Air quality today

The air quality in Dakar today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements from five monitoring stations show a PM2.5 concentration of 24.5 µg/m³. Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Dakar pulls measurements from three monitoring sites and contains a total of seventeen recent records. All six pollutants tracked by OpenAQ are represented: fine particles (PM1, PM2.5, PM10), relative humidity, temperature, and particle number concentration (UM003). For five of the variables – PM1, PM2.5, relative humidity, temperature and UM003 – the most recent observations were all logged on 2026‑02‑04 at 10:00 UTC, meaning the newest data are less than a month old. The PM10 readings lack a timestamp, so their freshness cannot be assessed.

Across the available records the observed values span a fairly wide range. PM1 concentrations vary from just over three micrograms per cubic metre up to about twenty‑six µg/m³, with a median near nine µg/m³; PM2.5 shows a broader spread from roughly ten to thirty‑seven µg/m³ and a median of 24.5 µg/m³. Relative humidity ranges between 42 % and 81 %, centering around a typical value of 56 %; temperature fluctuates from about 22.9 °C to 31.3 °C, with most readings clustered near 24 °C. Particle number concentrations (UM003) are recorded between roughly 752 and 1 685 particles per cubic centimetre, the median being close to 786.

The coverage is uneven: while PM1, PM2.5, humidity, temperature and UM003 each have three stations contributing recent data, PM10 is only represented by two stations and lacks a current timestamp, limiting its usefulness for real‑time insight. Consequently, most of the city’s air quality picture relies on the five well‑documented pollutants, and conditions can differ across neighbourhoods and times of day that are not captured in this snapshot.
