Air quality today

The air quality today in Bremerton, Washington is classified as Moderate. The primary pollutant identified is PM2.5. Data is shown via OpenAQ and is based on a single valid measurement. The PM2.5 reference value associated with this measurement is 12.0 micrograms per cubic meter. A reference value for PM10 is not available.

The Moderate category reflects the level indicated by the available data. The assessment relies on one valid observation, which limits the breadth of the snapshot. No additional pollutants were reported in the current dataset, and the dataset does not include hourly trends or historical comparisons. The reported PM2.5 value aligns with the reference threshold used for categorization. Further monitoring may provide a more comprehensive picture.

What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Bremerton, Washington, the only pollutant reported by the OpenAQ feed is fine particulate matter, PM2.5, measured in micrograms per cubic meter. The dataset contains a single monitoring location, identified as Bremerton‑Spruce Ave, so the station coverage for this city is limited to one row.

All three statistical summaries—minimum, median, and maximum—are identical at 12.0 µg/m³, and the 10th and 90th percentiles match that same value, indicating no observed variation in the recorded measurements. The most recent timestamp attached to this reading is 2026-01-24 14:00 UTC, but the data is flagged as old, meaning it does not reflect current conditions. Because only one sensor contributes data and the record is dated, the available information cannot capture spatial or temporal changes across Bremerton, and actual air quality may differ from this single, static value.
