Air quality today

The air quality in Dunedin today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 5.72 µg/m³ based on the latest data set. A total of 55 valid measurements were used to determine this assessment.

Data are shown via OpenAQ and reflect current monitoring conditions for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Dunedin air‑quality feed includes six measured variables – fine particulate matter (PM1), coarse particulate matter (PM10), fine particulate matter (PM2.5), relative humidity, temperature and particle count (UM003). The dataset contains 65 recent readings drawn from 12 monitoring sites across the city, giving a modest spatial picture of conditions at any one time.

For most pollutants the newest data were recorded on 2026‑02‑10 22:00 UTC, showing that the majority of the feed is up to date. PM1 values range from essentially zero to about 3.64 µg/m³ with a median of 1.32 µg/m³; PM2.5 spans 0 to 5.72 µg/m³ and sits at a median of 2.23 µg/m³, indicating typical concentrations are low but can rise several times higher than the central tendency. Relative humidity varies between roughly 50.7 % and 70.6 %, with a median near 65.6 %; temperature is recorded from about 14.4 °C to 18.7 °C, centering on 15.8 °C. The particle‑count sensor (UM003) reports values from 36 to 883 particles per cm³, median 391, showing a broad spread that may reflect local sources or meteorological influences.

PM10 is the outlier in terms of data freshness: its latest entry dates back to 2025‑01‑13 23:00 UTC, and only five rows are available for this metric. Consequently, coverage for PM10 is both older and sparser than for the other pollutants. Overall, while most variables have recent, moderately dense records, the uneven timestamp distribution—especially for PM10—means that city‑wide conditions can differ noticeably between locations and over time, and users should keep in mind that some aspects of the dataset are less current than others.
