Air quality today
The air quality in Hakui is currently classified as Good. The main pollutant identified is PM2.5, with a measured concentration of 8.0 µg/m³ based on four valid observations reported through OpenAQ.
Overall conditions meet the criteria for a Good rating, and the available data reflect the latest recorded values for fine particulate matter. 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 data set for Hakui contains a single monitoring location, identified as 羽咋市旭町ユ２０, which supplies the full suite of measured pollutants — nitric oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX) and fine particulate matter (PM2.5). All four variables are present in the record, so the city’s air‑quality profile includes both gaseous nitrogen compounds and solid particles.
The most recent reading for each pollutant was recorded on 2026-02-10 at 22:00 UTC, meaning the data are less than three days old and fall into the “updated within 3 days” freshness category. Because there is only one row in the dataset, the station coverage is limited to a single point rather than a network that could capture spatial variation across Hakui. Nevertheless, the values themselves show very little variability: NO was measured at 0.0 ppm, while both NO₂ and NOX were each recorded at 0.001 ppm, with identical minimum, median, maximum, 10th‑percentile and 90th‑percentile figures for those gases. PM2.5 registered a consistent concentration of 8.0 µg/m³ across all statistical summaries.
These numbers indicate that the observed concentrations are essentially uniform at this site, with no spread between low and high readings for any pollutant. The dataset’s narrow temporal window (all values from the same timestamp) and single‑station design mean it cannot reveal day‑to‑day changes or differences between neighborhoods. Consequently, while the available data give a snapshot of current conditions at 羽咋市旭町ユ２０, they do not capture broader city‑wide fluctuations that may occur over time or across other locations.

Data notes
The data shown for Hakui reflects four valid measurements and is marked as Updated within 3 days, with the most recent update recorded at 2026‑02‑10T22:00:00+00:00. These values provide a snapshot of current conditions but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
