Air quality today

The air quality in Fort‑de‑France today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 5.3 µg/m³. In addition, the PM10 level stands at 11.9 µg/m³, based on five valid observations collected via OpenAQ.

These values reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Fort‑de‑France includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀) and particulate matter 2.5 µm or less (PM₂.₅). Across the city there are nine data rows drawn from four monitoring stations, giving a modest spatial coverage that captures conditions at several key locations such as the Hôtel de ville and the Concorde site.

For PM₁₀ the recent readings range from 11.9 to 24.5 µg/m³ with a median of 13.2 µg/m³; the 10th‑percentile sits just above 12 µg/m³ while the 90th‑percentile approaches 22 µg/m³, indicating most values cluster near the lower end of the observed spread. PM₂.₅ shows an even tighter band, from 5.3 to 6.9 µg/m³ with a median of 6.1 µg/m³ and percentiles that differ by only about 1.3 µg/m³, suggesting relatively consistent fine‑particle levels across the sampled sites.

Nitrogen dioxide values are also recent, ranging between 17.3 and 27.9 µg/m³ with a median of 22.6 µg/m³; the distribution is broader than that of PM₂.₅ but still centred around the mid‑twenties. In contrast, NO data are older – the latest entry dates from 2024‑03‑11 – and span 0.1 to 8.3 µg/m³ with a median of 4.2 µg/m³. This older timestamp means the NO record is less reflective of current conditions, highlighting an uneven freshness across pollutants.

Overall, three of the four pollutants have updates within the last few days (all recorded on 2026‑02‑10), while NO remains dated by nearly two years. The modest number of stations and rows provides a snapshot rather than exhaustive coverage, so actual air quality can vary in parts of Fort‑de‑France that are not directly represented by these measurements.

Data notes

The dataset for Fort‑de‑France includes five valid measurements and is refreshed regularly, having been updated within the past three days (last update 2026‑02‑10T15:00:00+00:00). These values represent a snapshot of ambient conditions at specific monitoring points; air quality can differ across neighborhoods and change throughout the day, so this information reflects only the recorded moments and locations.
