Today’s air quality in Los Angeles falls within the moderate range for the Air Quality Index, registering an AQI of 55 according to recent monitoring. This means air quality is considered acceptable for most residents, though some people unusually sensitive to pollution—such as those with asthma or heart conditions—may experience minor health effects and should limit prolonged outdoor exertion during times when the AQI peaks[1][2].
Throughout the last 24 hours, Los Angeles experienced its highest AQI reading of 67 overnight at 3 AM and its lowest reading of 36 during the evening at 6 PM. These figures suggest the pollution levels fluctuate across the day, with nighttime and early morning hours typically recording higher pollution levels[1].
Looking at a broader perspective, Los Angeles air quality in 2025 has generally improved compared to previous years, with the average AQI this year at 46, a decrease of nearly 10 percent from recent years. In fact, 67 percent of days in 2025 so far have remained within World Health Organization’s safe air quality limits[1].
The main pollutants tracked today include ozone and particulate matter (PM2.5 and PM10). Both ozone and fine particulates can potentially cause respiratory issues if present at high levels. However, recent measurements for Los Angeles report ozone levels at 34 and PM2.5 at 23, both within the “Good” category under federal standards, meaning they are unlikely to pose health risks for the general population at these values[5][4].
For healthy individuals, outdoor activity is generally safe. However, people with pre-existing respiratory conditions are advised to be cautious and limit strenuous exertion outdoors during periods when air quality reaches the higher end of the moderate AQI range[2]. As of today, Los Angeles residents can expect air that is mostly safe for daily routines, with only moderate advisories for sensitive groups.
