El Paso, Texas Air Quality Today
AirHistory tracks long-run EPA monitoring rather than live readings, so for the live number check AirNow.gov below. As a baseline, El Paso, Texas's most recent EPA year (2023) posted a median AQI of 64 (Moderate) against a 5-year median of 60 and an overall Grade of D. The dominant pollutant is Fine Particulate Matter (PM2.5), which tells you which days are most likely to spike.
Check Today's Live AQI in El Paso, Texas
AirHistory is built on 10 years of EPA Air Quality System records, so it shows you what air quality in El Paso, Texas typically looks like — not the live reading for this exact hour. For today's real-time AQI, check AirNow.gov (the EPA's official live index) or the AirNow Fire and Smoke Map during wildfire season.
That said, the history is the best predictor of a normal day. In 2023, El Paso, Texas posted a median AQI of 64 (Moderate), with 69 "Good" days and 19 days that crossed into "Unhealthy for Sensitive Groups" or worse. The dominant pollutant, Fine Particulate Matter (PM2.5), is the one most likely to push today's number up — Fine particulate matter — particles less than 2.5 micrometers across — comes mostly from combustion: vehicle exhaust, wildfire smoke, residential wood burning, and industrial emissions. Because these particles are small enough to enter the bloodstream, PM2.5 is the pollutant most strongly linked to cardiovascular disease, respiratory illness, and premature death.

What's in El Paso, Texas's Air?
The dominant pollutant in El Paso, Texas is Fine Particulate Matter (PM2.5). Fine particulate matter — particles less than 2.5 micrometers across — comes mostly from combustion: vehicle exhaust, wildfire smoke, residential wood burning, and industrial emissions. Because these particles are small enough to enter the bloodstream, PM2.5 is the pollutant most strongly linked to cardiovascular disease, respiratory illness, and premature death.
Days by Dominant Pollutant (2023)
| Pollutant | Days as Dominant | Share of Year |
|---|---|---|
| Fine Particulate Matter (PM2.5) | 206 | 56% |
| Ground-Level Ozone | 109 | 30% |
| Coarse Particulate Matter (PM10) | 45 | 12% |
| Nitrogen Dioxide | 5 | 1% |
Is the Air Getting Better or Worse?
Air quality in El Paso, Texas has been getting worse over the past decade, with median AQI climbing by roughly 0.9 points per year. That bucks the national trend of broad improvement, and most often reflects either growing wildfire smoke exposure (particularly across the West) or rising local emissions from population and freight growth.
In 2014, El Paso, Texas posted a median AQI of 55. By 2023 that figure was 64 — a rise of 9 AQI points dirtier across 10 years of EPA records.
Year-by-Year AQI in El Paso, Texas

| 2015 | 54 | 128 | 7 | PM2.5 |
| 2016 | 55 | 123 | 6 | PM2.5 |
| 2017 | 56 | 120 | 23 | PM2.5 |
| 2018 | 59 | 91 | 17 | PM2.5 |
| 2019 | 57 | 100 | 13 | PM2.5 |
| 2020 | 59 | 95 | 19 | PM2.5 |
| 2021 | 59 | 91 | 19 | PM2.5 |

Health Context for El Paso, Texas
Across the past five years, this area has logged 90 days where AQI rose into the "Unhealthy for Sensitive Groups" range or worse — about 18 days per year. That is roughly typical for a U.S. metro, with most caution days clustered in summer (ozone) or wildfire season.
Treat daily AQI forecasts as essential input. On flagged days, sensitive groups (asthma, COPD, heart disease, pregnancy, young children, older adults) should limit outdoor exertion and keep windows closed. A HEPA air cleaner sized to a bedroom or family room can cut indoor PM2.5 by 80%+ during smoke or pollution events. Because PM2.5 penetrates deep into the lungs and bloodstream, an N95 or KN95 mask provides meaningful protection on smoky or high-particulate days — surgical masks do not.
How This Grade Is Calculated
The AirHistory Air Quality Grade combines four signals: the 5-year median AQI (40% of the score), the 10-year trend direction (30%), the count of unhealthy days per year (20%), and the dominant pollutant type (10%). All four come directly from the EPA Air Quality System (AQS), which aggregates readings from federally certified monitors. Read the full methodology.
