Today’s air quality in Los Angeles varies by region, with much of the county experiencing moderate conditions. Central Los Angeles County has an Air Quality Index of 56, categorized as moderate, mainly due to PM2.5 particles. Northwest and Southeast Los Angeles County also report moderate air quality, with AQI values of 55 and 53 respectively, both driven by PM2.5 levels. Residents in these areas can generally go about their daily activities but may consider limiting prolonged outdoor exertion, especially those with pre-existing respiratory conditions[1].

Some areas are enjoying better conditions. Southwest and South Coastal Los Angeles County both have good air quality today, with AQI levels at 50 and 44, respectively. This indicates that the air is generally clean, and there is minimal risk from exposure to air pollution[1].

There are zones with elevated health concerns, particularly the East San Gabriel Valley, where the AQI has reached 115. This is classified as unhealthy for sensitive groups due to elevated ozone concentrations. Children, elderly adults, and anyone with respiratory or heart problems should limit outdoor activities in this area, especially during the afternoon. The cleanest air in this region is forecast between 6 PM and 10 PM, making that the best window for time spent outdoors[1].

Air quality in the West and East San Fernando Valley and the West San Gabriel Valley also falls in the moderate range today, with AQI values from 64 to 71, attributed primarily to ozone. Residents in these valleys may notice some haze and should be aware of possible respiratory irritation, especially in the afternoon hours when ozone peaks[1].

Overall, Los Angeles is not experiencing severe pollution today, but sensitive individuals in specific neighborhoods—particularly the eastern valleys—should take precautions against moderate to high ozone levels. For most residents, outdoor activities can continue as normal, but it is always wise to check the AQI for your neighborhood before spending extended time outdoors[1].
