Air quality today

The air quality in Kobe is currently rated as Moderate. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 27.0 µg/m³ based on 65 valid observations collected via OpenAQ.

Data indicate that the prevailing conditions fall within the Moderate category, reflecting the reported PM2.5 level and measurement count. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Kobe’s open‑air quality feed includes six measured gases and particles – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). The dataset contains 65 recent observations drawn from 16 monitoring sites across the city, but the coverage is uneven: CO is reported from a single location in Kita‑ku, SO₂ from four points in Hyōgo‑ku, while NO, NO₂ and NOX each have fifteen stations and PM2.5 sixteen.

All pollutants show their latest reading timestamped 2026‑02‑10 22:00 UTC, so the most recent data are less than three days old. However, the number of records varies widely. For CO the single entry records a stable value of 0.3 ppm; SO₂’s four entries sit at a median of 0.0005 ppm with a maximum of 0.001 ppm; NO is measured at a median of 0.001 ppm and reaches up to 0.013 ppm; NO₂ and NOX share similar distributions, each with a median around 0.021–0.022 ppm, minima near 0.01 ppm and maxima of 0.026 ppm (NO₂) and 0.033 ppm (NOX). PM2.5 shows the broadest spread, ranging from 10.0 to 27.0 µg/m³ with a median of 16.5 µg/m³; the 10th‑percentile is 11.0 µg/m³ and the 90th‑percentile 23.0 µg/m³.

Because some pollutants are captured at only a handful of sites, city‑wide conditions can differ noticeably between neighborhoods and over short periods. The dataset’s overall freshness is good, but the limited station count for CO and SO₂ means those values reflect very localized conditions rather than a comprehensive city picture.

Data notes

The dataset for Kobe includes 65 valid measurements and is updated within 3 days, with the most recent values recorded at 2026‑02‑10T22:00:00+00:00. These figures represent a snapshot of conditions across the monitoring network; air quality can differ by location and time within the city, so individual experiences may vary from the reported averages.
