The Commission for Environmental Cooperation of the Megalopolis (CAMe) has issued a warning that the upcoming heat season in the Valley of Mexico will trigger the 'Double Hoy No Circula' program, aimed at addressing severe air quality issues. This measure, which restricts driving based on license plate numbers, is expected to be activated for up to 15 consecutive days due to the anticipated severe heat waves. According to the National Meteorological Service (SMN), residents can expect between three to five distinct heat waves from March to May 2026, with temperatures reaching up to 4 degrees Celsius higher than usual.

Furthermore, environmental authorities highlighted that adverse weather conditions, including high-pressure systems and clear skies, will contribute to intensified solar radiation and weak winds. These atmospheric factors will create a physical barrier, preventing the dispersion of air pollutants in the valley, which is already prone to poor air quality. This situation raises significant public health concerns for residents, particularly those vulnerable to pollution and extreme heat.

As the outlook for the coming months appears increasingly grim, local citizens and government officials must prepare for the possible health implications, including respiratory issues aggravated by high ozone levels. The activation of the 'Double Hoy No Circula' may also have economic impacts, as it restricts mobility and could influence daily commerce activities in one of the largest urban areas of the world.
