Air quality today
The air quality in Cudahy, California is rated as Good today. The primary pollutant identified is PM2.5 (fine particles).
A single valid measurement shows a PM2.5 concentration of 6.71 µg/m³. No PM10 value is available for this assessment. Data is shown via OpenAQ. 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
Cudahy’s OpenAQ feed includes six measured pollutants – nitrogen dioxide (NO₂), particulate matter of three size fractions (PM₁, PM₁₀ and PM₂.5), relative humidity and temperature – all recorded at the Elizabeth Learning Center (3548). The dataset contains nine rows drawn from two monitoring stations, but every row comes from the same site, so spatial coverage within the city is limited to that single location.
The timestamps show a mixed picture of freshness. The most recent measurement is PM₂.5, logged on 2026‑02‑10 23:04 UTC, while the other five parameters were last updated on 2024‑04‑24 02:06 UTC. NO₂ is considerably older, with its latest value from 2023‑05‑25 14:52 UTC. Because most of the data are over a year old, they capture only a snapshot of past conditions rather than current air quality.
Across the available records, PM₁ ranges from 2.0 to 14.9 µg/m³ with a median of 8.45 µg/m³, indicating modest variability. PM₁₀ shows a broader spread, from 7.73 up to 38.94 µg/m³ and a median of 23.34 µg/m³, while PM₂.5 varies between 6.71 and 16.5 µg/m³ with a median of 11.61 µg/m³. Relative humidity is constant at 55.52 % and temperature at –6.76 °C for the recorded moment, reflecting that only one reading exists for each of those variables.
Overall, the dataset provides a limited but concrete view of Cudahy’s air quality, with recent PM₂.5 data contrasting against older records for the other pollutants. Users should keep in mind that conditions can differ across neighborhoods and over time, especially given the age and single‑site nature of most observations.

Data notes
The data shown for Cudahy reflects a single valid measurement and was updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 23:04 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this single data point.
