 Today, air quality in Los Angeles is rated as moderate on the Air Quality Index, with the most recent readings around 60, primarily influenced by fine particulate matter, known as PM2.5. This level of air quality is generally acceptable for most of the population, though individuals unusually sensitive to air pollution, including those with respiratory or heart conditions, should consider limiting prolonged outdoor activity. For the majority of Angelenos, outdoor activity is considered safe, but the air quality is not ideal for those with pre-existing health risks.

Recent months have seen an overall improvement in Los Angeles air quality, with more days falling within the World Health Organization’s safe air quality limits compared to previous years. Around 67 percent of days in 2025 so far have met these safe standards. However, one in three days still exceed recommended levels, highlighting ongoing challenges with pollution in southern California. On days when the air index moves higher within the moderate range, temporary increases in risk may occur for sensitive groups.

The main contributors to air pollution in the region remain fine particles and ozone, which are monitored by the South Coast Air Quality Management District. The city has made significant efforts to reduce emissions, but weather patterns and motor vehicle traffic continue to play a role in daily fluctuations. On clearer days, pollution risks decrease, but even when the sky is bright, invisible pollutants like ozone may still reach levels of concern.

Residents are encouraged to check daily forecasts, especially when planning outdoor activities, and to help further reduce pollution by minimizing vehicle use when possible. While the air quality is currently moderate and poses limited risk for most, awareness and ongoing improvements remain important for both public health and the region’s long-term air quality goals[3][8][1].
