Today’s air quality in Los Angeles varies by region, but most areas are experiencing levels categorized as either good or moderate. In Central Los Angeles County, the Air Quality Index is 58, which is considered moderate, primarily due to fine particulate matter, known as PM2.5. Northwest, Southwest, South Coastal, Southeast Los Angeles County, and East San Gabriel Valley are enjoying good air quality, with AQI values ranging from 39 to 50. The West and East San Fernando Valley, along with the West San Gabriel Valley, are experiencing moderate air quality, with AQI readings between 53 and 56, also mainly from PM2.5. Throughout these areas, particulate pollution levels are expected to remain stable during the day.

An AQI in the moderate range means air quality is acceptable; however, particularly sensitive individuals may experience minor health effects. For those in areas rated as good, there are no anticipated health concerns related to air pollution.

It is important to note the presence of wildfire activity affecting broader Southern California, which may cause transient spikes in PM2.5 levels, especially downwind of active fires. Individuals who are sensitive to air pollution, such as children, the elderly, and those with respiratory or heart conditions, should be vigilant and limit outdoor activities if they notice visible smoke or receive local advisories.

Employers and outdoor workers should monitor air quality conditions, especially in the event of wildfire smoke, and follow Cal/OSHA guidelines, which include adjustments to work schedules and the use of N-95 respirators during periods of unhealthy air.

Overall, most of Los Angeles is experiencing a day where outdoor activities can continue as normal, but those with heightened sensitivities or close to wildfire-impacted zones should take precautions as needed[1][3].
