Air quality today

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

Measurements from ten valid samples show a PM2.5 concentration of approximately 17.44 µg/m³, with no PM10 value reported. 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 Tema includes five measured variables: PM1, PM2.5, relative humidity, temperature and particle number concentration (UM003). All four sensor rows come from a single monitoring site – “Tema Community 3 SSNIT Flat” – so the station count is one, providing four recent observations per pollutant. The most recent timestamp across all variables is 2026‑02‑10 22:00 UTC, which means the data are updated within the last three days.

PM1 values range from about 3.8 to 21.6 µg/m³ with a median of roughly 15.7 µg/m³; PM2.5 spans 8.3 to 34.1 µg/m³ and has a median near 25.1 µg/m³, indicating that typical concentrations sit in the middle of each variable’s observed spread. Relative humidity varies between 56.4 % and 68.6 %, with a median of 68.3 %; temperature is recorded from 24.4 °C up to 29.2 °C, medianing at about 25.2 °C. The particle number concentration (UM003) shows the widest absolute range, from roughly 460 to 1 212 particles/cm³, with a median close to 994 particles/cm³.

Because all rows are recent and come from one location, the data give a snapshot of current conditions at that specific site but do not capture spatial variation across Tema. The freshness of each pollutant’s latest reading is identical (2026‑02‑10 22:00 UTC), so there is no lag between variables. However, with only four rows and a single monitoring point, the dataset cannot represent city‑wide patterns or temporal changes beyond this narrow window.

Data notes

The data shown for Tema reflects ten valid measurements and is updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 22:00 UTC. While this snapshot provides a current view of air quality across the Greater Accra Region, conditions can differ by specific neighbourhoods and times of day, so local variations may exist beyond what is captured here.
