Air quality today
The air quality in Clearwater, Florida is classified as Good today. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 3.8 µg/m³ based on two valid observations reported through OpenAQ.
Overall conditions meet the criteria for a Good rating, and the available data reflect the current state of particulate matter in the area. 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 record for Clearwater currently draws from a single monitoring location, the St. Petersburg College site, which supplies one row of data for each pollutant tracked. Both ozone (O3) and fine particulate matter (PM2.5) are represented, and each has been refreshed within the last seven days, with the most recent timestamp recorded at 2026‑02‑10 23:00 UTC.
For ozone, the dataset contains a single value of 0.049 ppm. Because only one measurement is available, the minimum, median, maximum and percentile figures are all identical, indicating no observed variation across the reporting period. The same pattern holds for PM2.5, which shows a constant reading of 3.8 µg/m³ at the same timestamp and location. Consequently, the spread between low‑end and high‑end values is zero for both pollutants, and the typical (median) concentration matches the only reported figure.
The coverage is limited to one station, so spatial representation across Clearwater is minimal; conditions elsewhere in the city may differ from those captured at the St. Petersburg College site. Nonetheless, the data are recent, with no rows classified as old or of unknown freshness. Because each pollutant has exactly two rows that fall into the “updated within 7 days” bucket, the overall dataset is uniformly current but sparse in terms of both geographic breadth and temporal depth. Users should keep in mind that these point‑in‑time readings provide a snapshot rather than a comprehensive view of air quality throughout Clearwater.

Data notes
The current dataset for Clearwater includes two valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 23:00 UTC. These values reflect conditions at specific monitoring points and times; air quality can differ across neighborhoods and throughout the day, so this snapshot may not represent every location or moment in the city.
