Air quality today
The air quality in Porto Velho, Rondônia, Brazil is currently classified as Good. The primary pollutant measured is PM2.5. The latest reading shows a PM2.5 concentration of 0.92 µg/m³. Five valid measurements were used to determine this assessment. Data is shown via OpenAQ. The measurement period covered recent observations, and the values are expressed in micrograms per cubic meter. No PM10 data is currently available for this location.
With a Good rating and a PM2.5 level of 0.92 µg/m³, the air quality meets the criteria for this category. The Good classification indicates that the measured pollutant concentrations are within the range defined for this category. Air quality monitoring continues to provide updates through OpenAQ. 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 Porto Velho air‑quality record draws from a single monitoring site – the “Porto Velho – Brux” station – and contains five rows of observations. All five rows were captured within the last 30 days, with the most recent timestamp recorded on 2026‑01‑30 02:00 UTC. No older or unknown‑age entries are present, so the dataset reflects a very recent snapshot of conditions at that location.
For the pollutants that are tracked, the snapshot shows a PM1 concentration of 0.233 µg/m³, a PM2.5 concentration of 0.922 µg/m³, relative humidity of 55.79 %, temperature of 30.46 °C, and a particle count (UM003) of 208.18 particles/cm³. Each of these values appears as both the minimum, median and maximum across the five rows, indicating that the same measurement was recorded for every entry rather than a range of values over time.
Because the data come from only one station, the spatial coverage for Porto Velho is limited to that single point, and the lack of variation among the rows means the dataset cannot reveal how these parameters change across the city or over longer periods. Nevertheless, the information is fully up‑to‑date, with every recorded value dated within the last month, providing a clear, if narrow, picture of the city’s air‑quality profile at the time of measurement.
