Air quality today
The air quality in Roatán is classified as Good today. The primary pollutant measured is PM2.5 (fine particles), with a reported concentration of 1.05 µg/m³ based on five valid observations from OpenAQ data.
No other pollutants reached reporting thresholds, and the limited dataset reflects consistent conditions across the measurement period. 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 Roatán dataset currently draws from five individual measurement rows collected at a single monitoring site operated by Roatan RMP – Sustenta Honduras. All five pollutants are represented: PM1, PM2.5, relative humidity, temperature and the particle counter UM003. Each parameter was last recorded on 2026-02-10 22:00 UTC, which falls within the “updated within three days” freshness window, so the data reflect a very recent snapshot of conditions at that location.
Because there is only one reporting station, the values shown are identical across the five rows – the minimum, median and maximum for each pollutant are the same. PM1 registers at 0.1894166698058446 µg/m³, while PM2.5 measures 1.0517500040224856 µg/m³. Relative humidity is recorded at 39.707861232757566 %, temperature at 32.737472195095485 °C and the UM003 particle concentration stands at 230.01468050214976 particles/cm³. The lack of variation means there is no observable spread or range for any of these metrics in this dataset.
The coverage is therefore limited: a single monitoring point provides the only available data for Roatán, so conditions elsewhere on the island are not captured here. While the timestamps are fresh, the dataset does not offer multiple locations or repeated measurements over time that would allow assessment of spatial differences or temporal trends. Users should keep in mind that air‑quality and related environmental parameters can differ across neighborhoods and throughout the day, even though the current snapshot is up‑to‑date for the reporting site.

Data notes
The data shown for Roatán reflects five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 22:00 UTC; it is considered “Updated within 3 days.” 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.
