Today’s air quality in Los Angeles is classified as unhealthy, especially in the downtown and Compton areas, where EPA monitoring stations report elevated levels of fine particulate matter, known as PM2.5. These readings place air quality in the Unhealthy range, meaning that everyone may begin to experience health effects, and sensitive groups such as children, older adults, and those with respiratory or heart conditions should take extra precautions. Current conditions are influenced by recent wildfire smoke, which has raised the concentration of harmful particles across the city.

For Los Angeles, August is historically marked by higher ozone and particulate matter levels due to summer heat and stagnant air. The average Air Quality Index for August 2025 is tracking slightly better than previous years, but today’s spike is notable and marks a potential risk for outdoor activities. Over the last 24 hours, AQI levels in Los Angeles have fluctuated, reaching unhealthy levels in the afternoon during periods of higher traffic and heat. By the early morning hours, values are often lower and may return to moderate or even good ranges before climbing again as the day progresses.

Wildfire smoke remains a concern for the broader Southern California area, and wind shifts can rapidly change air quality conditions without much notice. Residents are advised to limit outdoor exertion, run air filtration indoors if possible, and check for real-time air quality updates before spending extended time outside. The Air Quality Alert in effect for neighboring Ventura County does not directly cover Los Angeles, but similar smoke patterns and weather conditions may impact the area intermittently.

Overall, today’s air quality levels should prompt caution for all Angelenos, especially those in neighborhoods experiencing the brunt of wildfire-related air pollution. It is recommended to follow local advisories and stay informed about changes throughout the day.
