Air quality today

The air quality in Dallas today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 20.35 µg/m³ based on six valid observations reported through OpenAQ.

This assessment reflects the current conditions without additional commentary. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Dallas pulls information from nine measurement rows collected at three monitoring stations, covering the full set of pollutants tracked by OpenAQ in this city: ozone (O₃), fine particulate matter (PM₂.5), coarse particles (PM₁₀), ultrafine particles (PM₁), relative humidity, temperature, and particle count (UM003). The most recent observations are from 2026‑02‑11 00:00 UTC for PM₂.5, PM₁, relative humidity, temperature and UM003 at the Town Creek site, while ozone data is dated 2025‑02‑20 19:00 UTC from Dallas Hinton St. C4 and PM₁₀ dates back to 2025‑01‑13 23:00 UTC at Town Creek. This means that five of the seven pollutants have fresh readings within the past week, whereas ozone and PM₁₀ are based on older records.

Across the recent measurements, PM₂.5 values range from a low of 6.3 µg/m³ to a high of about 20.35 µg/m³, with a median of 9.6 µg/m³, indicating modest variability in fine particulate concentrations at the sampled location. The single‑point readings for PM₁ (11.69 µg/m³), PM₁₀ (0.79 µg/m³), relative humidity (43.86 %), temperature (23.49 °C) and UM003 (2121.14 particles/cm³) reflect the conditions recorded at Town Creek on the same day, so no spread can be reported for those parameters.

Overall, the data set provides a snapshot of several key air‑quality variables but is uneven in temporal coverage: half of the pollutants are represented by up‑to‑date values, while ozone and PM₁₀ rely on older entries. Because monitoring points are limited to three sites, conditions can differ across Dallas depending on location and time, so the figures shown represent only the specific moments and places captured by these sensors.

Data notes

The data shown reflects six valid measurements and was updated today (2026‑02‑11T00:00:00+00:00). These readings provide a current snapshot of ambient conditions across Dallas, Texas, but air quality can differ by neighborhood, time of day, and local sources. Consequently, the values represent an overall citywide average at the moment of collection and may not capture short‑term or location‑specific variations.
