概要
The city's air quality has shown marked improvement throughout January 2026. According to historical data, 93 percent of the past 30 days in Los Angeles fell within the World Health Organization's safe air quality limits, indicating a Very Low health risk level.[1] When compared to the same date in previous years, today's AQI ranks as the third highest on January 29th over a five-year period, demonstrating better conditions than January 2025 and 2024.[1]
Hourly variations are notable during typical days. The highest AQI readings occur during afternoon hours, averaging 37 between 12 PM and 5 PM, while the cleanest air occurs in early morning hours around 6 AM with an average AQI of 26.[1] This pattern reflects common pollution dynamics in Southern California, where afternoon heating and traffic congestion typically elevate pollutant concentrations.
The annual perspective provides additional context. Los Angeles's 2026 AQI average of 44 represents a 15.4 percent improvement compared to previous years, with 2020 recording an average of 77 and 2023 recording 58.[2] This positive trend suggests that air quality management efforts and reduced emissions may be contributing to healthier conditions.
Night time air quality also shows variation, with average highest readings of 40 AQI occurring around 2 AM and lowest readings of 27 AQI around 5 AM.[1] These fluctuations are typical as overnight inversions and reduced atmospheric mixing can trap pollutants, though values remain within acceptable ranges.
For residents and visitors, today's Good air quality classification means that members of sensitive groups, including children, elderly individuals, and those with respiratory conditions, can engage in outdoor activities without significant concern. The sustained improvement in Los Angeles's air quality represents progress in addressing the region's historical air pollution challenges, though continued monitoring and pollution control measures remain important for maintaining these gains.
