 Air quality in Los Angeles today is mostly in the moderate range, with the primary pollutant being fine particulate matter, known as PM2.5. In central Los Angeles County, the Air Quality Index, or AQI, is measured at 58, which is classified as moderate, meaning air quality is acceptable but there may be some risk for people who are unusually sensitive to air pollution. Northwest coastal and southwest Los Angeles County also report moderate AQI levels at 58 and 56, respectively. South and southeast Los Angeles County show similar AQI numbers, all in the mid-50s. This trend of moderate air quality holds across large urban and suburban sections of the county throughout the day.

The West and East San Fernando Valley and the West San Gabriel Valley also experience moderate air quality, with AQI levels between 53 and 77. The East San Gabriel Valley, however, reaches an AQI of 101 for ozone, which is considered unhealthy for sensitive groups. Individuals with respiratory conditions, young children, and older adults in that area are advised to limit prolonged or heavy outdoor exertion.

Historical air quality data from this month indicates an improvement compared to previous years, with the AQI trending lower, suggesting cleaner air than in the recent past. Over the last 24 hours, Los Angeles's AQI varied from a low of 43 during the early morning to a high of 60 in the evening, both readings remaining within the moderate range.

No major spikes in pollution or hazard alerts have been issued. Residents are encouraged to follow routine guidelines, such as staying indoors during peak pollution hours if sensitive, but for the average person, outdoor activity remains generally safe in most areas of Los Angeles today[1][2].
