Air quality today
The air quality today in Richmond, Virginia is classified as USG. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 37.56 µg/m³ and a PM10 value of 6.0 µg/m³ based on 37 valid observations.
Data are shown via OpenAQ and reflect the current monitoring results for this location. 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
Richmond’s OpenAQ feed currently includes six measured pollutants: fine particulate matter (PM2.5), coarse particles (PM1), larger dust (PM10), relative humidity, temperature and particle count (UM003). The dataset draws from seven individual rows of sensor data collected at two monitoring sites in the city. For most pollutants the newest reading was taken on 2026‑02‑11 00:00 UTC, indicating that the information is fresh and reflects conditions within the last month. The exception is PM10, whose latest value dates back to 2025‑01‑13 23:00 UTC, so that particular metric is based on older data.
Across the recent observations, PM2.5 values range from a low of 19.0 µg/m³ to a high of 37.6 µg/m³, with a median of about 28.3 µg/m³ and most readings clustered between roughly 21 and 36 µg/m³ (the 10th‑90th percentile band). PM1 is represented by a single measurement of 25.0 µg/m³, while PM10 shows only one older value at 13.8 µg/m³. Relative humidity is recorded as a constant 42.9 % and temperature as a steady 12.2 °C for the latest timestamp. Particle concentration (UM003) is reported at 4,303 particles per cm³.
The coverage of pollutants is uneven: three of the six metrics (PM1, PM10, UM003) come from only one station each, whereas PM2.5 benefits from two recent readings. Because most rows are recent but a few remain dated, the snapshot captures current conditions for some parameters while others may not reflect today’s air quality across all neighborhoods. Users should keep in mind that local variations can exist beyond what these limited stations report.

Data notes
The dataset for Richmond, Virginia includes 37 valid measurements and is considered “Updated within 30 days,” with the most recent data recorded on 2026‑02‑11T00:00:00+00:00. This information reflects a single snapshot in time; air quality can differ across neighborhoods and fluctuate throughout the day, so conditions at any specific location or moment may not match the values shown here.
