Los Angeles Air Quality Update: May 13, 2025
The current air quality index (AQI) in Los Angeles has improved slightly from recent days, with readings hovering in the moderate range. As of yesterday, the AQI level was measured at 51, which falls within the "Moderate" category[5]. This indicates that while air quality is generally acceptable, there may be some health concerns for individuals who are unusually sensitive to air pollution.
Despite this moderate rating, Los Angeles continues to struggle with its historical air quality challenges. Earlier this year, the American Lung Association released its annual "State of the Air" report which named Los Angeles as the nation's smoggiest city for the 25th time in 26 years[2]. While the city has made significant progress—reducing unhealthy ozone days by nearly 40% since 2000—it still maintains this unfortunate distinction[2].
Los Angeles also ranks as the seventh-most polluted city in the nation for particle pollution[2]. This persistent issue remains despite decades of environmental regulations and improvement efforts.
The region faced additional air quality challenges earlier this year when wildfires that began on January 7 caused severe air quality impacts across Los Angeles[3]. More recently, Los Angeles County proclaimed April 28 - May 4 as Air Quality Awareness Week, highlighting concerns about fire debris, ash, and chemicals that can affect air quality[1].
For residents and visitors today, the good news is that no special precautions are needed for outdoor activities as the current air pollution poses little risk to most people[5]. However, those with respiratory sensitivities should remain aware of changing conditions, as AQI levels have fluctuated throughout recent days, with readings ranging from 47 to 58 over the past 24-hour period[5].
As summer approaches, staying informed about daily air quality reports becomes increasingly important, especially as Los Angeles continues to work toward improving its long-standing air pollution challenges.
