La Delegación Presidencial de la Región Metropolitana declared an Environmental Alert for the Santiago basin for Saturday, July 25, 2026, following a recommendation from the Seremi del Medio Ambiente RM. Despite monitoring stations recording air quality in the “Good” range on Friday, unfavorable meteorological forecasts indicate that basin ventilation will worsen in the coming hours.
Enforcement Measures and Restrictions Across the Metropolitan Region
Authorities have urged residents of the Región Metropolitana to comply with the mandated restrictions. The primary prohibition targets residential heating units that burn solid fuels, such as wood and other wood derivatives, across the entire region. According to the Delegación, wood-pellet heaters are the sole exception to this rule.
The Seremi de Salud de la RM, working alongside local municipalities and Carabineros, will handle enforcement and apply corresponding sanctions for noncompliance. Additionally, agricultural burns remain prohibited under a seasonal restriction that runs from March 1 through October 31, with monitoring managed by teams from SAG and Conaf throughout the Región Metropolitana.
Weekend Exceptions and Sports Recommendations
Vehicle restriction measures will not apply this Saturday due to the weekend schedule, serving as the sole exemption within the announced package. For athletic and physical routines, official guidance advises individuals to avoid high-exertion efforts and focus on activities requiring lower oxygen consumption. Authorities also suggest performing these exercises indoors whenever possible.
