Today, November 1st, 2025, Los Angeles is experiencing **moderate air quality**. The Air Quality Index, which measures key pollutants, is currently within the moderate category, meaning the air is generally acceptable for most individuals, but those with respiratory or heart conditions may want to take precautions. Specifically, ozone levels are moderately elevated, with a recent AQI reading of 56 indicating that while air quality is not classified as “good,” it is still below the threshold for unhealthy conditions. At the same time, the concentration of fine particulate matter—PM2.5—remains within the good range, measuring at 44. This combined profile results in a moderate health risk, primarily for sensitive groups like children, seniors, and those with existing health conditions[6].

The weather in Los Angeles today features mild temperatures around 19 degrees Celsius and relative humidity levels in the mid-thirties percent range, both of which help reduce the intensity of air pollution episodes. Winds have been light, at approximately one meter per second, meaning pollutants can linger longer near the ground before dispersing[3].

Over the course of 2025, Los Angeles has seen noticeable improvement in overall air quality compared to previous years. The annual average AQI currently stands at 46, which reflects an 8.6 percent reduction since 2021 and the lowest levels observed in the past six years. To date, 64 percent of the days this year have met the World Health Organization’s safe air quality guidelines, though 36 percent have exceeded them, typically during wildfire events or weather inversions that trap particulate matter near the surface[1].

For most healthy individuals, outdoor activities remain safe today. However, people who are especially sensitive to air pollution are advised to reduce prolonged exertion outside, particularly during the midday hours when ozone concentrations are highest. Those with allergies or asthma may benefit from keeping windows closed and using air filtration indoors[4][6].
