  • Los Angeles Experiences Excellent Air Quality for Outdoor Activities

    Los Angeles Experiences Excellent Air Quality for Outdoor Activities
    2026/02/07
    Los Angeles is experiencing **good air quality** today, with conditions favorable for outdoor activities across the region.[5]

    The current Air Quality Index (AQI) reading stands at 33, classified as good according to EPA standards.[5] This measurement indicates that air pollution poses little or no risk to the general public, and no special health precautions are needed.[3] Primary pollutants measured include ozone, particulate matter (PM2.5), and PM10, all within acceptable ranges.[5][8]

    Recent weather patterns have supported improved air quality in the Los Angeles area. Rainfall recorded in the region has helped reduce airborne particulates, contributing to the current favorable conditions.[2] Wind speeds and atmospheric conditions continue to support good dispersion of pollutants.

    Los Angeles has shown remarkable air quality improvements throughout 2026. The annual AQI average of 34 represents a 31.1% improvement compared to previous years, with 2020 recording an average of 53 and 2021 at 55.[1] Over the past 35 days in 2026, 94% of days have fallen under the World Health Organization's safe air quality limits, demonstrating significant progress.[1]

    Hourly fluctuations typically occur throughout the day in Los Angeles. Data shows that air quality tends to be best during mid-morning hours, averaging around 29 AQI between 9 AM and 9 AM, while afternoon hours between 12 PM and 2 PM average 39 AQI.[1] Nighttime readings vary more substantially, with early morning hours around 2 AM averaging 47 AQI, likely due to temperature inversions that trap pollutants near ground level.[1]

    For residents planning outdoor activities, conditions are ideal. The air quality supports recreational activities, exercise, and general outdoor engagement without restrictions. Those with respiratory sensitivities should continue monitoring forecasts, though current conditions present minimal concern.[3]

    Looking at regional context, while Los Angeles County historically ranks among the top three U.S. counties for unhealthy air quality days, the 2026 data reflects substantial environmental improvements, positioning the region favorably compared to recent years.

  • LA Enjoys Excellent Air Quality with AQI of 36

    LA Enjoys Excellent Air Quality with AQI of 36
    2026/01/31
    Los Angeles is experiencing Good air quality today, with an Air Quality Index (AQI) of 36, reflecting a significant improvement compared to recent years.[1] This rating means air pollution poses little or no risk to the general public, and outdoor activities can be pursued safely.[3]

    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.

  • LA Air Quality Sees Highs and Lows in 2025, Wildfire Smoke and Industry Pollution Challenges Persist

    LA Air Quality Sees Highs and Lows in 2025, Wildfire Smoke and Industry Pollution Challenges Persist

    Los Angeles Air Quality: Current Status and Recent Trends

    The air quality in Los Angeles today is good, according to real-time monitoring data.[6] This represents a relatively positive snapshot for a region that has struggled with air pollution challenges in recent years.

    Los Angeles County currently ranks third among U.S. counties for unhealthy air quality days, trailing only Riverside and San Bernardino Counties in California.[1] However, the data tells a more nuanced story about seasonal patterns. Throughout 2025, the county experienced significant variation in air quality conditions. January began with 7 total unhealthy or hazardous air days, while February improved dramatically to just 1 such day. Spring months showed improvement overall, but summer months proved more challenging, with August registering 24 unhealthy or hazardous air days—the worst of the year.[1]

    Several factors contribute to Los Angeles's persistent air quality challenges. Wildfire smoke remains a significant threat, particularly during fire season. In January 2025, Cal/OSHA issued alerts regarding unhealthy air caused by active wildfires impacting the region.[3] Beyond natural disasters, the region faces unique pollution sources. Long Beach and communities near shipping yards have been documented with methyl bromide contamination, a fumigant technically banned decades ago that continues appearing in the air.[4]

    The region's geography plays a crucial role in air quality challenges. The San Gabriel Mountains north of Los Angeles trap pollutants and limit dispersion, contributing to concentrated pollution zones. Research has identified a pollution hotspot in Pasadena, where residential wood-burning concentrations reach particularly high levels.[2]

    The Air Quality Index measures multiple pollutants including ozone, nitrogen dioxide, and particulate matter (PM2.5 and PM10).[1] Throughout 2025, Los Angeles residents experienced 39 good air quality days, 233 moderate days, and 93 total unhealthy or hazardous days.[1] While today's good air quality is welcome, the broader pattern suggests that residents should remain vigilant, particularly during summer months and fire season when conditions typically deteriorate. Checking real-time air quality data remains essential for vulnerable populations, including children, elderly individuals, and those with respiratory conditions.
