Air quality today

The air quality in Austin, Texas is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 14.12 µg/m³ and a PM10 reference value of 26.0 µg/m³ based on fifty valid observations collected via OpenAQ.

These figures reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Austin’s OpenAQ feed currently includes seven measured pollutants: ozone (O₃), particulate matter 1 µm (PM1), PM₂.5, PM₁₀, relative humidity, temperature and particle count (UM003). The dataset comprises 55 individual rows collected from 12 monitoring stations across the city. Most of the recent measurements were recorded on 2026‑02‑11 at 01:00 UTC, giving a snapshot that is only a day old for PM1, PM₂.5, relative humidity, temperature, and UM003. The ozone reading comes from a single station updated on 2026‑02‑10 at 23:00 UTC, as does the PM₁₀ value, so those two pollutants have slightly older timestamps.

Across the available data the observed ranges are fairly wide. PM₂.5 values span from essentially zero up to about 14.9 µg/m³, with a median of roughly 8.1 µg/m³; the highest recent reading (14.12 µg/m³) was recorded in East Austin. PM₁ concentrations vary between 3.4 and 10.2 µg/m³, centering near 6.5 µg/m³, while PM₁₀ shows an extreme outlier of 26 µg/m³ at the Austin Webberville R site compared with a median of just 0.21 µg/m³. Relative humidity in East Austin ranged from about 38 % to 59 %, clustering around 55 %; temperature hovered between 20.5 °C and 24.3 °C, with a typical value near 22.1 °C. Particle counts (UM003) were observed from roughly 422 to 1850 particles per cm³, medianing at about 955, again with the highest recent reading (≈1795) in East Austin.

The coverage is uneven: while PM‑related metrics are reported from multiple stations (12 rows for PM₂.5 and 9 rows each for PM₁ and UM003), ozone and PM₁₀ rely on a single station each, limiting spatial detail for those pollutants. Overall the dataset is fresh for most variables but includes a few older points, so conditions can differ across neighborhoods and times of day.

Data notes

The data shown reflects 50 valid measurements and was Updated today (last refreshed on 2026‑02‑11T01:00:00+00:00). This snapshot provides a current view of Austin’s air quality, but conditions can differ across neighborhoods and change throughout the day, so values may vary depending on exact location and time of observation.
