  • Moderate Air Quality in Los Angeles Today as Pollution Levels Fluctuate

    Moderate Air Quality in Los Angeles Today as Pollution Levels Fluctuate
    2025/11/29
    Los Angeles is experiencing moderate air quality today, with an Air Quality Index (AQI) reading of 60 as of this morning. The measurement reflects typical conditions for late November in the region, where air pollution levels tend to fluctuate throughout the day.[1]

    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.

  • Los Angeles Air Quality Moderate, Caution Advised for Sensitive Groups

    Los Angeles Air Quality Moderate, Caution Advised for Sensitive Groups
    2025/11/24
    Today in Los Angeles, the air quality is rated at a Moderate level, with an Air Quality Index, or AQI, around 60. This means air quality is generally acceptable, though there may be some risk for people who are unusually sensitive to air pollution, such as those with asthma, other respiratory illnesses, or heart conditions. For most people, outdoor activities can proceed as normal, but sensitive individuals may consider limiting prolonged outdoor exertion, particularly during midday when pollution is highest[6][3].

    The Moderate AQI is driven primarily by fine particulate matter, known as PM2.5. PM2.5 comes from a mix of sources, including vehicle emissions, industrial activity, and combustion from fires. These tiny particles can penetrate deep into the lungs and even enter the bloodstream, which is why they can be a concern for sensitive groups[2][6].

    Throughout 2025, Los Angeles has experienced improved air quality compared to previous years, with nearly 67 percent of days falling within the World Health Organization’s guidelines for safe air[1]. However, about one third of days in 2025 have registered beyond this level, so ongoing awareness and occasional alerts remain important.

    Typical AQI fluctuations in Los Angeles show slightly higher pollution levels in the late morning and midday, while early morning air tends to be cleaner. Today follows that trend, with the highest AQI readings expected between noon and early evening[1].

    For context, Southern California’s overall air quality can be affected by windblown dust, fires, and stagnant weather, especially in the cooler seasons. When such events occur, unusual spikes in pollution can be observed and air quality advisories are issued[4][2].

    In summary, Los Angeles residents can enjoy most outdoor activities with little risk today, but those with heightened sensitivities should remain cautious and limit heavy exertion outside, especially in the afternoon. Air quality continues to show gradual improvement citywide, but vigilance is advised when smoke, dust, or pollution events are present[1][2][3][6].

  • Moderate Air Quality in LA, Improvement Seen but Challenges Remain

    Moderate Air Quality in LA, Improvement Seen but Challenges Remain
    2025/11/24
    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].

  • Air Quality in LA Moderate, Experts Advise Caution for Sensitive Groups

    Air Quality in LA Moderate, Experts Advise Caution for Sensitive Groups
    2025/11/12
    Air quality in Los Angeles today, Wednesday, November 12, 2025, ranges from good to moderate across most regions. According to data from the South Coast Air Quality Management District, central Los Angeles County is experiencing a moderate Air Quality Index, or AQI, of 79, primarily due to fine particulate matter known as PM2.5. Northwest and Southwest coastal areas both have a moderate AQI of 69 and 66 respectively, also driven by PM2.5 levels. The Santa Clarita Valley and Antelope Valley report slightly lower AQI values of 56 and 58, still within the moderate category. Nearby mountain regions such as the San Bernardino Mountains are reporting good air quality, with AQIs in the low 40s.

    A "moderate" AQI, defined as a value between 51 and 100, means that air quality is generally acceptable, but there may be a minor concern for a very small number of individuals who are particularly sensitive to air pollution, such as those with pre-existing respiratory conditions. For the rest of the population, air quality poses little or no risk.

    The main pollutant contributing to the AQI today in Los Angeles is PM2.5, or fine particulate matter. These microscopic particles originate from vehicles, industrial emissions, and natural sources like wildfires. PM2.5 can penetrate deep into the lungs and potentially impact heart and lung health, particularly for vulnerable groups.

    Ozone levels remain low throughout the region today, meaning smog is not a significant concern. No widespread air quality alerts are in place. The forecast indicates similar air conditions throughout the day, so outdoor activities remain safe for most people. However, sensitive individuals should continue to monitor changes and reduce strenuous outdoor activity if experiencing symptoms.

    Recent atmospheric conditions, including a notable geomagnetic storm that made headlines with rare northern lights displays, have not negatively affected ground-level air quality in the Los Angeles Basin. Residents can enjoy typical fall activities, with only minimal air quality restrictions in effect for a small fraction of the population. Today’s air remains typical for the season, with regional variations consistent with historical patterns for this time of year[1][3][4].

  • Moderate Air Quality in Los Angeles on November 1st, 2025

    Moderate Air Quality in Los Angeles on November 1st, 2025
    2025/11/01
    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].
