Nye, Nevada 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, Nye, Nevada's most recent EPA year (2023) posted a median AQI of 19 (Good) against a 5-year median of 20 and an overall Grade of B. The dominant pollutant is Coarse Particulate Matter (PM10), which tells you which days are most likely to spike.
Check Today's Live AQI in Nye, Nevada
AirHistory is built on 10 years of EPA Air Quality System records, so it shows you what air quality in Nye, Nevada 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, Nye, Nevada posted a median AQI of 19 (Good), with 339 "Good" days and 6 days that crossed into "Unhealthy for Sensitive Groups" or worse. The dominant pollutant, Coarse Particulate Matter (PM10), is the one most likely to push today's number up — Coarse particulate matter — particles up to 10 micrometers across — typically comes from dust, construction sites, agriculture, unpaved roads, and natural sources like windblown soil. PM10 is less hazardous than PM2.5 because the larger particles do not penetrate as deeply into the lungs, but high levels still aggravate asthma and irritate airways.

Coarse particulate matter — particles up to 10 micrometers across — typically comes from dust, construction sites, agriculture, unpaved roads, and natural sources like windblown soil. PM10 is less hazardous than PM2.5 because the larger particles do not penetrate as deeply into the lungs, but high levels still aggravate asthma and irritate airways.
Days by Dominant Pollutant (2023)
| Pollutant | Days as Dominant | Share of Year |
|---|---|---|
| Coarse Particulate Matter (PM10) | 365 | 100% |
Is the Air Getting Better or Worse?
Air quality in Nye, Nevada has been getting worse over the past decade, with median AQI climbing by roughly 0.5 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, Nye, Nevada posted a median AQI of 20. By 2023 that figure was 19 — a drop of 1 AQI points cleaner across 10 years of EPA records.

Health Context for Nye, Nevada
Across the past five years, this area has logged just 22 days where AQI rose into the "Unhealthy for Sensitive Groups" range or worse — about 4 days per year, or roughly one every other month. That is a low count by national standards.
For most healthy adults, current air quality in this area does not require any change in behavior. People with severe asthma, COPD, or recent cardiac events should still keep an eye on daily AQI alerts, especially during wildfire season. PM10 is largely a near-source pollutant — staying upwind of busy roads, construction, and unpaved areas can substantially reduce exposure.
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.
