This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Rochford today falls into the Moderate category according to the latest assessment. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 26.23 µg/m³ based on five valid readings collected via OpenAQ.
Overall, the data indicate that particulate matter levels are currently moderate, with no additional pollutants highlighted in this report. 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 dataset for Rochford currently draws from a single monitoring site and contains five recorded observations, one for each pollutant measured at the same moment on 2026‑02‑05 21:00 UTC. The available pollutants are PM1, PM2.5, relative humidity, temperature and particle count (UM003). For PM1 the value is 9.256 µg/m³, while PM2.5 registers 26.2338 µg/m³; both figures come from a Rayleigh‑distributed estimate and share identical minimum, median and maximum values because only one reading exists. Relative humidity is reported as 66.9725 % and temperature as 12.1158 °C, again with no spread beyond the single observation. The particle concentration measured by UM003 stands at 598.8357 particles per cm³, also derived from a Rayleigh distribution.
Because all five measurements were last updated on the same date and time, the data are uniformly fresh, but the coverage is limited to one location and a single snapshot in time. Consequently there is no range or variability to describe across multiple stations or dates; each pollutant’s minimum, median and maximum are identical. This lack of temporal depth means that while the current reading gives an up‑to‑date picture for that specific spot, conditions elsewhere in Rochford or at other times may differ.
In summary, the dataset includes five key atmospheric variables from one monitoring point, all recorded within the last 30 days, but it does not provide broader spatial or temporal insight beyond this isolated measurement.

Data notes
The data shown for Rochford is based on five valid measurements and was updated within 7 days, with the latest refresh recorded at 2026‑02‑05T21:00:00+00:00. While this snapshot provides a current view of air quality across the city, conditions can differ by specific neighbourhoods and change throughout the day, so individual experiences may vary from the reported values.
