Air quality today

The air quality in Manaus today is classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 0.0 µg/m³ based on five valid observations from OpenAQ.

No other pollutants reached reporting thresholds, and the data set includes five valid measurements for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Manaus contains a single monitoring row that reports five measured variables: PM1 at 0.0 µg/m³, PM2.5 at 0.0 µg/m³, relative humidity at 42.85 %, temperature at 33.83 °C, and UM003 particle count at 67.08 particles/cm³. All five values were last updated on 2026-02-10 18:00 UTC, so the most recent data are just a few days old.

Because only one station contributed data, the coverage is limited to that specific location and does not capture spatial variation across the city. The pollutant readings show no spread: each of the particulate metrics (PM1 and PM2.5) has a minimum, median and maximum of 0.0 µg/m³, indicating either a lack of detectable particles at the sensor or missing values. In contrast, relative humidity, temperature and UM003 each have a single recorded value, so their reported range is effectively zero. This uniformity means that typical (median) conditions are identical to the observed extremes for these three variables.

Overall the dataset is fresh in terms of timestamp but sparse in breadth; with only one row, many aspects of Manaus’ air quality—such as differences between neighborhoods or changes over time—cannot be assessed from this source alone. Users should keep in mind that city conditions can vary widely by place and moment, and additional measurements would be needed for a fuller picture.
