The primary pollutants affecting Los Angeles today include particulate matter, with PM2.5 levels at 14 micrograms per cubic meter and PM10 at 30 micrograms per cubic meter. Additional pollutants measured include carbon monoxide at 398 parts per billion, nitrogen dioxide at 23 parts per billion, and ozone also at 23 parts per billion.[1]
Current weather conditions are contributing to air quality patterns, with partly cloudy skies, a temperature of 16 degrees Celsius, humidity at 87 percent, and wind speeds of 7 kilometers per hour. These relatively calm wind conditions mean pollutants are not being dispersed as quickly as they might be on windier days.[1]
Throughout the past 24 hours, Los Angeles air quality has been variable. The best reading reached 29 (Good) at 12:46 AM on November 28, while the worst peaked at 68 (Moderate) at 3:04 PM that same day. This fluctuation demonstrates how air quality typically improves during overnight hours when traffic decreases and temperatures drop, then worsens during afternoon peak hours.[1]
From a broader perspective, Los Angeles air quality has shown improvement compared to previous years. The 2025 annual average AQI stands at 47, representing a 7.7 percent improvement compared to 2020 through 2023 averages. Throughout 2025, approximately 67 percent of days have fallen within the World Health Organization's safe air quality limits, though 33 percent have exceeded them, indicating a moderate health risk particularly for individuals with respiratory or heart conditions.[2]
For residents today, current conditions allow for outdoor activities without significant concern. The moderate air quality rating suggests that while the general public faces minimal risk, people with respiratory conditions like asthma should consider limiting prolonged outdoor exertion during peak pollution hours.
