Air quality today

The overall air quality today in Hobart, Tasmania is classified as Good. The main pollutant identified is PM2.5 (fine particles). Fifteen valid measurements were recorded for the assessment.

The average PM2.5 concentration is 3.42 µg/m³, as reported by OpenAQ. This figure reflects the current level of fine particulate matter in the city. No PM10 reference value is available for this period. The assessment is based on fifteen valid measurements collected across the city. The reported PM2.5 value is expressed in micrograms per cubic meter. All measurements are sourced from OpenAQ. The assessment does not include PM10 data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Hobart data set draws from 22 recent rows collected at five monitoring sites and includes six measured pollutants: PM2.5, PM10, PM1, RELATIVEHUMIDITY, TEMPERATURE and UM003. For PM2.5, PM1, RELATIVEHUMIDITY, TEMPERATURE and UM003 the newest observations were recorded on 2026-02-10 22:00 UTC, meaning these variables have been updated within the last three days. PM10 is the exception, with its latest reading dated 2025-11-27 12:50 UTC, so the PM10 record is older than three months. Overall, 15 rows are from the last three days, while seven rows are classified as old; no rows are marked unknown.

Across the recent data the measured values show modest variability. PM2.5 ranges from 0.0 to 3.42 µg/m³ with a median of about 1.23 µg/m³, while PM1 spans 1.56 to 1.95 µg/m³ and centers near 1.72 µg/m³. PM10 is tightly clustered between 1.0 and 1.18 µg/m³, median 1.0 µg/m³, reflecting the limited and older sample size (four rows from three stations). Relative humidity varies between 47.17 % and 49.06 % with a median of 47.88 %, and temperature fluctuates from 20.13 °C to 20.87 °C, median 20.44 °C. UM003 particle counts cover a broader spread, from 281 to 525 particles/cm³, with a median of roughly 454 particles/cm³.

The dataset therefore provides a recent snapshot for most pollutants but shows uneven coverage: PM10 has fewer and older entries, while the other five parameters benefit from more frequent, up‑to‑date sampling. Because the data represent specific stations at particular times, conditions in Hobart can differ across neighborhoods and moments not captured by the current rows.
