Air Quality Alerts Issued Across Southern California Due to Wildfire Smoke and Ozone Pollution
US · Published May 22, 2026
Air quality alerts have been issued across Southern California as wildfire smoke and elevated ozone levels push air conditions into unhealthy ranges.
The National Weather Service (NWS) has warned that the combination of fine particle pollution (PM2.5) from wildfire smoke and ground-level ozone poses significant health risks, particularly for vulnerable populations.
Affected areas include the Greater Los Angeles region, the San Fernando and San Gabriel Valleys, Santa Clarita Valley, the San Gabriel and Santa Susana Mountains, the Highway 14 corridor, and the Inland Empire region.

Why It's Important?

The poor air quality poses serious health risks, especially for children, older adults, pregnant women, and individuals with pre-existing conditions such as asthma, heart disease, or lung issues. Fine particle pollution (PM2.5) from wildfire smoke can penetrate deep into the lungs and bloodstream, causing inflammation and potentially triggering heart and lung problems. Elevated ozone levels can irritate airways, reduce lung function, and exacerbate chronic respiratory conditions. Even healthy individuals may experience symptoms such as coughing, wheezing, and shortness of breath during these conditions. The NWS emphasizes that the situation can change rapidly based on fire activity and weather patterns.
