What Does the D Grade Mean?

Eddy, New Mexico earns a D — air quality falls below the U.S. average, with a 5-year median AQI of 47. Residents with asthma, COPD, heart disease, or young children should watch daily AQI forecasts and limit outdoor exertion when alerts go out.

Eddy, New Mexico's 5-year median AQI of 47 is 6 points above the national average of 41 — meaningfully more polluted than the typical U.S. metro tracked here. Within New Mexico, Eddy, New Mexico runs more polluted than the state average of 34 — local sources or geography are concentrating pollution above the state's typical reading.

What's in Eddy, New Mexico's Air?

The dominant pollutant in Eddy, New Mexico is Ground-Level Ozone. Ground-level ozone forms when sunlight reacts with vehicle exhaust and industrial emissions. It is worst on hot, sunny, stagnant summer days. Ozone irritates the lungs, triggers asthma attacks, and reduces lung function — even healthy adults can feel chest tightness and shortness of breath after exercising in elevated ozone.

Is the Air Getting Better or Worse?

Air quality in Eddy, New Mexico has been getting worse over the past decade, with median AQI climbing by roughly 0.8 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, Eddy, New Mexico posted a median AQI of 41. By 2023 that figure was 49 — a rise of 8 AQI points dirtier across 10 years of EPA records.

Health Context for Eddy, New Mexico

Across the past five years, this area has logged 103 days where AQI rose into the "Unhealthy for Sensitive Groups" range or worse — about 21 days per year, or roughly one every five to seven days. That is well above the national norm and explains the D grade.

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 ozone peaks in the afternoon on hot sunny days, plan outdoor exercise for early morning or after sunset on bad-air days.

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.

Eddy, New Mexico has an Air Quality Grade of D (poor) with a 5-year median AQI of 47. The dominant pollutant is Ground-Level Ozone, and air quality has been worsening over the past decade.
