Heat Wave and Air Quality Alert in Mexico City

Mexico City is preparing for a day of high temperatures during Holy Week, with forecasts indicating that the temperature will exceed 30 degrees Celsius between 2:00 PM and 6:00 PM. In light of this heatwave, Civil Protection has issued recommendations for the city's residents and visitors participating in religious events in the capital of the country.

The situation is exacerbated by the coincidence of the ozone season in the Valley of Mexico, which runs from February to June and can trigger environmental contingencies. The intense heat, weak winds, strong solar radiation, and low cloud cover contribute to the accumulation of pollutants in the air.

Authorities have identified stations with very poor air quality, such as Benito Juárez and Xochimilco, as well as others with poor air quality, including Villa de las Flores, Cuautitlán, Atizapán, Tultitlán, Los Laureles, Tlalnepantla, San Agustín, UAM Iztapalapa, Santiago Acahualtepec, Xalostoc, Fes Acatlán, Camarones, Gustavo A. Madero, Miguel Hidalgo, Cuajimalpa, Hospital General de México, Merced, Iztacalco, Pedregal, Centro de Ciencias de la Atmósfera, Nezahualcóyotl, Benito Juárez, Xochimilco, and Ajusco Medio.

If air quality worsens, local authorities will activate phase 1 of the environmental contingency, which involves the implementation of the Double Hoy No Circula in the Valley of Mexico. This Friday, the Hoy No Circula program remains regular for vehicles with license plates ending in 9 and 0 with blue stickers.

The Secretariat of Integral Risk Management and Civil Protection of Mexico City has announced that a yellow alert will be activated due to high temperatures on Good Friday, with forecasts reaching up to 32 degrees. Intense heat is expected in at least 10 municipalities of the city.

Air quality monitoring in the Valley of Mexico has indicated a concerning presence of pollutants, highlighting high concentrations of ozone, PM10, and PM2.5. Additionally, an alert has been issued for high ultraviolet radiation, reaching a level of 10. In this context, the question arises whether an environmental contingency will be activated on Good Friday.
