Air quality today
The air quality in North District, Hong Kong is currently rated as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 6.9 µg/m³ and a PM10 level of 15.6 µg/m³ based on five valid observations.
Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The North District air‑quality feed for Hong Kong includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). All data come from a single monitoring station, so the dataset contains one row per pollutant.
Each pollutant’s most recent reading was recorded on 2026‑02‑10 at 22:00 UTC, meaning the latest values are all less than three days old. The reported concentrations are identical for the minimum, median and maximum of each series, indicating that only a single measurement is currently available for every pollutant. CO registers at 485.2 µg/m³, NO₂ at 35.3 µg/m³, O₃ at 22.4 µg/m³, PM₁₀ at 15.6 µg/m³, PM₂.₅ at 6.9 µg/m³ and SO₂ at 3.9 µg/m³.
Because the dataset consists of just one observation per pollutant, there is no spread or percentile range to describe; the values are effectively point estimates rather than a distribution over time. The uniform freshness across all six pollutants shows that the station is reporting contemporaneously, but the lack of multiple rows means temporal variability cannot be assessed from this snapshot. Consequently, while the current numbers give an immediate picture of pollutant concentrations at the North District site, they do not capture how conditions may differ across other parts of the district or change throughout the day.

Data notes
The data for North District reflects five valid measurements and is marked as Updated within 3 days, with the latest reading recorded at 2026‑02‑10T22:00:00+00:00. This snapshot provides a brief overview of current conditions; however, air quality can vary by location and time within the city, so values may differ across neighborhoods or later in the day.
