Albuquerque Air Quality: The Seasonal Shape
Which months are worst in Albuquerque, the mechanism behind them, and what five years of EPA monitoring actually shows.
Worst stretch in the EPA record: July, with August close behindAlbuquerque air quality at a glance
EPA record, 2020 to 2024Computed from EPA's daily AQI record for the Albuquerque, NM metro area, 2020 to 2024. The metro AQI for a day is the highest reading among its monitors, so this is the calendar as the whole metro experiences it.
Which months are worst for air quality in Albuquerque
Five years of EPA's official record for the Albuquerque, NM metro, 2020 to 2024, folded into one year: each bar splits the month's days into EPA's six categories, in EPA's exact colors, and beneath it sits the pollutant that most often set the index. Read the pollutant row and you can watch the mechanism change season: ozone is summer chemistry, winter PM2.5 is trapped air, late summer PM2.5 is usually smoke.
The three worst months, ranked
July
17.4% of monitored days reached Unhealthy for Sensitive Groups or worse, and 94% at least Moderate. The index was most often set by ozone. Worst single day: AQI 133 on July 24, 2024.
August
11.6% of monitored days reached Unhealthy for Sensitive Groups or worse, and 86% at least Moderate. The index was most often set by ozone. Worst single day: AQI 171 on August 8, 2021.
May
9.0% of monitored days reached Unhealthy for Sensitive Groups or worse, and 94% at least Moderate. The index was most often set by ozone. Worst single day: AQI 297 on May 21, 2022.
Why Albuquerque air goes bad when it does
Albuquerque sits at a mile high in a windy river valley: spring winds bring dust, summer sun brings ozone that has crept toward the federal standard, and fire smoke from anywhere in the Southwest can ride the Rio Grande corridor through town.

The AQI scale, in EPA's words
| AQI | Category | What it means |
|---|---|---|
| 0 to 50 | Good | Air quality is satisfactory, and air pollution poses little or no risk. |
| 51 to 100 | Moderate | Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. |
| 101 to 150 | Unhealthy for Sensitive Groups | Members of sensitive groups may experience health effects. The general public is less likely to be affected. |
| 151 to 200 | Unhealthy | Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects. |
| 201 to 300 | Very Unhealthy | Health alert: The risk of health effects is increased for everyone. |
| 301 and higher | Hazardous | Health warning of emergency conditions: everyone is more likely to be affected. |

Who EPA means by sensitive groups
| When this pollutant has an AQI above 100 | EPA lists these sensitive groups |
|---|---|
| Ozone | People with lung disease, such as asthma; children, including teenagers; people who are active outdoors; and older adults. |
| Fine particle pollution (PM2.5) and particle pollution (PM10) | People with heart or lung disease; older adults; and children, including teenagers. In addition, some minority groups, people with lower incomes, and outdoor workers may experience higher exposure that can worsen underlying health conditions. |
| Carbon monoxide (CO) | People with heart disease. |
| Nitrogen dioxide (NO2) | People with lung disease, such as asthma; children, including teenagers; and older adults. |
| Sulfur dioxide (SO2) | People with asthma; children, including teenagers; and older adults. |
What EPA says sensitive groups should do on an orange day
Sensitive groups: Make outdoor activities shorter and less intense. Take more breaks. Watch for symptoms such as coughing or shortness of breath. Plan outdoor activities in the morning when ozone is lower. People with asthma: Follow your asthma action plan and keep quick-relief medicine handy.

Sensitive groups: Make outdoor activities shorter and less intense. It's OK to be active outdoors but take more breaks. Watch for symptoms such as coughing or shortness of breath. People with asthma: Follow your asthma action plan and keep quick relief medicine handy. People with heart disease: Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider.
