# Albuquerque, NM Air Quality Index (AQI) Today > Source: https://breathecheck.com/air-quality/us/new-mexico/albuquerque > Go, short outing, or stay in: a three-state verdict for Albuquerque plus its own 30-day AQI trend, and why winter and spring bad-air days are not the same problem. That reading and color are today's Albuquerque call, nothing more. It decides the bosque trail run, the kid's soccer practice, or whether the windows stay open tonight. This page tracks the air quality Albuquerque has actually breathed over the past 30 days, not just the number above. Set your own number instead — [a text lands when blowing dust pushes the reading past it](/alerts/). ## Albuquerque's last 30 days, not just today A single reading can't separate an ordinary day from a spring wind event. This chart rebuilds the air quality Albuquerque has seen over the trailing 30 days, from the same hourly AQI feed as the number above. It also carries a running count of **days above AQI 100 in the last 12 months**. IQAir, AccuWeather, aqicn and New Mexico's own monitor grid show today's number and stop there. A dusty spring afternoon that clears by the next morning still shows up here instead of disappearing. Albuquerque's own search demand shows that two-season shape rather than one annual flood. Averaged across the trailing year it runs 1,000 a month, against a typical month of 800. That's a 1.25x gap between the average and the typical month. Madison, on the same average-to-typical measure, runs 13.8x, because one Canadian smoke month carries its whole year. Here the demand spreads across a spring wind season and a summer monsoon instead. ## Why is it hazy in Albuquerque today? Three things can make Albuquerque's sky look worse than the number reads. The AQI is a 24-hour average, so one windy hour gets diluted across twenty-three calmer ones. Blowing dust is patchy — a gust front can wall off the West Side and leave the Northeast Heights clear. And the nearest station may sit far from wherever you actually are. A calm reading downtown says less about Rio Rancho or the East Mountains than it looks like it does. None of that makes the haze fake — one number averages one location, not your block. [Blowing dust, smoke aloft, or a 24-hour average](/why-is-the-air-bad-today/) covers every way a sky and a number stop agreeing. ![Bar chart of monthly US search volume for “air quality albuquerque” in Albuquerque, twelve months from Aug 2025 to Jul 2026.

Search volumes, not AQI readings — bars are neutral blue-grey with the peak month in accent blue, never EPA band colours, so demand data can never be read as a measurement of the air.* ## What is causing the bad air in Albuquerque? Albuquerque's dust doesn't run on the same calendar as Phoenix's or Tucson's. New Mexico's worst wind events cluster in spring, March through May. Cold fronts push through ahead of the summer monsoon and can lift dust across the whole Rio Grande valley at once. The monsoon itself arrives later, June through September, layering a second, shorter dust season on top of the spring one. Either way the pollutant is the same: coarse, wind-lofted [PM10](/aqi/) particulate matter, not the fine PM2.5 that dominates wildfire smoke. Winter runs on a separate mechanism. Albuquerque sits low in the Rio Grande valley, boxed in by the Sandia Mountains to the east and the West Mesa's volcanoes to the west. That shape traps cold, dense air near the ground on calm nights — a thermal inversion, the same basic mechanism behind Denver's brown cloud. It holds vehicle exhaust and wood smoke down instead of letting them disperse. We haven't found Albuquerque-specific reporting on the winter pattern, so this is the general valley mechanism, not a sourced local account. A third source arrives from outside the state. Smoke that reaches Albuquerque often didn't start in New Mexico — it drifts in from fires in Arizona, Colorado or, in a bad year, California. [The full mechanics of wildfire smoke](/wildfire-smoke/) covers how that differs from ordinary blowing dust. ## Is the air safe to breathe in Albuquerque today? This is a three-way call, not a yes-or-no. **Go**: nothing changes. **Short and unloaded**: the shorter bosque loop, not a cancelled walk. **Don't go** means exactly that. How long and how hard are two different dials, not one. Albuquerque's dust doesn't cover the metro evenly. A gust front can wall off the West Side and leave the Northeast Heights clear the same afternoon. So the number you're reading may not match the block you're standing on. EPA's warning to everyone opens at 151, Unhealthy. 201 to 300, Very Unhealthy, is that same warning turned up, not a new group joining it. Past roughly 200, the bosque trail waits — dust wall or clear sky nearby. ## What AQI should you stay inside? No New Mexico agency has published an AQI cutoff for schools or daycares — not the state Environment Department, not Albuquerque Public Schools. Only two states anywhere in the material this project reviewed have a real number: Washington and Minnesota. [The two states that publish a number](/daycare-air-quality-policy/) covers both. Ask your own provider for their written version instead of assuming one exists. ![Two EPA AQI colour scales for reading Albuquerque's number. The upper strip runs the whole index 0 to 500 in six bands, each segment as wide as the range it covers: Good 0-50 green, Moderate 51-100 yellow, Unhealthy for Sensitive Groups 101-150 orange, Unhealthy 151-200 red, Very Unhealthy 201-300 purple, Hazardous 301-500 maroon. The lower strip expands the 0-150 decision zone and marks three thresholds real readers set for themselves: AQI 60 (asthmatic runner), AQI 100 (parent / MN school), AQI 110 (runner).](/img/albuquerque/inline-1.webp) *EPA AirNow's own colours and breakpoints. The three marked cutoffs are not EPA guidance and not Albuquerque rules — each is one reader's or one institution's own line.* Runners, parents and asthmatics don't share a cutoff, and none of theirs matches the EPA's single sensitive-groups line. On r/Marathon_Training, one runner drew it at 110: "I'll run in up to 110 because...error bars." Parents this project has seen online land closer to 100, the point a group outing gets cancelled instead of shortened. An asthmatic runner went further, logging 156 runs against AQI to find a personal wall at 60. Past it, "my lungs struggle regardless of how well I've trained," though EPA calls nothing under 100 unhealthy. The pattern in their log: 87% of runs under 50 went fine, 42% between 50 and 70, just 12% past 70. Smoke reaching Albuquerque almost always started somewhere else, and it drags every one of those numbers down about one EPA band once it arrives. The EPA's own scale puts [101–150 in Unhealthy for Sensitive Groups](/aqi/) — its wording, not a verdict on any one reader's lungs. Indoors, the default is a portable HEPA purifier or a Corsi-Rosenthal box. One builder priced theirs at $130 for a 12x14 bedroom, built rather than shipped. A whole-house MERV-13 swap needs a static-pressure check from a licensed tech first. It can choke airflow in a system that isn't sized for it. [Which to buy first, monitor or purifier](/indoor/) settles the order. ## Why our number may not match what you are seeing and smelling Ground-level ozone is invisible and odorless wherever it forms, Albuquerque included. On a clear, still summer afternoon the reading can run higher than the sky suggests. That's the same gap that shows up in Phoenix, Denver and Los Angeles. There's no smelling your way to a safe read on it. The reverse happens too, on a shorter clock than most expect. A morning hazy from an overnight valley inversion can read moderate by noon. This happens once the average smooths the spike and the sun burns the inversion off. Checking once, at the wrong hour, gives a different picture than the day actually had. That's the monitoring station behind today's reading — its distance from downtown, and the nearby PurpleAir sensor count. A station miles off under-reports whichever side of the valley sits farthest from it. That's worst during a spring wind event the station on the other side of the Rio Grande never saw. [Why one station can miss a whole side of the valley](/methodology/) is documented in full. [Tucson, where the monsoon does the lifting](/air-quality/us/arizona/tucson) and [Phoenix, where the same dust arrives as a haboob](/air-quality/us/arizona/phoenix) sit further south on this corridor. ## FAQ ### What's the air quality forecast for Albuquerque tomorrow? Wind and inversion conditions can each shift within a day, especially heading into a spring wind event. Treat it as a direction, not a lock, and recheck the morning of. ### What's the UV index in Albuquerque today? UV runs on its own scale, separate from AQI. Albuquerque's high elevation and clear desert skies push UV higher than sea-level cities at the same latitude. That's why a good AQI reading is no reason to skip sunscreen. ### Who has the worst air quality in the US right now? The air quality Albuquerque reports moves hardest during an active spring wind event or wildfire smoke drifting in from another state. See [where the Rio Grande valley sits on today's national board](/) against every tracked city. ### Why does it smell like smoke outside in Albuquerque? Blowing dust doesn't usually carry a smell. If what you're noticing is actual smoke, it likely started outside New Mexico, in Arizona, Colorado or California, not from a local source. [Whether that smoke is at ground level or still overhead](/wildfire-smoke/) separates it from a dust event. ### Why is Albuquerque's air worse in a calm winter than a windy spring? They're different pollutants, not the same problem twice. Winter's temperature inversion traps fine PM2.5 near the ground on calm nights; spring's wind events kick up coarse PM10 dust instead, usually clearing within a day. The AQI treats both as a single number, even though they don't look, smell or behave alike.
