Air quality today

The air quality in Worthing today is classified as Good. The primary pollutant identified is PM2.5.

Measurements indicate a PM2.5 concentration of 7.13 µg/m³, derived from seven valid readings collected through the OpenAQ network. These seven measurements provide the basis for the current assessment and reflect the latest available data for the city. No other pollutants have been highlighted as dominant in this report. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Worthing air‑quality dataset contains eight recent rows drawn from two monitoring stations and provides readings for seven measured variables: nitrogen dioxide (NO₂), fine particulate matter (PM2.5), coarse particles (PM10), ultrafine particles (PM1), relative humidity, temperature and the particle count metric UM003. The most up‑to‑date observations were recorded on 2026‑02‑10 at 21:00 UTC for PM2.5, PM1, relative humidity, temperature and UM003, while NO₂ was last updated a hour earlier on the same day (2026‑02‑10 20:00 UTC). The only older entry is the PM10 value from 2025‑01‑13 23:00 UTC, indicating that most pollutants have fresh data within the past week but coverage for PM10 is limited to an out‑of‑date measurement.

Across the recent rows the pollutant values show a narrow spread. PM2.5 ranges from 7.1305 to 8.0 µg/m³ with a median of about 7.57 µg/m³, and the 10th–90th percentile band (7.22‑7.91 µg/m³) confirms little variation among the recent samples. PM1 is recorded at a single value of roughly 3.26 µg/m³, while NO₂ is constant at 31 µg/m³ for its latest reading. Relative humidity sits at 71.9 % and temperature at 13.2 °C, each reported as a single recent measurement, and the particle concentration UM003 is consistently 720.3 particles per cm³.

Because only two stations contribute data, spatial coverage is modest and some pollutants rely on a single location (e.g., all recent PM1, humidity, temperature and UM003 values come from Tarring). The dataset therefore captures a snapshot of current conditions at those sites but may not reflect variations across the wider Worthing area.

Data notes

The data shown for Worthing is based on seven valid measurements and was refreshed Updated within 3 days, with the latest values recorded at 2026‑02‑10T21:00:00+00:00. This snapshot reflects conditions at a single point in time; air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured by these figures.
