Air quality today

The air quality in Kamakura today is classified as Good. The primary pollutant identified is PM2.5, with a measured concentration of 3.0 µg/m³ based on nine valid observations reported through OpenAQ.

Overall conditions meet the criteria for a Good rating, and no additional pollutants are highlighted at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Kamakura air‑quality feed includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), combined nitrogen oxides (NOX), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). Data come from two monitoring sites that together contributed nine recent rows of observations. All values were last updated on 2026-02-10 22:00 UTC, so the dataset reflects conditions measured within the past three days.

Across the two stations the recorded concentrations are low and show little variation. CO was observed at a single value of 0.4 ppm at the Okamoto‑1018 location. NO ranged from 0.0 to 0.002 ppm with a median of 0.001 ppm, while its higher‑oxidation partner NO₂ varied between 0.001 and 0.004 ppm, median 0.0025 ppm, both measured at Okamoto‑1018. The combined NOX reading is a single point of 0.001 ppm from the Gosho‑18‑10 site. SO₂ was consistently zero ppm at the same Gosho location. PM2.5 values were confined to a narrow band between 2.0 and 3.0 µg/m³, median 2.5 µg/m³, also recorded at Okamoto‑1018.

The dataset’s breadth is uneven: three pollutants (CO, NOX, SO₂) are represented by only one row each, whereas NO, NO₂ and PM2.5 have two rows each, giving a modest overall coverage of nine recent measurements. Because the observations come from just two points in the city, they capture only a snapshot of local conditions; air quality can differ across other neighborhoods or at times outside the latest update window.

Data notes

The data shown reflects nine valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a brief view of current conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
