe) reported that Phase 1 air quality contingency remains in effect this Friday, February 13, in the Metropolitan Zone of the Valley of Mexico due to poor air quality.
