Air quality today
The air quality in Boulder City today is classified as Moderate. The primary pollutant identified is PM10, with measured concentrations showing a PM2.5 value of 6.8 µg/m³ and a PM10 value of 66.0 µg/m³ based on three 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
Boulder City’s OpenAQ feed includes three measured pollutants – ozone (O₃), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µm (PM2.5). All of the data come from a single monitoring location, Garrett Jr. High, which contributes one row for each pollutant, giving a total of three rows in the dataset. The most recent update for every measurement was recorded on 2026-02-11 00:00 UTC, so the information is uniformly fresh across all three pollutants.
The ozone reading is reported as 0.044 ppm, and because there is only one observation the minimum, median, maximum and the 10th‑ and 90th‑percentile values are identical. Particulate matter shows a similar pattern: PM10 registers at 66.0 µg/m³ and PM2.5 at 6.8 µg/m³, with no variation among the statistical summaries. This lack of spread indicates that the dataset captures a single snapshot rather than a range of conditions over time or across multiple sites.
Because the coverage consists of just one sensor location, the data provide a precise picture of air quality at Garrett Jr. High on the date listed but do not reflect possible differences elsewhere in Boulder City or changes throughout the day. The uniform freshness and identical statistical values for each pollutant highlight that the current dataset is limited to a single point‑in‑time measurement rather than an ongoing series, so broader spatial or temporal patterns cannot be inferred from these numbers alone.
