Air quality today

The air quality in Brawley today is classified as Moderate. The primary pollutant identified is PM10, with a measured concentration of 57.0 µg/m³. In addition, the fine particulate matter (PM2.5) level is recorded at 0.18916666880249977 µg/m³ based on seven valid observations.

These values are presented through OpenAQ data for public reference. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Brawley pulls together data from two monitoring sites and a total of seven recent sensor rows. All six measured pollutants—PM1, PM2.5, PM10, relative humidity, temperature and UM003 (particle count)—are represented, but the depth of coverage varies markedly across them. The most up‑to‑date entries were recorded on 2026‑02‑11 at 01:00 UTC for PM2.5, PM1, relative humidity, temperature and UM003, while the PM10 reading dates back to 2026‑02‑10 at 23:00 UTC. Every pollutant’s latest timestamp falls within the past seven days, satisfying the “updated within 7 days” freshness criterion.

PM2.5 shows a modest spread, ranging from a low of 0.189 µg/m³ up to a high of 10.3 µg/m³, with a median value of about 5.24 µg/m³ and the 10th‑percentile at roughly 1.20 µg/m³ versus the 90th‑percentile near 9.29 µg/m³. In contrast, PM10 is reported as a single constant value of 57 µg/m³ from the Main Street location, offering no insight into variability. PM1 registers uniformly at zero across its sole observation, indicating either an absence of detectable particles in that size range or a limitation of the sensor data. Relative humidity and temperature are each captured once, both reporting identical values—28.79 % humidity and 27.25 °C respectively—so they provide only a snapshot rather than a range. The UM003 count is also singular, recorded at 176.84 particles per cubic centimetre.

Overall, the dataset gives a clear picture of PM2.5 variability but supplies only point measurements for the other pollutants. Because most metrics are based on one or two rows, they may not reflect day‑to‑day changes across Brawley. Users should keep in mind that conditions can differ by location and time, and the limited temporal depth means the current figures represent a narrow window rather than a comprehensive trend.

Data notes

The data shown for Brawley reflects seven valid measurements and was updated today (2026‑02‑11T01:00:00+00:00). These values represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
