Air quality today

The air quality in Murcia today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 5.38 and a PM10 reference value of 13.74, based on eleven valid observations collected via OpenAQ.

These figures indicate that the current concentrations are within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Murcia includes measurements of carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). Data come from 24 rows recorded at two monitoring stations, the most recent values being collected on 2026‑02‑09 at 15:00 UTC for all pollutants except NO, which is based on a single older entry from 2024‑02‑20. For each pollutant the latest reading is listed as follows: NO₂ 17.7 µg/m³ (RONDA SUR), O₃ 73.6 µg/m³ (RONDA SUR), PM₁₀ 12.93 µg/m³ (RONDA SUR), PM₂.₅ 4.15 µg/m³ (RONDA SUR), SO₂ 3.0 µg/m³ (RONDA SUR), CO 40.0 µg/m³ (RONDA SUR) and NO 15.1 µg/m³ (SAN BASILIO).

Across the recent measurements the observed ranges are fairly wide: CO varies from 10 to 300 µg/m³, O₃ from 51.4 to 73.6 µg/m³, PM₁₀ from 12.93 to 32.16 µg/m³ and PM₂.₅ from 4.15 to 13.87 µg/m³, while the median values sit near the lower end of those spans (e.g., median CO 40 µg/m³, median O₃ 70.75 µg/m³). The percentile data show that most recent readings cluster toward the middle of their distributions – the 10th percentiles are close to the minima and the 90th percentiles approach the maxima for each pollutant.

Because only two stations contribute data, spatial coverage is limited; conditions can differ across neighborhoods that are not directly represented. Moreover, all pollutants except NO have been refreshed within the past week, whereas the lone NO record is over two years old, indicating a gap in recent information for that gas. Users should keep in mind that the snapshot reflects the specific monitoring points and timestamps rather than a city‑wide continuous picture.

Data notes

The data shown for Murcia are based on 11 valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
