Air quality today

The air quality in Bluffton, Indiana is classified as USG for today. The primary pollutant identified is fine particulate matter (PM2.5).

Measurements from five valid monitoring points show a PM2.5 concentration of 44.52 µg/m³. This figure reflects the current level recorded by OpenAQ data sources. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Bluffton air‑quality record draws from a single monitoring station that contributed six rows of data covering the full set of measured pollutants: PM1, PM10, PM2.5, relative humidity, temperature and UM003 particles. For five of those pollutants the most recent observation was logged on 2026‑02‑11 at 00:00 UTC, which falls within the “updated within seven days” window used by OpenAQ. The exception is PM10, whose latest entry dates back to 2025‑01‑13 23:00 UTC and is flagged as older data. Because only one station supplies the information, the dataset reflects conditions at that specific location rather than a citywide average.

All six pollutants show a single recorded value, so the minimum, median and maximum are identical for each. PM1 registers 28.29 µg/m³, while fine particulate matter (PM2.5) measures 44.52 µg/m³. Coarse particles (PM10) are reported at just 0.18 µg/m³, a figure that may be unusually low given the age of the measurement. Relative humidity stands at 46.66 % and temperature at 9.01 °C, providing a snapshot of the ambient environment on the day of recording. The UM003 count, expressed in particles per cubic centimetre, is 4 698.77, indicating the concentration of ultrafine particles detected by the sensor.

Because the dataset consists of a single recent timestamp for most variables and an older entry for PM10, there is limited temporal depth and no spread to illustrate variability over time. Users should keep in mind that air‑quality conditions can differ across neighborhoods and change throughout the day, so this point‑in‑time snapshot may not capture the full range of experiences within Bluffton.

Data notes

The data shown for Bluffton, Indiana reflects five valid measurements and was Updated today (last refreshed on 2026‑02‑11T00:00:00+00:00). These values represent a snapshot from the monitoring network at that time; air quality can differ across neighborhoods and change throughout the day, so conditions you experience may not exactly match this brief report.
