Air quality today
The air quality in Brownsville, Texas is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 25.0 µg/m³. This assessment is based on a single valid measurement reported through OpenAQ.
Data for other pollutants are not available at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality dataset for Brownsville, Texas includes measurements for two pollutants: fine particulate matter (PM2.5) and ozone (O3). The data come from three individual rows representing two monitoring stations, so each pollutant is not covered uniformly across the city.
For PM2.5 the most recent reading was recorded on 2026‑02‑09 23:00 UTC at the Brownsville East 6th site, which falls within the “updated within 7 days” freshness category. Across the two rows that report PM2.5, values range from a minimum of 20.0 µg/m³ to a maximum of 25.0 µg/m³, with a median of 22.5 µg/m³ and the inter‑percentile spread (10th–90th) tightening between 20.5 and 24.5 µg/m³. This suggests that recent PM2.5 observations are clustered in a relatively narrow band.
In contrast, ozone data come from a single row at the Brownsville C80 location, with its last update on 2018‑01‑05 17:00 UTC—classified as “old data.” The sole O3 measurement is 0.042 ppm, and because there are no recent or additional readings, the dataset provides only a snapshot rather than a current picture of ozone levels in the city.
Overall, the dataset offers fresh, multi‑row coverage for PM2.5 but very limited and outdated information for ozone. Because monitoring points differ between pollutants, conditions can vary across neighborhoods and times, and the available data may not fully represent the present air quality throughout Brownsville.

Data notes
The data shown reflects a single valid measurement and is updated within 3 days, with the most recent reading recorded on 2026‑02‑09 at 23:00 UTC. This snapshot provides a brief view of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single point-in-time report.
