Santa Fe Air Quality in 2025
This page covers what shapes air quality in Santa Fe over the course of a year: the pollutants that dominate locally, how conditions typically shift between seasons, and the local emission sources behind them. Measured 2025 annual statistics are published by EPA's Air Quality System, not here, so the AQI figure below is the latest observation available when this page was published.

The most recent EPA AirNow observation for the Santa Fe reporting area puts Santa Fe's AQI at 43 (Good), with ground-level ozone (O3) as the dominant pollutant — typical for the Southwest region. Observed 4:00 AM MDT on August 9, 2026. Reported by New Mexico Air Quality Bureau.
This is a single observation captured when the page was published, not a 2025 average. For measured annual and monthly statistics, use the EPA's Air Quality System reports.
How Santa Fe Air Quality Shifts Through the Year
Mar–May: Usually Santa Fe's cleanest stretch. Mild temperatures and better atmospheric mixing keep both ozone and particulates down.
Jun–Aug: Heat and sunlight drive ozone formation to its yearly peak. Afternoons are typically the worst time to be outside.
Sep–Nov: Air quality generally improves as temperatures drop, though early fall can still carry wildfire smoke in the Southwest region.
Dec–Feb: Cold-air temperature inversions can trap PM2.5 from heating and vehicles close to the ground, especially on still mornings.
Seasonal patterns above describe how pollution typically behaves in this region. They are not measured 2025 averages for Santa Fe.
Is It Safe to Exercise Outside in Santa Fe?
With Santa Fe's AQI at 43 (Good), outdoor exercise is generally safe for most people. Conditions are good for running, cycling, and outdoor sports at any time of day.

What's Causing Santa Fe's Air Pollution?
In Santa Fe, the leading pollutant is ground-level ozone (O3). As part of the Southwest region, the main drivers of air pollution here are:
- •Windblown dust and periodic dust storms (haboobs)
- •Vehicle emissions intensified by extreme summer heat
- •Rapid construction from population growth
- •Ground-level ozone formed in strong desert sunlight

Reduce Indoor Ozone in Santa Fe
Today's main pollutant in Santa Fe is ground-level ozone (AQI 43). Important: standard HEPA filters do NOT remove ozone — only a purifier with a substantial activated-carbon bed adsorbs it. The biggest wins are cutting indoor sources (gas appliances, certain "ionizer" purifiers) and ventilating when outdoor ozone is low (early morning). A high-carbon unit helps with the gases and VOCs that linger indoors.
