Air quality today

The air quality in Muskiz today is classified as Good. The primary pollutant identified is PM2.5. No other pollutant was identified as the primary pollutant. The assessment is based on nine valid measurements. The nine measurements represent the latest available data for the assessment period. Data are shown via OpenAQ.

Measured concentrations show PM2.5 at 1.0 µg/m³ and PM10 at 11.0 µg/m³, as reported by OpenAQ. The reference values applied are 1.0 µg/m³ for PM2.5 and 11.0 µg/m³ for PM10, matching the measured concentrations. These values are consistent with the Good air‑quality classification. The data reflect conditions at the time of measurement. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Muskiz pulls together 14 individual rows of air‑quality measurements collected at three monitoring stations across the municipality in the Autonomous Community of the Basque Country, Spain. Nine of those rows have been refreshed within the last 30 days, while the remaining five are older records. For most pollutants the most recent timestamp is 2026‑02‑09 15:00 UTC, indicating a fairly current snapshot, but the nitrogen monoxide (NO) reading dates back to 2024‑01‑16 22:00 UTC, so that particular value is considerably older than the rest.

The available pollutants are nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm (PM10), sulphur dioxide (SO2), nitrogen monoxide (NO) and fine particulate matter 2.5 µm (PM2.5). NO2 shows a measured range from 2.0 µg/m³ up to 8.0 µg/m³, with a median of 4.0 µg/m³, while ozone varies between 60.0 and 69.0 µg/m³, median 65.0 µg/m³. PM10 values are clustered tightly at the low end, with a minimum of 2.0 µg/m³ and a maximum of 11.0 µg/m³, the median also being 11.0 µg/m³, indicating that the higher end dominates the recent observations. Sulphur dioxide is reported at a single level of 5.0 µg/m³ (minimum 4.0, median 5.0), and PM2.5 is consistently 1.0 µg/m³ across its lone entry. The NO measurement is a flat 0.0 µg/m³ from the older record.

Coverage across pollutants is uneven: NO2, O3, PM10 and SO2 each appear in three rows, whereas NO and PM2.5 are represented by only one row each. This uneven distribution means that while the recent data give a clear picture for most gases and larger particles, the picture for NO and the finest particles relies on a single, less recent observation, and conditions can differ across locations and times within the city.
