Today’s air quality in Los Angeles is classified as moderate, according to the official forecast from the South Coast Air Quality Management District. Across central, coastal, valley, and surrounding areas, the Air Quality Index readings range from the low 50s to low 90s, with most locations measuring between 53 and 67. This means particulate matter, especially fine particles known as PM2.5 and ozone, are the primary pollutants and are expected to remain at similar levels throughout the day.

A moderate AQI indicates that air pollution levels are acceptable for the general public, but there may be a minor concern for people who are unusually sensitive to air pollution. For most individuals, outdoor activities can continue as usual. However, sensitive groups such as children, seniors, and individuals with respiratory or heart conditions may consider limiting prolonged exertion outdoors.

Smoke and ash from ongoing wildfires in Southern California, including the Rosa, Gifford, and Gold fires, have contributed to a dusty haze across the region. These fires elevate PM2.5 concentrations, which are fine inhalable particles that can penetrate deep into the lungs and may carry toxic compounds. Health experts note that exposure can aggravate respiratory and cardiovascular conditions, producing symptoms like wheezing, cough, throat pain, or eye irritation, particularly in sensitive individuals.

Residents are advised to monitor any changes in local conditions and follow health recommendations. Keeping windows closed, running air conditioning on recirculation, and using air purifiers can help reduce indoor exposure to wildfire smoke. For those who must go outside, wearing an N95 mask provides some protection against fine particulate matter.

Despite the wildfire impacts, Los Angeles’s average air quality in 2025 is improved compared to recent years, with a downward trend in the region’s annual AQI. This reflects broader air quality gains, although wildfire seasons can still produce short-term spikes and localized warnings.

The smoke advisory remains in effect, and residents should remain alert to updates from local health and air quality agencies as the wildfire situation evolves.
