Air quality today

The air quality in Reykjavik is currently classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 0.0 µg/m³. PM2.5 is the pollutant that determines the overall category in this assessment. The dataset includes 16 valid measurements collected over the reporting period, and the values are presented without adjustment. Data are displayed through OpenAQ.

For particulate matter, the reference value for PM10 is 14.025 µg/m³, providing a benchmark for the current reading. The PM10 reference value of 14.025 µg/m³ serves as a comparative point for particulate concentrations. These figures reflect the latest available observations for the city and are sourced from the OpenAQ platform. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Reykjavik air‑quality feed contains 29 recent rows collected from five monitoring sites. It records concentrations for carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter in three size fractions (PM₁, PM₂.₅ and PM₁₀) and sulfur dioxide (SO₂). The broader sensor suite also includes relative humidity, temperature and the UM003 parameter, but no rows for those three variables appear in the current extract. Freshness varies markedly: seven rows have been updated within the last 30 days, while the remaining 22 rows date back to 24 January 2026. The most recent timestamps are 10 February 2026 23:00 UTC for PM₂.₅, PM₁ and NO, and 10 February 2026 16:00 UTC for NO; all other pollutants show their latest reading on 24 January 2026 14:00 UTC.

Across the available data the measured values show a modest spread. PM₁₀ ranges from 0 µg/m³ to a peak of 14.025 µg/m³ at the Reykjavik Grensas site, with a median of 5.125 µg/m³, while PM₂.₅ stays between 0 µg/m³ and 3.3 µg/m³, median 1.467 µg/m³, and PM₁ varies from 0 µg/m³ to 0.8 µg/m³, median 0.3 µg/m³. NO exhibits a negative median (‑1.217 µg/m³) and spans from ‑3.415 µg/m³ to 0.980 µg/m³, indicating occasional readings below zero at Reykjavik Grensas. NO₂ values sit between 0.486 µg/m³ and 5.792 µg/m³, median 3.396 µg/m³. SO₂ reaches a maximum of 6.834 µg/m³, with a median of 3.567 µg/m³. CO and O₃ each have a single recorded value—89.77 µg/m³ for CO at Reykjavik Grensas and 23.912 µg/m³ for O₃ at Husdyragardurinn—both dated 24 January 2026. The uneven distribution of recent measurements and the concentration ranges suggest that air‑quality conditions in Reykjavik can differ noticeably between locations and over time, and that many of the available data points are older than a month.

Data notes

The dataset for Reykjavik includes 16 valid measurements and is updated within 30 days. The most recent data were recorded on 2026-02-10 at 23:00 UTC. This snapshot reflects conditions at the time of sampling; air quality can differ across neighborhoods and throughout the day, so values may not represent the entire city at any given moment.
